* fix VRAM address calculation for GPU A
...
* add support for mode 5

keep the GPU from crashing if there's no VRAM mapped, I guess.
...
noting that the way it's accessing VRAM is grossly inaccurate.

* scheduler revamp, simpler design
...
* fix dumb bug of the year: ARM LDR opcodes would accidentally read twice, which fucked with things like the IPC FIFO.

move TCM shit to CP15.cpp. closer to the real thing (for example now DMA can't access TCM, etc).
...
the code is shit. I would use templates if only it fucking worked without requiring the function body to be included in a .h.
2017-01-30 19:11:29 +01:00
6f3b0498db
start refactoring shit: more accurate timing and way of counting cycles.

some beginning of sprite support: 16bit tiled sprites, not rotated or anything fancy
...
also give it a version number

* start GPU shit: draw BG0 16-color.
...
* fix a few DMA bugs.
* fix a bug where some code could still run right after a halt instruction.
* fix VRAM mapping, too. I'm an idiot.
