0.61 [?]


- MAME crashes. Scagazza (ID 04259)


- 0.127u4: R. Belmont changed Mach Breakers to use real C75 Namco NB-BIOS, read controls the real hardware way. Replaced pr1data.8k with C75.bin. Added Player and coin slots 3 and 4.

- 0.113u3: Changed description to 'Mach Breakers - Numan Athletics 2 (Japan)'.

- 27th June 2006: R. Belmont - I'm back to disassembling Mach Breakers (it's written in C and uses a pseudo-multitasking system internally so it's a real pain to figure out the flow of control).

- 0.87u3: Phil Stroffolino improved Mach Breakers. Game specific ROZ hacks have been removed.

- 10th September 2004: Guru - Finally got Mach Breakers (Namco 1995) from Japan. Thanks to MAMEWorld donations and several anonymous (private/direct) donations.

- 0.79u1: Phil Stroffolino added a tilemap tile banking feature used by Mach Breakers and added various Mach Breaker-specific hacks for interpretting the ROZ layer registers; these aren't yet fully understood. In particular, the 'Monster Pull' stage is missing a '3d floor'.

- 0.69: MameTesters changed description to 'Mach Breakers (Japan)'.

- 0.68: Brian Troha added Match Breakers (Japan) (Namco 1995).

- 20th March 2003: Phil Stroffolino hooked up the inputs in Mach Breakers, so it's now playable, though with some graphics glitches.

- 0.61: Brian Troha added Match Breakers (Japan) (Testdriver).

- 6th May 2002: Phil Stroffolino fixed the graphics bugs in Mach Breakers, but controls aren't yet emulated so it isn't yet playable.

- 4th May 2002: Brian Troha added Mach Breakers to the Namco NB-1 driver, but Mach Breakers has lots of graphics bugs.
