| mcr68: mapped 6840 to lower data bits on all mcr68 games, which matches the blasted schematics. I used cswidth as different games write at odd or even addresses, even though the boards look visually similar. Byte writes will work in either case as the 68000 puts the same data on the upper and lower part of the bus. Reads are a mix of odd and even addresses, International team laser and spy hunter 2 exclusively read at even addresses. It's unclear whether this is a bug in those games or not. [smf] |
