How Do I Install Pokémon Yellow Advanced 2019?

Pokémon Yellow Advanced 2019 is a completed enhancement hack of the original Pokémon Yellow by ericgall23. Rather than replacing Kanto with an entirely new region, it takes Pokémon Yellow’s familiar adventure and modifies it with new gameplay ideas, quality-of-life improvements, altered battles, additional content, new player sprites, and other changes intended to make the original game feel less limited.

The project’s canonical community page is ericgall23’s Pokémon Yellow Advanced 2019 PokéCommunity thread, created in April 2019. Current ROM-hack catalogs still identify the project as completed and do not surface a newer creator-approved release replacing the 2019 build.

For a normal installation, the basic idea is:

Clean English Pokémon Yellow + official Pokémon Yellow Advanced 2019 patch = Pokémon Yellow Advanced 2019

The correct standard English Pokémon Yellow base has SHA-1:

cc7d03262ebfaf2f06772c1a480c7d9d5f4a38e1

That hash is documented by the pret Pokémon Yellow disassembly.

One important caveat before we start: I could not verify the original patch file extension from the currently indexed primary PokéCommunity thread. The thread itself is still the correct project source, but its attachment details are not exposed through current indexing. That means I am not going to confidently tell you “it is IPS” or “it is BPS” without proof.

Use the actual patch supplied by the creator/project thread and choose a patching tool that supports the file extension you receive.

Rom Professor does not host, provide, or link to copyrighted Pokémon Yellow ROM files or pre-patched Pokémon Yellow Advanced 2019 ROMs. Use your own legally obtained clean Pokémon Yellow ROM and apply the fan-made patch yourself.

What You Need Before Installing Pokémon Yellow Advanced 2019

You need:

A clean English Pokémon Yellow ROM
The Pokémon Yellow Advanced 2019 patch from the creator/community project source
A ROM patcher compatible with the supplied patch format
A Game Boy/Game Boy Color emulator
Normal battery-save support
A backup of your clean Pokémon Yellow ROM
A safe location for your Pokémon Yellow Advanced 2019 save

The Rom Professor question-bank brief specifically treats Yellow Advanced 2019 as a Yellow enhancement / catch-em-all-hack cluster and calls for a setup guide covering safe patching, base-ROM verification, emulator configuration, updates, troubleshooting, and FAQs.

What Is the Latest Version of Pokémon Yellow Advanced 2019?

Pokémon Yellow Advanced 2019 does not appear to use the clean modern version-number system you see in projects such as Radical Red or PureRGB.

The creator’s official PokéCommunity thread dates from April 2019. Current third-party catalogs continue to list the hack as:

Created by ericgall23
Based on Pokémon Yellow
Complete
Last updated in April 2019

and I could not verify a newer creator-approved edition replacing it.

So, as of August 30, 2026, the most accurate wording is:

Latest verified release: the completed Pokémon Yellow Advanced 2019 build

I would not invent a version number such as:

v1.0
v1.5
v2.0

unless an original project archive explicitly gives one.

For publication, use:

Pokémon Yellow Advanced 2019 — Completed 2019 Release

For future changes, see our Pokémon Yellow Advanced / Yellow hacks latest version guide.

Is Pokémon Yellow Advanced 2019 Complete?

Yes.

Current catalogs still identify Pokémon Yellow Advanced 2019 as a completed project rather than an unfinished demo.

Players were already reporting completing the game in 2019, shortly after the project’s release.

That makes this different from a ROM hack where you play through four Gyms and eventually hit unfinished content.

The intended Kanto progression remains playable through:

Eight Gym Leaders
Elite Four
Normal Pokémon Yellow-style main-game completion

Secondary documentation also lists additional systems including inverse battles and new optional areas referred to as Realms.

What Does Pokémon Yellow Advanced 2019 Change?

Yellow Advanced is not simply:

“Yellow, but every Pokémon is catchable.”

It is a broader enhancement project.

The surviving community documentation lists features including:

New male and female protagonist sprites
Inverse wild battles
Inverse Trainer battles
Realms
Eight Gym Leaders and the Elite Four
Updated Pokémon Centers
Altered dialogue
A Black/White-style Repel system

An independent ROM-hacking resource also describes Yellow Advanced 2019 as a hack intended to fix or improve many of the problems present in the original Pokémon Yellow.

That makes it a more heavily modified experience than something designed solely to make the original 151 obtainable.

Pokémon Yellow Advanced 2019 vs. Pokémon Yellow 151

These two games are easy to confuse because both are Pokémon Yellow enhancement hacks, but they have different goals.

Pokémon Yellow Advanced 2019

Yellow Advanced is a broader reworking of Pokémon Yellow.

It includes altered gameplay systems, new battle concepts, additional content, visual changes, and quality-of-life improvements.

Pokémon Yellow 151

Pokémon Yellow 151 by Razormime has a much narrower design philosophy.

Its creator describes it as a patch for emulator players who want to:

Play something very close to original Yellow
Complete the Pokédex legitimately
Obtain all 151 Pokémon
Access Surfing Pikachu/beach-house content
Avoid relying on external trading or cheat codes

Which Should You Install?

Choose Pokémon Yellow Advanced 2019 if you want:

More noticeable gameplay changes
New systems
Different battles
Additional content
A more heavily modified Yellow experience

Choose Pokémon Yellow 151 if you mainly want:

Vanilla Yellow
All 151 obtainable
Minimal disruption to the original experience

For this guide:

we are installing Pokémon Yellow Advanced 2019.

What Base ROM Does Pokémon Yellow Advanced 2019 Use?

Use:

Pokémon Yellow Version: Special Pikachu Edition — USA / Europe English

The official project is explicitly a Pokémon Yellow hack, while secondary documentation identifies the base as English Pokémon Yellow.

The standard English Pokémon Yellow SHA-1 is:

cc7d03262ebfaf2f06772c1a480c7d9d5f4a38e1

The pret Pokémon Yellow project identifies that exact ROM as:

Pokemon Yellow (UE) [C][!].gbc

Pokémon Yellow Base-ROM Verification

Item	Correct Value
Game	Pokémon Yellow Version: Special Pikachu Edition
Region	USA / Europe
Language	English
Common ROM designation	Pokémon Yellow (UE)
SHA-1	`cc7d03262ebfaf2f06772c1a480c7d9d5f4a38e1`
Size	1 MiB / 1,048,576 bytes
Base ROM should already be hacked?	No

The same retail Yellow release is cataloged independently with that SHA-1.

Do Not Use Pokémon Red or Blue

Yellow Advanced is specifically based on:

Pokémon Yellow.

Do not use:

Pokémon Red
Pokémon Blue
Japanese Pokémon Yellow
Pokémon Yellow 151
Yellow Legacy
Yellow Kaizo
Yellow Plus
Another modified Yellow ROM

Use a clean English retail Yellow ROM.

Do Not Patch Over Another Pokémon Yellow Hack

This is another common mistake.

Do not take:

Pokemon Yellow Legacy.gbc

and apply Yellow Advanced to it.

Do not use:

Pokemon Yellow 151.gbc

either.

The patch expects the original game’s data to be in specific locations.

Stacking unrelated hacks can produce:

Broken maps
Invalid text
Corrupted Trainers
Incorrect Pokémon data
White screens
Crashes later in the game

Always start from:

clean Pokémon Yellow.

Where to Get Pokémon Yellow Advanced 2019 Safely

The canonical project page is the creator’s PokéCommunity thread:

Pokémon Yellow Advanced 2019 official PokéCommunity thread

Search indexing identifies:

ericgall23

as the thread starter and confirms it is the Pokémon Yellow Advanced 2019 project thread.

That is the source I would trust first for:

Original project information
Creator attribution
Patch/package references
Release notes
Screenshots

Avoid treating random “download ROM” websites as the project’s official home.

Why You Should Avoid Pre-Patched ROM Downloads

A pre-patched file is a complete Pokémon Yellow ROM with the hack already applied.

Besides redistributing copyrighted base-game data, it makes verification harder.

A random file named:

Pokemon Yellow Advanced 2019.gbc

could actually contain:

The correct completed build
An old build
An unofficial edit
Cheats
Another Yellow hack
A corrupted ROM
A bad dump
A mislabeled Yellow 151 file

Patching the hack yourself lets you control:

The base ROM
The project patch
The resulting game file

That makes troubleshooting much easier.

What Patch Format Does Pokémon Yellow Advanced 2019 Use?

The honest answer from the currently accessible sources is:

I could not verify the original patch extension from the creator’s indexed PokéCommunity material.

That is important because older ROM-hack guides often guess:

IPS

simply because IPS was common for Game Boy hacks.

That may be correct, but it is not something I can responsibly present as confirmed without seeing the original project archive.

So:

Check the Actual File You Download

If the project archive contains:

.ips

use an IPS-compatible patcher.

If it contains:

.bps

use a BPS-compatible patcher.

If it contains:

.ups

use a UPS-compatible patcher.

A multi-format patching tool can make this easier.

Floating IPS, for example, supports IPS, BPS, and UPS patch formats.

Do not rename the patch extension to make it fit a particular tutorial.

How to Patch Pokémon Yellow Advanced 2019

Step 1: Get the Project Patch

Start with the creator’s PokéCommunity project thread.

Open the Pokémon Yellow Advanced 2019 project page

You are looking for:

the fan-made patch or project archive

not a complete pre-patched Pokémon Yellow ROM.

Step 2: Extract the Download

If the project package comes as:

.zip

.rar

or:

.7z

extract it first.

Inside, look for:

A patch file
README
Instructions
Documentation

Read the included instructions before patching.

Step 3: Identify the Patch Extension

Check whether the patch ends in:

.ips
.bps
.ups
Another documented patch format

Use a compatible patcher.

Do not assume the format based on an unrelated Yellow hack.

Step 4: Prepare Clean English Pokémon Yellow

Your base ROM should match:

SHA-1: cc7d03262ebfaf2f06772c1a480c7d9d5f4a38e1

If your ROM does not match:

stop and determine why.

Possible causes include:

Wrong region
Japanese Yellow
Modified ROM
Another hack
Bad dump

Step 5: Keep a Clean Backup

Create a permanent untouched copy.

For example:

Pokemon Yellow CLEAN.gbc

Never patch your only base ROM.

Keeping one clean copy means you can:

Repatch
Troubleshoot
Try another Yellow hack
Recover after choosing the wrong patch

Step 6: Open the Correct Patcher

If the patch is IPS:

use an IPS-capable tool.

If it is BPS:

use a BPS-capable tool.

If it is UPS:

use a UPS-capable tool.

A multi-format patcher is convenient because it reduces the chance of picking the wrong program.

Step 7: Select Pokémon Yellow as the Source

Choose:

Pokemon Yellow CLEAN.gbc

or your equivalently named clean Yellow ROM.

Do not select:

The patch
Another Yellow hack
Your .sav
A ZIP archive

Step 8: Select the Yellow Advanced Patch

Choose the project patch file.

Your patcher should now have:

Source ROM: Pokémon Yellow

Patch: Pokémon Yellow Advanced 2019

Step 9: Apply the Patch

Run the patching process.

Save the resulting game separately.

For example:

Pokemon Yellow Advanced 2019.gbc

Do not overwrite the clean base.

Step 10: Open the Finished ROM in an Emulator

Launch a Game Boy/Game Boy Color emulator.

Open:

Pokemon Yellow Advanced 2019.gbc

Do not open the patch file itself.

Step 11: Verify That You Are Not Playing Vanilla Yellow

Look for Yellow Advanced-specific changes such as:

Different protagonist graphics
Modified Pokémon Centers
New dialogue
Revised battle behavior
Repel-system changes
Other altered content

The hack’s documented feature list includes those types of changes.

Step 12: Make a Normal Test Save

Before committing to the playthrough:

Start the game.
Make a normal in-game save.
Close the emulator completely.
Reopen Yellow Advanced.
Confirm Continue appears.
Load the game.
Save again.

That ensures your emulator is writing the battery save correctly.

Suggested screenshot: Capture your own patching screen showing clean Pokémon Yellow as the source and the Yellow Advanced patch as the patch file. A second excellent image would be the official PokéCommunity project page.

Best Emulator for Pokémon Yellow Advanced 2019 on Windows

For Windows, I recommend:

SameBoy

SameBoy supports:

Game Boy
Game Boy Color
Super Game Boy
Battery saves
Save states
Accurate hardware emulation

That makes it especially useful for Pokémon Yellow, which can be displayed differently depending on whether you emulate:

Original Game Boy
Super Game Boy
Game Boy Color

BGB

BGB is another excellent Generation 1 emulator, particularly for players who like a traditional Windows GB/GBC emulator.

mGBA

mGBA also supports:

Game Boy
Game Boy Color
Battery saves
Game Boy palette behavior

and remains a convenient option if you already use it for GBA ROM hacks.

My Windows Pick

Use:

SameBoy

If something behaves strangely:

test the same ROM in BGB or mGBA before repatching.

Best Emulator for Pokémon Yellow Advanced 2019 on Mac

Use:

SameBoy

or:

mGBA

SameBoy supports macOS natively and provides accurate Game Boy/Game Boy Color emulation plus battery saves.

No special Yellow Advanced configuration should be necessary.

Start with normal defaults.

Can I Play Pokémon Yellow Advanced 2019 on Android?

Yes.

Because Yellow Advanced is still a Game Boy/Game Boy Color Pokémon Yellow hack, it can run in a normal accurate GB/GBC emulator.

A good option is:

RetroArch + SameBoy core

The SameBoy core supports:

.gb
.gbc
Battery saves
Save states
Game Boy
Game Boy Color

Other accurate Game Boy emulators can also work.

Android Setup

Patch Yellow Advanced first.
Transfer the completed ROM to your Android device.
Import/open it in your emulator.
Start a new game.
Make an in-game save.
Close the emulator completely.
Reopen it.
Confirm Continue works.

Do not try to open the patch file directly as a ROM.

Can I Play Pokémon Yellow Advanced 2019 on iPhone or iPad?

Yes.

SameBoy has a current iOS version and supports importing Game Boy and Game Boy Color ROM files.

Delta also lists:

Game Boy (Color)

among its supported systems.

For iOS:

Patch Yellow Advanced before importing it.
Import the finished .gb or .gbc ROM.
Start the game.
Make an in-game battery save.
Restart the emulator.
Confirm the save loads.

Should You Run Yellow Advanced in Game Boy Color Mode?

Pokémon Yellow itself has built-in Game Boy Color enhancements.

For most modern players:

Game Boy Color mode is the easiest recommendation.

The pret project identifies the standard English Yellow build as CGB-enhanced, and modern emulators such as SameBoy support the appropriate Game Boy Color palette behavior.

If you prefer the classic look, you can also experiment with:

Original Game Boy presentation
Super Game Boy presentation
Game Boy Color presentation

This is mainly visual.

It should not fundamentally change the Yellow Advanced storyline.

Best Emulator Settings for Pokémon Yellow Advanced 2019

Setting	Recommendation
System	Game Boy / Game Boy Color
Preferred display	Game Boy Color
Windows	SameBoy / BGB / mGBA
macOS	SameBoy / mGBA
Android	Accurate GB/GBC emulator
iPhone/iPad	SameBoy / Delta
Save type	Automatic/default
RTC	Not required
Normal in-game saves	Yes
Save states	Secondary only
Fast-forward	Optional
Save backups	Recommended

Does Pokémon Yellow Advanced 2019 Need RTC?

No.

Pokémon Yellow does not use the Generation 2-style real-time clock found in Gold, Silver, and Crystal.

Yellow Advanced is based on Yellow rather than Crystal, and I found no documentation indicating that it adds a persistent RTC requirement.

That means you do not need to worry about:

Real-world day/night cycles
RTC batteries
Clock-file migration

for normal Yellow Advanced installation.

Your emulator mainly needs:

Reliable Game Boy emulation
Battery-save support

Can Pokémon Yellow Advanced Run on Real Hardware?

Potentially, yes.

The hack is based on Pokémon Yellow and remains a Game Boy-family ROM.

A compatible flashcart or reflashable cartridge would need to support:

The finished ROM size
Normal Pokémon Yellow save hardware
Game Boy / Game Boy Color operation

Before beginning a real-hardware playthrough:

Start the game.
Make an in-game save.
Power the system fully off.
Turn it back on.
Confirm Continue appears.
Load the save.

If the save survives:

your basic hardware configuration is working.

How to Update Pokémon Yellow Advanced 2019 Safely

For most players, there is no active update cycle to worry about.

I could not verify a release newer than the completed 2019 project.

That means if you are installing Yellow Advanced today:

install the completed 2019 build and keep it.

However, old files and mirrors can still create version confusion.

If You Find a “Newer” Yellow Advanced Download

Before updating:

check whether it actually comes from:

ericgall23
The original PokéCommunity thread
A creator-approved project source

Do not assume a file labeled:

Yellow Advanced 2024

or:

Yellow Advanced v2

is official.

The verified project still traces back to the 2019 creator release.

Step 1: Make a Normal Save

If you are changing Yellow Advanced builds:

make a normal in-game save first.

Then completely close your emulator.

Step 2: Back Up the Battery Save

Locate your save.

For example:

Pokemon Yellow Advanced 2019.sav

Make a copy:

Pokemon Yellow Advanced 2019 BACKUP.sav

Step 3: Keep Your Old ROM

Never delete the ROM that created your working save.

Keep:

Old ROM
Old save

together.

Step 4: Patch a Fresh Pokémon Yellow ROM

If a legitimate newer patch ever appears:

use:

clean Pokémon Yellow + new patch

Do not apply the new patch onto:

your existing Yellow Advanced ROM

unless the creator specifically instructs you to.

Step 5: Test a Copy of the Save

I could not find an official Yellow Advanced save-migration guarantee.

Therefore:

use a duplicated .sav.

Check:

Party
PC Pokémon
Items
Badges
Pokédex
Map location
Story progression

Step 6: Save Again

Make another normal in-game save.

Close the emulator.

Restart.

Verify your progress.

Keep your old backup.

Do Not Update With a Save State

Save states capture the running emulator and old ROM’s internal state.

They are less portable than a normal Pokémon battery save.

For moving between ROM versions:

use the normal .sav

rather than relying on a save state.

Can I Move a Vanilla Pokémon Yellow Save Into Yellow Advanced?

I would not assume compatibility.

Yellow Advanced modifies enough gameplay data that there is no reason to risk your only retail/vanilla Yellow save without explicit creator documentation.

Even if a vanilla save loads, modified:

Maps
Encounters
Events
Items
Pokémon data

could produce unexpected behavior.

Start a new Yellow Advanced game unless you have a backup and intentionally want to experiment.

Can I Move a Pokémon Yellow 151 Save Into Yellow Advanced?

No compatibility guarantee exists.

Treat Yellow 151 and Yellow Advanced as separate games.

Yellow 151 intentionally stays much closer to vanilla Yellow and focuses on Pokédex completion, while Yellow Advanced makes broader changes.

Keep separate saves.

Common Pokémon Yellow Advanced 2019 Installation Problems

“The Patch Won’t Apply”

First check the base ROM.

Expected English Yellow SHA-1:

cc7d03262ebfaf2f06772c1a480c7d9d5f4a38e1

If the hash differs, possible causes include:

Japanese Yellow
Prototype/beta Yellow
Another hack
Modified ROM
Bad dump

Use clean English retail Pokémon Yellow.

“What Patch Format Is Yellow Advanced?”

The current indexed primary-source material does not expose the original attachment filename/extension clearly enough for me to verify it.

Use the file contained in the actual project archive.

Match your patcher to its extension.

Do not guess.

“Can I Just Use Lunar IPS?”

Only if the actual patch is:

.ips

If it is a different format:

use a compatible patcher.

A multi-format tool is safer when documentation is old.

“My Emulator Won’t Open the Patch”

That is normal.

Patch files are not playable ROMs.

You must:

Combine the patch with Pokémon Yellow.
Create a finished ROM.
Open that ROM in your emulator.

“Can I Rename the Patch to .gb or .gbc?”

No.

Changing the filename does not apply the patch.

“Normal Pokémon Yellow Starts”

You probably opened your clean base ROM instead of the patched game.

Keep files clearly named:

Pokemon Yellow CLEAN.gbc

Pokemon Yellow Advanced 2019.gbc

Open the second one.

“How Do I Know the Patch Worked?”

Look for Yellow Advanced-specific changes.

Secondary documentation identifies features including:

New protagonist sprites
Inverse battles
Realms
Updated Pokémon Centers
New dialogue
B/W-style Repel behavior

If everything appears identical to untouched Pokémon Yellow:

recheck which ROM you launched.

“The Game Looks Like a GBC Game Even Though Yellow Is a Game Boy Game”

That is normal.

The standard English Pokémon Yellow release includes Game Boy Color enhancements, and the recognized retail ROM is identified as CGB-enhanced.

“My Save Disappeared After Renaming the ROM”

Check your filenames.

Many emulators match:

Pokemon Yellow Advanced 2019.gbc

with:

Pokemon Yellow Advanced 2019.sav

If you rename only the ROM:

your old .sav may still exist under the previous filename.

Do not start over until you look for it.

“My Save State Won’t Load in Another Emulator”

That is normal.

Save states are usually emulator-specific.

Use the game’s normal battery save if you plan to switch between:

SameBoy
BGB
mGBA
RetroArch
Mobile emulators

“Does Yellow Advanced Have All 151 Pokémon?”

The question-bank groups Yellow Advanced together with Yellow catch-em-all hacks, but the sources I verified for this specific article do not give me strong enough primary documentation to state a precise “all 151 catchable” rule for Yellow Advanced itself.

Do not silently transfer Yellow 151’s feature list onto Yellow Advanced.

For exact Pokémon availability, use our Pokémon Yellow Advanced Pokémon locations guide.

“Does Yellow Advanced Have Inverse Battles?”

Yes.

Current secondary documentation lists both:

Inverse wild battles
Inverse Trainer battles

as Yellow Advanced features.

“What Are Realms?”

The project feature list mentions:

Realms

as additional Yellow Advanced content.

For their exact locations, purpose, and progression requirements, use our Pokémon Yellow Advanced walkthrough rather than assuming they work like any other hack’s optional areas.

“Does Pokémon Yellow Advanced Have Eight Gyms and the Elite Four?”

Yes.

The completed project documentation lists:

Eight Gym Leaders
Elite Four

as part of the game.

“Does Pokémon Yellow Advanced Have a Female Player Character?”

The documented feature list includes new:

male/female protagonist sprites.

That is one of the visual changes you can use to distinguish the hack from vanilla Yellow.

“Is Pokémon Yellow Advanced a GBA Hack?”

No.

Some ROM-download sites incorrectly label it as “GBA” even while simultaneously listing its base as Pokémon Yellow.

Pokémon Yellow Advanced 2019 is a hack of:

Pokémon Yellow for the Game Boy/Game Boy Color family.

Do not look for a .gba FireRed-style version.

“Does Yellow Advanced Need a BIOS?”

Normally, no external BIOS should be necessary when using a modern emulator such as SameBoy.

SameBoy includes open-source boot ROMs and supports normal Game Boy/Game Boy Color software.

“Can I Use Delta?”

Yes, as a general Yellow-compatible iOS emulator.

Delta officially supports Game Boy (Color) games.

Patch the game before importing it.

“Can I Use SameBoy?”

Yes.

SameBoy supports Game Boy and Game Boy Color games plus battery saves and is an excellent choice for Yellow-family ROM hacks.

“Can I Use mGBA?”

Yes.

mGBA officially supports Game Boy and Game Boy Color software in addition to GBA.

“Does Yellow Advanced Need RTC?”

No special RTC requirement is documented.

Pokémon Yellow predates Gold/Silver/Crystal’s real-time clock.

“Is Yellow Advanced Still Being Updated?”

I found no newer creator-approved release replacing the completed 2019 project.

Current catalogs still list it as the completed 2019 hack.

How to Verify That Pokémon Yellow Advanced 2019 Installed Correctly

Verify the Clean Base First

Before patching:

SHA-1: cc7d03262ebfaf2f06772c1a480c7d9d5f4a38e1

Verify the Project

The creator/project should be:

ericgall23 — Pokémon Yellow Advanced 2019

Check the Opening and Graphics

Look for differences from ordinary Yellow.

The documented project features include new protagonist graphics.

Check the Pokémon Centers

Yellow Advanced’s feature list specifically mentions changed/improved Pokémon Centers.

Check the Repel System

The project includes a Black/White-style Repel system.

Watch for Inverse Battles

Inverse wild and Trainer battles are documented features.

Test Your Save

Save through the normal Pokémon menu.
Close the emulator completely.
Reopen the game.
Confirm Continue appears.
Load your save.
Save again.

If:

Yellow Advanced-specific content appears
The game does not behave exactly like vanilla Yellow
Your normal battery save survives a restart

your installation is ready.

Where should I go after installing Pokémon Yellow Advanced 2019?

Once the game is running correctly, read our Pokémon Yellow Advanced / Yellow hacks beginner guide.

Because Yellow Advanced changes more than simple Pokémon availability, a vanilla Pokémon Yellow guide will not always answer questions about:

Inverse battles
Realms
Modified Pokémon Centers
Changed dialogue
Updated encounters
New progression details

Also see our:

Pokémon Yellow Advanced / Yellow hacks main guide

and:

Pokémon Yellow Advanced / Yellow hacks latest version guide

for the broader Yellow-hack cluster and current release status.

If your main goal is simply completing the original Pokédex without trading, compare it directly against our Pokémon Yellow 151 guide before choosing your long-term playthrough.

Suggested article screenshots: Use your own Pokémon Yellow Advanced title/gameplay screenshot, a patching screenshot showing the verified clean Pokémon Yellow base, and/or the official PokéCommunity project page. Because the original patch extension is difficult to verify from currently indexed material, a screenshot of the creator’s actual patch archive or README would be especially useful when publishing this guide.
