Before entering one, check whether it is listed for FireRed Rev 0 (v1.0) or Rev 1 (v1.1), then select the matching code format in your device or emulator. Back up your save and enable codes cautiously.
Before using a FireRed cheat code
“FireRed cheat” does not identify one interchangeable code set. Some codes are listed for a specific game revision and memory layout; a code for one revision may fail or affect the wrong data on another. The version comparison guide explains the Rev 0/v1.0 and Rev 1/v1.1 distinction: Pokémon FireRed version and cheat guide.

Code format matters too. References label entries as GameShark, Action Replay or CodeBreaker, and an emulator may require you to choose the corresponding type. The FireRed Rev 1 index at GameHacking.org lists GameShark Advance/Action Replay codes, while other references include different formats and revision examples. A master or enabler code is not universal: follow the instructions attached to the particular entry and setup.
- Check the revision: use an entry explicitly listed for your game version.
- Match the format: select the code system the entry specifies.
- Protect your save: make a separate backup before experimenting.
- Start with one code: multiple simultaneous cheats can freeze or crash the game.
What kinds of codes are in the lists?
The referenced collections include codes for items, money, movement, encounters, battles and progression. These are categories of listed codes—not a claim that every entry works on every revision, emulator or device. The labels below describe the kinds of effects readers may be looking for; check the individual source entry for its code, revision and format.

| Effect | Examples of listed code labels or uses | What to check |
|---|---|---|
| Items | “Unlimited Rare Candy in PC”; “Master Ball Cheat” | Revision, code format and any entry-specific activation instructions. |
| Money | Money or currency modifiers | Whether the entry is for your revision and code system. |
| Movement | “Walk Through Walls”; biking over water | Use extra caution around scripted events; movement cheats can cause problems. |
| Encounters | “No Random Battles”; “Wild Pokemon Modifier” | Some references report disputed results for particular encounter-related codes. |
| Battle | Battle changes and skipping trainer battles | Do not assume a listed effect has been verified on your setup. |
| Progression and Pokédex | Pokédex edits, including a Complete Pokédex listing | The libretro Rev 1 file labels its Complete Pokédex cheat buggy and advises saving first. |
The libretro database file named for Pokémon FireRed Version (USA, Europe) Rev 1 contains 27 entries, according to that file as accessed in 2026. That is a count of entries in one file—not a count of confirmed working codes or proof of broad compatibility. Other indexes collect entries across labels and formats, so a “40+” collection should be understood as a compilation rather than a promise that all codes work together or on one revision.
How to enter cheats on a GBA emulator
- Open the emulator’s cheat menu. Menu names and locations vary by emulator.
- Add a new cheat. Give it a recognizable name, such as “Rare Candy,” if the emulator asks.
- Choose the listed code type. Select GameShark, Action Replay or CodeBreaker to match the entry; do not convert formats by guesswork.
- Enter the code and save the entry. If the code listing specifies a master or enabler code, follow that listing’s setup rather than adding a generic one.
- Enable only that code first. Load or resume the game and check whether the described effect occurs. A successful save or accepted entry in the menu does not establish that the code is compatible.
- Disable the code if the game behaves unexpectedly. Restore your backup if needed, then re-check revision and format before trying anything else.
These are general steps, not emulator-specific menu paths: the reviewed emulator guide notes that labels differ. The PokemonCoders Fire Red cheat guide gives the general add-select-format-save-enable process and includes individual code listings.
Rank #2
- This renewed game will not come with the original case or manual; cartridge only. It has been cleaned, tested, and is in nice condition.
Using codes on original GBA hardware
On original hardware, GameShark or Action Replay devices are an optional way to enter supported codes. The references do not establish that every device version accepts every listed code, so confirm the exact device and game revision compatibility before relying on a listing. Emulator users can instead use the emulator’s built-in cheat menu where available.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Why a code may fail—or cause trouble
- Wrong revision: a code aimed at Rev 0 may not suit Rev 1, or vice versa.
- Wrong format: a GameShark/Action Replay entry may not work if entered as CodeBreaker, or the reverse.
- Missing entry-specific setup: some cheats require a master or enabler code, and setup differs by code and system.
- Conflicting cheats: stacking codes can cause freezes or crashes.
- Risky effects: walking through walls during scripted events can disrupt progression; save corruption is also a risk.
- Uncertain reports: a code appearing in a database is not proof it works on every setup. The updated PokemonCoders page includes user reports disputing a catch-rate code despite describing a hand-testing process.
For ROM hacks, do not assume an original FireRed code will work. Hacks can change memory addresses or item IDs; the version guide recommends using a guide made for the specific hack.
