Welcome to GenesisPlus - MorphOS

Genesis-Plus emulates the classic Sega Genesis/Megadrive,
Sega/MegaCD,MasterSystem and GameGear game consoles.

SegaCD support requires a bios file called BIOS_CD_U.bin
in the bios/ directory. SegaCD games must be in bin/cue format.
Select the .cue file to launch the game.

Press TAB key to open save state manager. Save states are
available for Genesis, MasterSystem, GameGear and SegaCD.
