APMSX supports 256KB games(Konami 8K ROM mapper)

I've upgraded the Konami 8K Mapper and now can run upto 256KB from 128KB.

It runs but, there is a issue .. Some sprites shaking and flashing.

When I decreased the speed to 2Mhz, it doesn't show same problem.

So, It must have problem on VDP control. maybe RAM accessing timing could be a issue.

I will check later when I need to debug the board.

ROM Mapper support would be finished with this Konami 8K mapper only.

256KB game running is good one. No MSX could run 256KB game without real ROM cartridge.

So, It would be OK for me.

Hope to like it too.

Thanks;
