The last thing you will need is gba_bios.bin. Next, download game_config.txt from here and a sample homebrew application here to make sure everything is set up right before you run regular GBA ROMs. cia manager such as FBI, BRM, or DevMen to install it. cia from here and place it anywhere on your SD card. Once you have gba_bios.bin, place it either in the root of your SD card or in /gba. A proper GBA bios dump is preferred, Normatt's bios has shown issues with some games. You can either dump this/find this online, or you can use Normatt's open source GBA bios here. You can also grab the smdh here and give it the same name and place it in the same directory as the 3dsx. 3dsx here and rename it/place it in sd:/3ds/. However, if you encounter bugs let me know the game name and when the bug occurs so I have games to test against while fixing bugs.įirst, grab the. Once again, this is very much a work in progress and extremely buggy, but the bugs will be fixed and the emulator refined with time. You can find the source code for CitrAGB on my GitHub here. Y is bound to select, and X currently exits back to the homebrew menu This will increase emulation speed dramatically.Ī, B, Start, Select, L, R, and the D/C-Pad all map out to their rightful GBA buttons. In the future I also plan on hopefully porting gpsp's dynrec CPU to be able to work on the 3DS as well, once smea updated ninjhax to allow developers to set RAM pages executable.

But, on the plus side, many games that do run actually run fairly well, around 50% speed in optimal cases, or as low as 20% if the game uses extremely inefficient idle loops. Flipping the screen to it's proper orientation did a bit of damage which might take a bit to get fixed up, and a lot of things still need implementation. As of now, compatibility is technically on-par with whatever gpsp's interpreter is able to handle, however, due to the nature of the port some games will not run or crash on particular parts.
