Finally our dream has come true, let's show them one GBA emulator for DS and DSi without special flascard and / or slot-2 , for now, has no sound support good speed, but the emulation can be improved with the CycloDS iEvolution mode because it supports DSi, as this emulator is also scheduled to mode DSi. Participate in the Homebrew Bounty . The project is alive, could be further improvements soon.
