211. native stack pointer
222. current cycle count
233. target cycle count
244. cartridge address
255. work ram address
266. scratch register
277. context pointer (contains 68K registers and memory pointers not in registers)
288. status register (maybe, depends on how well I can abuse native x86 status stuff)
