0.10 [Nicola Salmoria, Mirko Buffoni, Ivan Mackintosh, Edward Massey, Pete Rittwage]


- To see the color test, keep T pressed then hit F2. Insert a coin to proceed to the convergence test. Press T and F2 again to exit.


- Clone Centipede (bootleg set 1 / set 2) uses a AY8910 for sound, all other uses Pokey sound.


- 0.108u1: Fixed rom names.

- 0.104: Fixed centiped0103u3ora bug (time delay to register coins).

- 0.97u5: Aaron Giles fixed sprites rotating in cocktail mode.

- 0.92: Highwayman added prom ($0 - sync-prom).

- 0.84u5: Stefan Jokisch renamed (bootleg set 2) to Centipede (bootleg) and Centipede (bootleg set 1) to Caterpillar. Added new gfx1 rom ($800) to Caterpillar.

- 0.78u1: Stefan Jokisch added prom ($0 - unused) to clone Millpac.

- 0.68: Chris Hardy added clone Millpac (1980 Valadon).

- 15th May 2003: Chris Hardy added Millpac to the Centipede driver.

- 19th November 2002: Stephane Humbert added a clone called Caterpillar to the Centipede driver.

- 0.62: Added clone Centipede (1 player, timed).

- 20th July 2002: Zsolt Vasvari added a timed version of Centipede to the Centipede driver.

- 0.60: Added clone Magic Worm (bootleg). Changed palettesize from 20 to 8 colors.

- 14th April 2002: Aaron Giles added a bootleg called Magic Worm to the Centipede driver.

- 15th April 2002: Aaron Giles merged the Centipede, Millipede, Warlords and Qwak prototype drivers because they were similar.

- 2nd September 2000: Brad Oliver abstracted the dirty handling from Centipede and sped up Atari Tetris.

- 27th February 2000: Nicola Salmoria fixed a Centipede palette bug.

- 0.36RC1: Nicola Salmoria fixed a rounding error in IPF_CENTER handling which caused problems with Centipede. Note, however, that it would be advisable to not use IPF_CENTER at all for trackball/dial inputs, since this is probably not how the hardware works in reality. For the same reason, also removed the "clip" parameter from the PORT_ANALOG() macro.

- 0.36b11: Zsolt Vasvari added clone Centipede (bootleg set 2).

- 29th November 1999: Zsolt Vasvari added another Centipede bootleg romset.

- 0.35b2: Zsolt Vasvari added Centipede (bootleg) with AY8910 instead of Pokey.

- 0.33b1: Brad Oliver added clone Centipede (rev 1) and fixed service mode in Centipede. Changed the 6502 emulation to disable interrupts on a reset. Not sure if this is the correct behaviour, but Centipede needed it for the service mode to work. Nicola Salmoria fixed colors in Centipede, including service mode multiplexed color test.

- 0.27: Thanks to the precious information on the Pokey random number generator provided by Eric Smith, Hedley Rainnie and Sean Trowbridge, some problems with Centipede (start with 18 credits) and Tempest (hang after level 13) are now solved.

- 0.26a: Mirko Buffoni worked with the wrong source, now everything is back to normality in Centipede.

- 0.26: Patrick Lawrence did a great work adding trackball support to the main core system. Trackball is enable with -trak parameter. Trackball support has been added to Centipede and Reactor.

- 0.14: Hiscore save in Centipede.

- 0.12: Sound in Centipede, through Ron Fries' POKEY emulator.

- 0.10: Nicola Salmoria added Centipede (Atari 1980). This is the first 6502 game supported by MAME. Nicola currently use Marat Fayzullin's engine. Memory map comes directly from the Atari schematics (1981). Centipede information taken from Centipede emulator MageX by Ivan Mackintosh. Issues: What is the clock speed of the original machine? I'm currently using 1Mhz, Nicola don't know if the game runs correctly. The game awards you 18 credits on startup.
