karnov.c

0.31 [Bryan McPhail]


NOTES:

- Karnov USA & Karnov Japan and Chelnov USA & Chelnov Japan have different gameplay (!). These games use a 68000 main processor with a 6502, YM2203C and YM3526 for sound.

- Karnov was a major pain to get going because of the 'protection' on the main player sprite, probably connected to the Intel microcontroller on the board. The game is very sensitive to the wrong values at the input ports.

- One of the two color PROMs for chelnov and chelnoj is different. One is most likely a bad read, but I don't know which one.

- Karnov dipswitch: 0x80 called No Die Mode according to the manual, but it doesn't seem to have any effect


VIDEO HARDWARE NOTES:

- Karnov has two 1024x8 palette PROM. I don't know the exact values of the resistors between the RAM and the RGB output. I assumed these values (the same as Commando).
