Key points

Port of the Sega CD/Mega-CD Special Edition of the game which contained an exclusive level, a few extended levels, alternate endings, and CD quality music.
Running the game properly on modern Windows will require a few steps and workarounds, even if it does run mostly fine out of the box. See Issues fixed.
Runs on par with the Mega Drive/Genesis version; far faster and smoother than the DOS PC port.
Improved visuals and sound effects over the Sega CD/Mega-CD version.
A couple of short audio cues were removed, replaced by lower quality versions, or are incomplete; e.g. the victory and failure music that plays at the end of Andy Asteroids, the voice at the title screen, and the bad ending speech.


Source DRM Notes Keys OS
Disc check (requires the CD/DVD in the drive to play)
Runs directly off of the disc, uses Redbook audio for music. Can run off of your hard drive if you copy the files over, but the disc is still required for DRM and music.
