Age	Commit message (Collapse)	Author
2013-10-01	Implement turbo/slow motion feature that overclocks or underclocks the ↵	Mike Pavone
	entire system at the push of a button
2013-09-18	Theoretically more correct timing of Z80 bus request	Mike Pavone

2013-09-17	Implement HV counter latch	Mike Pavone

2013-09-17	Implement funny behavior for DMA fill to CRAM and VSRAM. Return VSRAM ↵	Mike Pavone
	address 0 for reads to VSRAM at >= 40
2013-09-17	Fix DMA fill so that it does not cause observable changes to the FIFO. Get ↵	Mike Pavone
	DMA copy mostly correct from an observable ffect perspective. DMA copy probably does not reflect internal implementation still given that evidence seems to suggest no FIFO usage at all.
