Thomas Harte 02c786520a More fiddling in the margins in advance of doing the OpenGL stuff: window now supports full-screen display.		2015-07-23 20:53:26 -04:00
Machines	Looked up normal retrace time (it's a lot less than 16µs and 26 scanlines — more like 7 and 10) and that the visible portion of a line is defined to start about 12 µs after the start of hsync, put the first two numbers into my CRT to make that more accurate, then derived a newer guess about what the Atari 2600 does for each of its 228 cycles. The text version of a frame is now looking pretty good. So it's probably time to hit OpenGL and the OS X side of things. Though I'll have a quick look to find out whether I can learn the exact real Atari 2600 timings before moving on.	2015-07-23 19:24:25 -04:00

CLK

An attempt to unify my various bits of emulation; we'll see.
