PicoDrive 3DS compatibility table can be found on this page. Note that CD games run a little slower (you should enable 1-2 frameskips) on an Old 3DS, but it runs very well on a New 3DS. You can quit the emulator to your homebrew launcher/your CFW's home screen in the game menu. It can play Master System, Mega Drive games and Sega CD games, and 32X games.

This emulator uses the same user interface as VirtuaNES for 3DS, TemperPCE for 3DS and Snes9x for 3DS. You can place all three BIOS in the bios folder.

bios_CD_E.bin, for the respective regions.

If you have the CD ROM BIOS, place them in sdmc:/3ds/picodrive_3ds/bios/.

3DSX - Copy picodrive_3ds.3dsx, picodrive_3ds.smdh and picodrive_3ds_top.png into sdmc:/3ds/picodrive_3ds/.

Install picodrive_3ds.cia with your favorite CIA installer.

CIA - Copy picodrive_3ds_top.png to root of your SD card.

The screen rendering is done completely using the original PicoDrive's ARM processor-optimized renderer. It sounds ok for many games, except for those that use high-pitched notes or sound samples. But the 2nd core on the Old 3DS is unfortunately not fast enough to generate the FM synthesized music at a full 44100Hz, so sounds are generated at 30000Hz on an Old 3DS. So this port heavily relies on the 3DS's 2nd core to emulate the FM synthesized music for the YM2612 FM chip to achieve 60 FPS. This is a port of notaz's PicoDrive emulator to the Old 3DS.Īlthough PicoDrive is already highly optimized for ARM processors, if ported as is, it still doesn't run full speed for all Mega Drive games on the Old 3DS/2DS, as it's evident in the RetroArch's version.
