- DE156 clock: 7.000MHz (42MHz / 6, QFP100, clock measured on pin 90)
Stadium Hero contains a '146' protection chip on the ROM/CPU pcb, but
it is barely used by the game (only checked at startup). See decoprot.c
it is barely used by the game (only checked at startup). See deco146.cpp.
Driver TODO:
stadhr96 - protection? issues (or 156 co-processor? or timing?)
avengrgs - doesn't generate enough line interrupts?
ddream95 seems to have a dual screen mode(??)
hoops** - crash entering test mode (regression from 0.113 era?)
skullfng - slowdowns not verified from real PCB, Random hangs sometimes
