Age	Commit message (Collapse)	Author
2013-10-27	Basic OpenGL rendering is working	Mike Pavone
	--HG-- branch : opengl
2013-09-17	Set VBLANK flag in status register when display is disabled	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.

	and VSRAM bits can be implemented properly
2013-09-13	Properly delay 68K on VDP reads. Dummy VDP test port implementation. Initial ↵	Mike Pavone

2013-09-01	Fix bug that caused a DMA fill to start after another DMA operation ↵	Mike Pavone

2013-06-23	Fix window layer in double res interlace mode	Mike Pavone
