apparently when you set an out-of-bounds address for EEPROM, it should wrap around

TODO: check if it also happens with Flash
also fix shit that could have later turned into memory leaks

keep the GPU from crashing if there's no VRAM mapped, I guess.

noting that the way it's accessing VRAM is grossly inaccurate.

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.
