a1a1b15d18 Made a quick attempt to accumulate a list of detected output runs. Which means finally having to specify normal frame height. I'm already at too many magic formulae though, so this will need proper revision when I'm next awake. Definitely my horizontal position advancement is way off. 2015-07-20 23:18:56 -04:00

4e4c082a05 Made some minor attempt at proper sync response. I think I've gone way off piste and overcomplicated it. 2015-07-19 23:43:22 -04:00

4a1e9fe2a8 Rephrased the CRT as owning an arbitrary number of buffers and vending storage space for pixel output. That much better maps to potential implementations of this thing in GLSL, with ES 2.0's limitations kept in mind. 2015-07-19 21:21:34 -04:00

4d1e410150 Fix 1: _horizontalTimer should be treated as read only out here. 2015-07-19 16:51:11 -04:00

6f78ecdc9c Made first genuine attempt at outputting a meaningful CRT stream. Which shows some significant errors. So work to do. 2015-07-19 16:48:14 -04:00

2d0f861474 Incoming: a 'CRT' class, to receive information intended for a cathode ray tube. To decode sync, etc. 2015-07-19 13:36:27 -04:00

03a25c8ff2 Fixed playfield pixel logic. 2015-07-19 10:56:04 -04:00

3e0679235a This now goes just far enough to create an instance of Atari2600::Machine and push a ROM to it. Next jobs are to get a basic CRT emulation wired up, outputting to the window. 2015-07-16 20:40:46 -04:00

6558ae1425 Imported what little I have so far in the way of a memory-access cycle complete 6502 and just enough of a pretend Atari 2600 on top to be able to see some playfields in ASCII art. 2015-07-16 19:56:02 -04:00
