This takes advantage of the similarities between the DS and GBA hardware to run games sort of quasi-natively, thanks to a lot of pretty spectacular reverse engineering work. Lastly, you may want to look into Gericom's GBARunner2, which is neither an emulator nor using GBA mode, but instead a hypervisor which runs GBA games under TWL (DS/i) firmware on the 3DS.

This should have close to 100% speed and accuracy, besides the occasional game which included special hardware (like WarioWare: Twisted). For one thing, there's GBA Virtual Console (and Virtual Console injections), which just runs GBA games natively on the 3DS in the system's backward-compatibility mode. If you're OK with moving away from emulation, there's a couple more options you can try. Somebody can hopefully suggest an older version that will work OK, I have no idea exactly when it became broken.Īnother gpSP-based emulator is shinyquagsire's CitrAGB, which is no longer in active development but hopefully still works on modern setups. RetroArch includes a gpSP core, but that core has been bugged and crashy/unusable for multiple years now. For better compatibility with certain games, you may instead use the real GBA BIOS, if you have it. Once it setup i was able to get up to 130fps fastforward in Mario Kart, and i was even able to use the rewind feature without much burden to the emulation. You probably want something gpSP-based, since that uses a dynarec to translate code to 3DS assembly in real time, allowing much faster performance (and a fairly significant penalty to accuracy). As of TempGBA version 1.45, an open-source BIOS replacement based on VBA-M's high-level BIOS emulation is bundled in the release archive. gPsp Core is the best, it requires a GBA bios to be placed in Retroarch system folder (or retroarch will crash). Yeah, on an original model 3DS, mGBA will get you nowhere.
