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

[MarioKartFan]

This is an insanely old thread. GPSP dynarec was fixed. The Retroarch core is excellent on any New 3DS model.

Also, we have:

• mGBA emulator (cheats option possible, but dunno if already implemented) for NEW 3DS/2DS
• GBA VC injection (cheats possible with this, afaik) or open_agb_firm (no cheats for now) for OLD 3DS/2DS

All above options much better than GBARunner2 hypervisor (no cheats for now, neither) for 3DS/2DS. However, for DS or DSi consoles, GBARunner2 is a great option to run gba games

I still don't understand how to use cheats even on the latest version of mGBA on my N3DS. Would someone, please, explain it to me like I'm a five-year-old?

So, I set-up RetroArch on my n3ds. The gpSP core runs amazingly well, and even the fast forward works great. It, also, comes with built-in cheat support, which I'm sure the OP will like. If it runs this smoothly on my n3ds, even the fast forward, I'm sure it can run well on old 3ds. The only problem I've run into is that it doesn't support encrypted cheats, and encrypted codebreaker cheats is the only type that a certain website creates .cht files in. But the mGBA Core supports cheats, too—including encrypted codebreaker cheats! The only problem with THAT emulator is that it's seemingly a bit slow, and I'm not familiar with all the various settings to make it run smoother yet, but it's not that bad; just slightly slower in sound, I guess.

ANYWAY, OP (Riktor, or something?), RetroArch is the way to go, my man. This link explains things better than I ever could:

Hope this helps. Oh, and it definitely supports cheats. Google is your friend; there's a mega archive for .cht files for, like, 35 or so different systems on Reddit, and you can find it with a simple Google search. So you're aware, don't try to send the files through andFTP. Lol…
