beekonami's Issues

K007232 core

Checklist:

• Commit source files
• Implement writes
• Implement clocks
• Implement counters
  • CNT1
  • CNT2
  • CNT3
• Implement rest of chip (specifics TBD)

K054539 schematics

The K054539, used as the main sound chip in X-Men, Xexex, and a bunch of other Konami arcade games, including the Konami GX line, has no internal schematics or die shot publicly available. In addition, MAME's implementation of this chip doesn't really sound right compared to real hardware.

We need somebody to decap and image this chip, so that it can properly be reverse-engineered.

K053252 schematics

The K053252, used in Overdrive, Escape Kids, and several other Konami arcade titles (including the entire Konami GX line), has no schematics publicly available.

A die shot of this chip is available on siliconpr0n, but it still needs to be traced and its schematics still need to be derived.
