Fixed aforementioned issues.
[From a previous post:
- mul was using r(d) instead of r(n) for accumulate.
- mull didn't remove c/v clear.
- APU register mask was broken, so SOUNDBIAS was reading out wrong.
- APU was only mapping 0x088 and not 0x089 as well.
- Halfword reads in CPU+PPU+APU were all reading from the low address
each time.]
All CPU+PPU registers are now hooked up (not that they do anything.)
SOUNDBIAS for APU was hooked up, got tired of working on it for the rest :P
I recall from the GB APU that you can't just assign values for the APU
MMIO regs. They do odd reload things as well.
Also, was using MMIO read code like this:
return (
(flaga << 0)
|| (flagb << 1)
|| (flagc << 2)
);
Logical or doesn't work so well with building flags :P
Bad habit from how I split multiple conditionals across several lines.
So ... r14 is basically what r13 should have been yesterday, delaying my
schedule by yet another day :(
