Xevios © 1983 Watson.
This game is a bootleg of "Xevious". It has different explosion sound than the original Xevious.
The titlescreen says '1980' but the game was certainly released in 1983.
* Secret Message : The bootlegger has included the trick for generating a message right at the beginning of the game. When Solvalou appears, move to the right edge of the screen, wait a few seconds and drop a single bomb as soon as the music changes (after the long note). The message 'Dead copy making copy under Namco program.' will appear on the screen.
