i doubt people check oldest thread and since wanted to ask about gbarunner too tought bump was fine

 

on the psp gba emulator some games doesnt work or crash sadly and even some cht cheats doesnt work too

 

my 3ds is an old one and mgba is slow and not seen cheat support in this emulator

 

what you could do is use the official gba vc, create a .sav, export your save file, download an android gba emulator, copy the .sav on the droid, use whatever cheats you want, and then import the save back.

 

You might wanna follow the gbarunner2 thread. There was some talk about cheat code support in the future.
Though it gonna take a while because Gericom, the main developer of gbarunner2 is busy with his study. Development time is limited to 1-2 hour a day.
