So i've tried the basic default firmware for the r4 sdhc dual core, and many games are incompatible with it. Booting dsi enhanced games or many others (such as sonic colors) result in a white screen. To fix this, i tried using ysmenu in order to launch any game, which did work. The only issue is that the games that didn't boot before now crash randomly at different points. is there any custom firmware that can fix this issue?
