What is Pokemon Ghost Grey?
Pokemon Ghost Grey is a FireRed-based and completed Pokemon ROM hack by joeyzeed. You explore a decayed Kanto in the year 2049. Ghosts have overrun the region and the remaining people are struggling.
You choose Rowlet, Litwick, or Spiritle for your starter Pokemon and your rival is named Summer.
The game has seven gyms and includes over 200 Ghost-type pokemon with 120 original regional variants. The graphics have been completely redonem, it even has voice acting with 130-track original soundtrack.
This is unusual for a GBA ROM hack but you can expect a whole new experience while playing. Pokemon Ghost Grey has physical/special split feature and even newer items.
Do Cheats Work in Pokemon Ghost Grey?
Absolutely, Yes! and a lot more popular cheats we know on FireRed are usable here in this rom hack.
If you know Unbound, Radical Red, Amethyst, they are built using the engine called CFRU (Complete FireRed Upgrade).
CFRU rewrites large parts of a game and heavily modifies them. That’s the reason why there other classic Pokemon FireRed cheats fail on those hacks, including the most favorite Walk Through walls.
Pokemon Ghost Grey is built using a different engine called HexManiacAdvance, a much cheat friendly tool that changes only the ROM’s content but not the underlying memory layout close to vanilla FireRed.
| Cheats Expected to work | Cheats Expected to fail |
| Walk through walls, Master ball, rare candy, shiny encounter, No Pokemon encounters, wild Pokemon modifier, Infinite EXP, Infinite PP, and many more. | Max EV/IV codes and Fast egg hatching |

Cheats That Do Not Work in Pokemon Ghost Grey
Don’t bother with these cheats. These codes fail on Ghost Grey.
| Cheat | Why it fails |
|---|---|
| Max IVs / Perfect IVs | The author of Ghost Grey removed IVs and Hidden Power. All Pokemon have 0 IVs. The code has nothing to change. |
| Max EVs / EV training codes | The same with the Max IV, Max EV is also not available in this game. Pokemon normally don’t gain EVs. |
| Fast Egg hatch | Breeding is not in the game. |
| Have all 8 badges cheat | Ghost Grey only has seven Gym Badges. Using a cheat that gives you all eight badges may cause progress issues or other unexpected problems in the game. We recommend avoiding this cheat. |
| Complete Pokedex | Even in the original Pokemon FireRed, this cheat is known to create issues. Using it in Pokemon Ghost Grey can also mess up your game, leading to incorrect Pokedex data. We recommend completing the Pokedex normally. |
Pokemon Ghost Grey Cheats Not Working? Try This
- Wrong Cheat Type. A cheat when added to a wrong cheat type will do nothing. Cheat type is already provided in every cheat, make sure to follow it.
- Enabled too many cheats. Some emulators keep cheat effects active even after you disable the cheats in the settings. If this happens, disable all cheats and restart the emulator to help clear up any remaining cheat effects.
- Emulator limitations. There are emulators that do not fully support cheating. Double check if your emulator supports Code Breaker and Action Replay/GameShark cheats.
- Pressed the wrong button combination. Some cheats, like “Capture/Steal Trainer Pokemon” and “Run away from Trainer Battles” require button combinations to be pressed to activate them. Check your emulator’s control settings to see which keyboard keys are assigned to each GBA button. If needed, reconfigure the controls so you can press the required combination correctly.
