Whoops. So the memory map in ultimax mode for the CPU is extremely boring: 0000..0fff: ram 1000..7fff: - 8000..9fff: cartridge low a000..cfff: - d000..dfff, (read and ba) or write: i/o d000..dfff, read and not ba: ram e000..ffff: cartridge high and for the VIC is completely crazy: 0000..0fff: ram 1000..2fff: - 3000..3fff: cartridge high 4000..6fff: - 7000..7fff: cartridge high 8000..9fff: ram a000..afff: - b000..bfff: cartridge high c000..cfff: - d000..efff: ram f000..ffff: cartridge high :-) Segher Message was sent through the cbm-hackers mailing listReceived on 2012-05-10 19:00:43
