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 ;)
