irem/olibochu.cpp: Tweaked refresh rate (~62hz), misc. cleanups (no functional change) (#12703)
* irem/olibochu.cpp: Tweaked refresh rate to ~62.5hz. - Moved sound interrupts to scanline timer. - Documented flip screen latch(?) usage. Seems to be debug or diagnostics? - Added PCB references to the driver notes. - Convert graphics definitons to macros. - Reduced tag literal usage, more const specifiers. - Reduced duplicate sprite drawing code. - Converted palette to compute_resistor_weights (resistances are a guess).

NOTES:
|
||||
- Irem M47 hardware? (according to PCB, this is all we have)
|
||||
- Doesn't seem related to later Irem designs (M52, etc.)
|
||||
- PCB (Punching Kid): https://youtu.be/ImUpedYnfME
|
||||
- PCB (Oli Boo Chu): https://youtu.be/nPzBmCDtHO0
|
||||
- Punching Kid has a POST with zeroes across the screen, Oli Boo Chu shows nothing.
|
||||
Punching Kid also doesn't play a sound when Boo drops food. The "CHU HAS FOOD"
|
||||
sample isn't played in either version (no write to sound_command...)
|
||||
|
||||
TODO:
|
||||
- accurate video timing, irq timing
|
||||
- HC55516 should actually be HC55536
|
||||
- verify HC55536 clock, I don't think it's from master XTAL, maybe R/C osc
|
||||
- is the "Chu has food" sample ever played? Nothing is written to soundcmd when
|
||||
a Chu eats a Boo dropping
|
||||
- verify video timing, PCB video reference does imply a 62.5Hz refresh rate
|
||||
- accurate IRQ timing
|
||||
- does it have Z80 waitstates?
|
||||
- HC55516 should actually be an HC55536, the "OLI IS OUT", sound is also muffled
|
||||
compared to known PCB footage.
|
||||
- verify HC55536 clock, I don't think it's from master XTAL, maybe R/C osc.
|
||||
- Diagnostics outputs? See flip_screen_w for an explanation.
|
||||
- Verify the PROM color resistances, seems to be standard.
