Just ran the GPSP and Virtual Boy .cia. OMG, they work, but run VERY slowly on the N3DS via EmuNAND FW 9.2. VB gets 7-9FPS running Wario Land.
SNES9x Next gets around 11-16FPS
Genesis Plus GX gets around 16-20FPS
CATSFC gets around 16-30FPS(16FPS In-Game when Playing)
PicoDrive Locks up. Tried a .md File, and I get a Red Upper Screen displaying at 40FPS. Try running a .gen File, and it all locks up needing a Forced Shutdown. One Game I got to run MKII Unlimited Hack gets anywhere from Mainly 26FPS to 50FPS with steady 28FPS during Fights, so basically, it is somewhat Playableish
Nestopia gets about 16FPS..........but only the Left 1/2 of the Screen is visible
A few of the CIAs have the same Unique IDs so if you go to Install all of the, a few are going to get overridden.
