Artwork available


- offtwall, offtwalc: In "service" mode, the menu has lost its color. This makes it so you cannot see what selection is highlighted. Previous versions of MAME do not exhibit this problem. Darkk (ID 00784)


- 0.150: Added 2k offtwall-eeprom.bin EEPROM.

- 0.149u1: Added 'Atari JSA II Sound Board' sound.

- 0.147u2: Initial round of atarigen cleanup/modernization [Aaron Giles].

- 0.146: hap fixed atarivc_eof tag and shortened playfield_upper(15 chars) tag to playfield_up.

- 0.139u3: Aaron Giles moved the old hard-coded EEPROM data out into a file in Off the Wall.

- 0.139u1: Aaron Giles changed atarigen_state to be a base class from which all the related Atari drivers derive their state from.

- 0.135u4: Some more Atari driver shuffling [Aaron Giles]: Added atarigen_init() function which allocates all timers and registers for save states. Updated all drivers to call it. Converted some drivers to use device timers.

- 0.135u3: Aaron Giles converted atari drivers over to using driver_data for the most part. Some shared systems still exist with globals, but this tackles the atarigen module and the variables local to each driver.

- 0.133u1: Renamed (offtwalc) to (offtwallc).

- 25th July 2008: 3D ARCADE - New 3D cabinet model for Atari's Off the Wall from btribble.

- 0.114u2: Aaron Giles and Couriersud added more accurate video timing to most of the Atari 68000-era games. The parameters are from published specs, not derived. The board uses a VAD chip to generate video signals. Changed VSync to 59.922743 Hz.

- 0.114: Couriersud added general save state support to the atarijsa and atarigen modules.

- 26th August 2006: Mr. Do - Added Off the Wall bezel from and Mean Arena. Some of these decent stuff are so-so; some are REALLY good.

- 0.97u4: David Haywood fixed Atari Audio Board II (sndhrdw\atarijsa.c) for games without OKI6295 sound.

- 0.95u3: Removed OKI6295 sound (because of the 0.93 Sound System update).

- 0.93: Added OKI6295 (9037Hz) sound.

- 0.37b15: Changed M6502 CPU2 clock speed to 1789500 and YM2151 to 3579000 Hz.

- 0.36RC1: Changed 68000 CPU1 clock speed to 7159090 Hz, M6502 CPU2 to 1789772 Hz and YM-2151 to 3579545 Hz.

- 0.36b5: Changed input to Dial. Added 'Controls' dipswitch.

- 6th September 1999: Aaron Giles sent in a huge Bally/Sente driver, with Chicken Shift, Gimme a Break, Goalie Hhost, Hat Trick, Mini Golf, Night Stocker, Off the Wall, Rescue Raider, Sente Diagnostics Cartridge, Snacks'n Jaxson, Stocker, Street Football, Toggle and Trivial Pursuit. There are still more games running on this hardware.
