Picodrive is a popular emulator for a wide variety of game consoles from the 8 to 16bit generation. It also supports a peripheral add-on that Genesis Plus GX does not. Both cartridge and CD-ROM games should be supported. It also works well with many of RetroArch's advanced features, such as real-time rewind, runahead latency reduction, cheats and RetroAchievements. It is also one of the faster emulators of its type.
