gba emulator with cheat support for cfw 3ds or at least for ds flashcart

I don't think GBARunner2 has cheats support but I may be wrong. You could use gpSP though.

 

Yeah, gpSP isn't perfect. You could try mGBA if you have a n3DS.

 

GBARunner2 isn't great anyway. The only method that runs well and has good compatibility is injection.

 

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 can use GBAATM to cheat in anything https://gbatemp.net/threads/gba-auto-trainer-maker-gbaatm.99334/
The download links are dead, may have to contact @cracker to get him to send you a link or upload it to the GBAtemp download center.

 

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.

It´s in the Nintendo DS homebrew section.

 

Any news for the topic? Cheats on mGBA would be a great feature...

 

I’m just gonna mention that retroarch has a gpsp core for 3ds, and it has cheat support

 

Even if you find one with cheat support, no "regular" GBA emulator is going to run well enough on old3DS. Maybe if the dynarec in gPSP was ever fixed. Your only option is to hack the rom and either inject into VC or use GBARunner2.

 

Check the quick menu.
If retroarch doesn't work well for you, look for "trainer" patches that let you select the codes before the game starts, and then inject them into VC

 

Just install twilightmenu++ and gbarunner2 comes built-in. Its a DS/i program so it runs great on old3DS. There's no built-in cheat function though, so you're again looking at hacking roms.

 

There is a standalone one as you can run it from a NDS or DS Lite. If your running this one you need the file gbarunner2*****.nds. Launch it as you would any NDS rom. The reason for the * is there is an Arm7 and Arm9 version (ie gbarunner2arm7.nds).

The GBA had an Arm 7 processor and DS Lite Arm 9 (and an Arm7). Basically you may not be able to run the rom and the game on the arm7 processor (Its like running with concrete boots).

In most cases both versions will work.... but get them both and if a game isn't working on one try the other.

There is also a 3DS version.... but that's the one with twilight so your games will need to be on the main 3DS SD card.... and not the carts Micro SD Card. Hope that helps.
