strangely features the same encryption as used on the DE-0219 board. It
|
||||
also has some edited graphics.
|
||||
|
||||
The DE-0219 PCB seems to have only one 12 MHz XTAL, some images with recognizable XTAL value can be found here:

- Lots of unmapped memory reads and writes (sprram or vram mirrors, perhaps...), bg_vram is also read.

- Does the korean bootleg really have the DECO 222 CPU? I think it should use the shootclr.003 prom to decrypt the opcodes.

Something like -> rom [addr] = (rom [addr] & 0x0F) | proms [rom [addr] >> 4]]);

This is actually a double BCD counter (2 BCD digits packet in a byte)...

The first write is always 0x40, then when a coin is inserted it starts to count from 0x01 up to 0x99.
|

When it reaches 99 credits, 0x99 is always written...
|

On the shootoutj and shootoutb sets, it works as above but it counts up to 0x09 instead of 0x99 (Single BCD digit).

Note:
|

This should be an input for a BCD to 7-segment decoder (e.g. a 74LS47), but all the PCBs I've seen don't have 'onboard'

display(s), so this was implemented as normal "coin counter" (after all, they both have the same goal: count credits ;))
