MAME Info:
0.88u4 [David Haywood]
WIP:
- 0.100u2: Aaron Giles updates the Sega C2 driver and got Twin Squash working. Replaced 8-way Joystick with Dial and 1 button. Added dipswitches 'Buy In', 'Seat Type' and 2x 'Unknown'.
- 0.88u4: David Haywood added Twin Squash (Sega 1991). Protection issues.
- 9th November 2004: David Haywood - It's amazing what turns up when you least expect it... the BDT pulled some roms for Sega's Twin Squash out of their hats, it runs on C2 hardware but appears to have a few issues with protection at the moment. I'm unlikely to be able to deal with the protection issues myself, but hopefully somebody else can.
