- This may be related to the SubCPU. I don't think it's contributing - TOSHIBA TRJ-100 installed at the second board should contain the image
much right now, but I could be wrong. And it would explain that vast as U.S. Championship V'Ball has a TRJ-101 that contains it. A custom made
expanse of bankswitch ROM on a slave CPU.... adapter is needed to dump it.
- Just had a look at the sprites, and they seem like kosher sprites all
the way up.... So it must be hidden in the sub-cpu somewhere?

- TRJ-100 is accessed at about 3MHz speed, but seems to generate 5MHz clock
internally. This clock is exposed at the pin 22, and used as a clock at least
for some shifter ICs, such as IC110, 111, 112, and 113. Timers might be based
on this 5MHz clock, too?
