MAME Info:

0.59 [Mike Coates]

0.05 [Nicola Salmoria, Robert Anschuetz]


Bugs:

- Sometimes there is a square block on the bottom right in attract mode, or gameplay. Thenasty (ID 00448)

- When you warp after the first level, the noise completely overrides the music. Robbbert (ID 01594)


WIP:

- 0.99u1: Pierpaolo Prazzoli added clone Omni.

- 0.59: Mike Coates added Pisces (Subelectro 19??). Added 'Unused SW 0-3' dipswitch. Renamed (pisces) to (piscesb).

- 16th March 2002: Mike Coates added the Subelectro version of Pisces to the Galaxian driver, it appears to have better colors than the current version.

- 0.34b1: Added color prom pis_l6.bin (very close to Galaxian).

- 0.28: Mike Balfour added high score saving to Pisces.

- 0.18: Nicola Salmoria added some lousy noise to Pisces.

- 0.06: Star background in Galaxians & co [Nicola Salmoria]. The way I calculate it is probably not correct, anyway it looks reasonable.

- 0.05: Nicola Salmoria added Pisces (correct colors, limited sound). Game is playable with accurate colors and limited sound. This game runs on a modified Galaxians board. Control: Arrows = Move around and CTRL = Fire. Known issues: Only one sound channel is emulated, and I'm not sure it's correct. No star background. What do the dip switches do?

- 31st July 1996: Paul Swan and Sean Riddle supported Pisces (bootleg).
