1518ffbc60 Refactored ym7101 to store state unpacked
Previously it was storing data in the registers, which was an array
of u8, but now it's storing eg. full addresses for the scroll tables
so that they don't need to be fetched from the register values and
converted every rendering.  I was thinking this would maybe make
DMA debugging easier, in particular.

b540e53ea1 Fixed issues with Genesis controllers and sprite rendering
The controller th count was starting at 1 instead of 0 which caused
inputs to be read incorrectly, as well as the fact that inputs are
inverted.

The sprite fix now draws them in the right order so that ComradeOj's
sprite test renders correctly, but games still render them broken
because of some other bug yet to be found

cb47d23233 Fixed issue with colour 0 being the mask colour
For systems that legitimately use 0 for black, this causes a
problem, so I instead use 0xFFFFFFFF for the mask colour which
corresponds to transparent white in ARGB format, which minifb
doesn't support anyways

f601290771 Fixed bug in MOVEM and added tests for it
It was previously decrementing addresses if the direction was from
registers to memory, but that's incorrect.  It should increment the
address always when using an addressing mode other than the ARecDec
mode.  I also added a memory location to the test cases to test the
MOVEM instruction by comparing what memory was read/written (but it's
only one u32 because that's the minimum we need)

exiting the program.
