  • 0.27: Mirko Buffoni and Tatsuyuki Satoh provided a preliminary driver for Xevious (Atari 1982), Xevious (Namco 1982) and Super Xevious (Namco 1984) (not working yet). To start the game, press ALT (sorry - will be fixed in a future release). The sound works, but at the beginning it plays and endless sequence of "coin inserted" sounds. That's because it believes you have inserted 80 coins. After playing for a while, it becomes normal.
  • 0.23: Nicola Salmoria and Mirko Buffoni added a very preliminary driver for Xevious.

- TIPS AND TRICKS -


* Secret Message : The bootlegger has included the trick for generating a message right at the beginning of the game. As soon as Solvalou appears, move to the far right edge of the screen and begin bombing constantly. Continue bombing until the first set of attacking rings is very close to you and then shoot the rings. The message 'Dead copy making copy under Namco program.' will appear on the screen.
