03c1a9cbc8 more anti-crash.
don't unmap VRAM in cases of overlaps. fixes NSMB minigames, for now.

594286ee5d * 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.

d7c1d2a2cd * 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.
