Sega Genesis (Mega Drive) Emulator

Genecyst is a Sega Genesis (Mega Drive) emulator for Chrome OS, Chromium OS. It's capable of running 1278 game ROMs on 1539, 83% of the whole console catalog. It is not distributed with game ROMs. Neat features: - Multiple save states and battery backed ram. - Game Genie codes. - Save snapshots. - Wave output loggable. Lacks: - Shadow/highlighting effects. - Interlaced modes. - The emulation of the 6-button controllers is only a guess, but it seems to work for most games. 6-button Genesis controllers can be enabled from the Settings menu. - Raster effect emulation is by default off because it's a bit buggy. Raster effect can be enabled from the Settings menu. Examples of games that need raster effects are: ToeJam & Earl, Ghouls'n Ghosts, Street Fighter 2 Turbo and Michael Jackson's Moonwalker. The "Force display" menu option is only needed for a few games. The "DMA fix" option fixes Mega man the Wiley wars.

Doesn't seem to work for me. Every time I try to load up a rom, it just loads a black screen then fades away.

Try Sonic the hedgehog first! This emulator isn't capable of running 100% of roms out there, maybe tht's your case!

Additionally I've reduced the CPU usage of about 10% with the last update... A single core machine @1.9Ghz is sufficient for running this emulator at full speed...
