Buffer Size: 

                    This affects how often the registers are sampled, which can affect timing.

Acceptable lameness: (for now)

GPU: Rendering is per raster line. Mid-line changes won't appear like they coud on real hardware.
     No latching of values, so things like SSY scrolling can happen mid-frame, unlike real hardware
DMA: Occurs instantly, BUSY is always 0
PS/2 keyboard: Output to it is always ACKed and ignored
NES/SNES: Scan happens instantly
SPI: Only direct support for SD card commands that the microkernel uses
PRNG: Always gives random numbers, all else ignored
      Won't match real thing without 25MHz FPGA cycle exactness anyway
IEC: Not implemented in emulator
RTC: Watchdog timer ignored
VIA serial port: Not implemented in emulator
Buzzer: Not implemented
