additional information
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. Update by Machone: This seems to be related to the main CPU speed. If you underclock or overclock the z80 processor by just 1%, the problem goes away. The current speed of the z80 in MAME is 3.072mhz, so perhaps this is wrong and should be set at 3mhz? pisces095u6gre Thenasty / Machone (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??). 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.
  • 0.28: Mike Balfour added hiscore save in Pisces.
  • 0.18: Nicola added some lousy noise to Pisces.
  • 0.06: Nicola Salmoria added star background in Galaxians & co. The way Nicola calculate it is probably not correct, anyway it looks reasonable.
  • 0.05: Nicola Salmoria added Pisces (correct colors, limited sound). This game runs on a modified Galaxians board. Only one sound channel is emulated and the game has no star background.
Other Emulators:
  • GalEMU
  • Sparcade
  • VAntAGE
