Game's rom.

MAME Info:

0.34b7 [Thierry Lescot]

0.34b6 [Nicola Salmoria]


- 0.143u6: Various Wiz driver fixes [Tafoid]: Fixed cocktail controls for Scion and clone. Took ROM_LOAD_OPTIONAL out of ROM_START that uses the audiocpu rom from scionc for scion. The original Scion audiocpu is not emulated correctly, is a known issue, and was only covered up by the use of this other dump from scionc. Removed audiocpu rom 6.9f.

- 0.95: Aaron Giles fixed crash in Scion.

- 0.72u1: Added Discrete sound and cpu2 rom ($0 - optional sound rom). Changed visible area to 240x224 and 'Unknown' to 'Unused' dipswitches.

- 12th August 2003: Acho A. Tang re-submitted framework for sound effects in Scion and Stinger.

- 0.37b12: Changed clock speed of the 2x AY-8910 to 1536000 Hz.

- 0.34RC1: Zsolt Vasvari added high score saving to Scion.

- 0.34b8: Better colors in Scion (still not accurate) [Dick Millikan]. Added color proms ($0, 100, 200). Changed description of clone to 'Scion (Cinematronics)'.

- 0.34b7: Thierry Lescot added Scion (Seibu Denshi 1984). Renamed (scion) to (scionc). scion has some constant background noise. scionc doesn't. This might be due to a bad ROM.

- 0.34b6: Nicola Salmoria added Scion (Cinematronics 1984).
