see xavix.cpp for basic notes
|

|

the machines using the '2000' series chips seem to have more extra

opcodes, so presumably these were only available in those models.
|
||||
of note, push x / push y and pull x / pull y
|
||||
|

Dirt Rebel MX, which is confirmed as 2000 type however seems to require
|
||||
some of the documented but 'undocumented' opcodes on the 6502 to have additonal
|

meaning for one specific function on startup

/* rad_madf has callf #$8f3f21 in various places, and expects to jump to code in ROM, it is unclear how things map in this case, as presumably

the CPU 0 page memory and stack are still at 0 but ROM must be in the 3xxx range (game hasn't got far enough to call this yet to help either)
|
||||
|

the maximum romsize appears to be 0x800000 so presumably the high bit being set has some additional meaning
|
||||
|
||||
for now treat it as a swapped arrangement vs. the reads from the lower range, except where page 0 ram would map, it's also possible that
|
||||
vram etc. is completely unavailable if executing from these addresses, there isn't much evidence at the moment
|
||||
|

note, many DMA operations and tile bank redirects etc. have the high bit set too, so that could be significant if it defines how it accesses

memory in those cases too
