THE SOUND OF YOUR COLLECTION
Original cartridge soundtracks, in a jukebox built around the games you own.
Import supported cartridges as albums, save favourites, revisit recent tracks and let the visualiser follow the music. Choose Atari ST or Mega Drive inside the jukebox, independently of your homepage. Starting in SemaDrive selects its soundtrack library first; if music was stopped when you quit, it stays stopped on your next launch.
All 19 profiled games now support cartridge soundtrack import, with 486 track selections. Sonic 1–3, Sonic & Knuckles, Sonic 3 & Knuckles, Golden Axe I/II, Streets of Rage 1–3, Shinobi III, Gunstar Heroes, Thunder Force IV / Lightening Force, Bloodlines, Rocket Knight Adventures and Aladdin join OutRun, Altered Beast and Road Rash II.
The level display is illustrative. During gameplay, supported profiles offer independent music and effects levels. Jukebox imports and audio controls have separate support lists. No games or soundtracks are bundled; this page plays no audio.
FAMILIAR, DOWN TO YOUR FINGERTIPS
Session and Settings share the same layout across machines. Save, rewind, restart, tune the picture, or adjust your controller without learning another frontend.
