I could not attach it properly as 'General > 16 cartridge'. The memory mapping of the MV is quite complicated. I think it starts up in Ultimax configuration (ROM at $a000-$bfff and $e000-$ffff), and then copies part of the code to $c000-$cfff. Then the memory configuration is changed, so the C64 Kernal and BASIC is active, and a normal 8k cartridge ROM at $a000-$bfff is present (or does it also copy to RAM $a000-$bfff? I forgot.). So it behaves quite differently than a general 16k cartridge ;) Nicolas -- -> My Commodore hardware projects and the X1541 Shop at http://x1541.de <- Message was sent through the cbm-hackers mailing list
