At 0x16cde, a move writes an invalid value to 0 via an indirect %a2 reg. The value of the reg might have changed during an interrupt, but it definitely breaks when the next interrupt occurs
Before the loop is 0x16a0e which then calculates the count and such
0x16584 is where the memory address 0xffd11a is updated, which is then used for the bad 0x0000 address which causes the improper write. 0x16570 is a better start
On broken cycle: %a1 = 1df40, moves that location + 1 to %d0
* could have a remapper device, which takes a big swath of addresses in and maps them to another set of addresses (for Mac VIA generic to bus-hookup-in-mac adapter)
* i need a better way of handling disperate reads/writes to I/O spaces, rather than having multiple devices or having a massive chunk of address space allocated, continuously
* should you modify Addressable to also take the absolute address as input? I'm thinking of how the same device could be mapped to multiple addresses in memory instead
* could you use a generic sharable signal thing for sharing data, such as the VIA in mac128 where a single output bit determines the video mode (which would be a separate device)
So both could share the same Signal, one setting it and the other reading it, but how would you actually configure/build that?
* YM7101 timing is causing it to be very slow... speeding this up increasing rendering speed a lot, even though the frame shouldn't be drawn that often... not sure what's wrong with the timing
* make the ym7101 set/reset the v_int occurred flag based on the interrupt controller
