I´m not sure that I have the latest Stella, but it the one I have doesn´t
emulate the 6507 data bus correctly. This is not that hard to do from
scratch, but might be a different thing now, since the whole emulator has
been
written.
Also, doesn´t seem that addressing any RESXX register within 24 cpu cycles
after an HMOVE, leaves the object in the right position. BTW, how PCAE or
Z26 handle this?
I´ve solved this in my emu with some kludges, like if the RESXX occurs 21
cycles after HMOVE I add 2 to the object expected position, or if it occurs
at 20, I add 5, etc... Most likely, which RESXX is addressed should be taken
in consideration, an
maybe even at which colourclock HMOVE is addressed too, but this way seems
to be working fine for most games...
Bye,
Nicolás.
