MAME Info:

0.61 [Zsolt Vasvari]


WIP:

- 0.140u2: Atari Ace take some driver_device classes of espial/marineb/zodiack (common code duplicated) that cover multiple drivers and split them so that each driver gets their own driver_device class. In most cases, these drivers got entangled because of audio/mcu code that was shared between multiple drivers.

- 0.136u3: Stephane Humbert fixed dipswitches and inputs (after verification of the Z80 code) for Net Wars. Added dipswitches 'Difficulty', 'Reset on Check Error' and 3x 'Unused'.

- 0.135u1: Fabio Priuli added driver data struct to Espial driver.

- 0.133u5: hap fixed access violation in Net Wars.

- 0.131u1: MooglyGuy audited code, added savestate support to Net Wars and merged memory maps in the Espial driver.

- 0.105u4: Fixed prom names.

- 0.77: Added 'Unknown' dipswitch.

- 0.61: Zsolt Vasvari added Net Wars (Orca 1983 (Esco Trading Co license)).

- 11th June 2002: Zsolt Vasvari added Net Wars to the Espial driver.
