Text video RAM is situated at $D000-$D7FF.
|
||||
|
||||
The 68705 MCU handles the two coin inputs and drives the MSM5205 ADPCM chip.
|
||||
It also appears to serve as a simple protection device. During initialization,
|
||||
the main Z80 writes a special ADPCM code to the MCU and then spins in a loop.
|
||||
The MCU reponds by asserting the Z80's /NMI line, and thus the init process
|
||||
continues. The protection ADPCM code varies between versions of each game.

TODO:
|
||||
- MCU is identical between Empire City and Cross Shooter, it's ADPCM and
|
||||
perhaps coinage related too.
|
||||
- palette is incorporated - fix!!!
|
||||
- handle transparency in text layer properly (how?)
|
||||
- second bank of sf02 is this used? (probably NOT)
|
||||
|
||||
DONE? (check on real board)
|
||||
- sound (fm)
|
||||
- sound (adpcm)
|
||||
- stfight/empcity YM2203s should be clocked at 1.5MHz but this results in
|
||||
the sound and music being 1/3 of the pitch they should be. The game never
|
||||
writes the YM2203s' divider registers yet other games (e.g. Lock-On)
|
||||
suggest the default values are correct. What *is* going on here?
|
||||
- Each version of empcity/stfight has a different protection code stored in the
|
||||
MCU (at $1D2) so each 68705 will need to be dumped.
|
||||
We currently use hacked versions of the empcityu MCU for each different set.
