There may or my not be a post on this , I have looked. A side from my above posts, but why can't running GBA games from a R4 card be better. I 've tried several setups but most dont work, or work poorly. I am puzzled why they make good working emulators for ios and android, but when it comes to running through a R4 card on a Nintendo console is fair at best. What is the secret. the SD card on dsi with GBARunner works wells except for Pokemon Emerald which who knows why that does not work. Can GBA runner work on a R4 setup up , or what should I do. Thanks in advance
