Thomas Harte	e93dbdb463	Implemented keyboard input.	2016-01-11 19:48:31 -05:00
Thomas Harte	0db8938d27	Added the option for the CSCathodeRayView to show only a subsection of the full scan area. Zoomed in a little on the 2600. Put in enough piping to give the Electron sight of its ROMs at least.	2016-01-06 23:14:36 -05:00
Thomas Harte	616dc0b57c	Okay, so this is the absolute bare minimum about of refactoring and wiring necessary to get the [unimplemented] Electron machine pumping.	2016-01-04 23:40:43 -05:00
Thomas Harte	43ab8bbad5	Okay, so then here's a first shot at the Objective-C -> C++ bridge for the Electron.	2016-01-04 23:16:37 -05:00
Thomas Harte	ab45c1d530	Started working on a shell for the Electron emulation, including factoring out the common CRT delegate -> Objective-C bridging, serial dispatch queue and frameskipping logic from the Atari 2600 shell.	2016-01-04 23:12:47 -05:00
Thomas Harte	aa0714fe27	Started sketching out an Acorn Electron emulation, as it's a platform I'm familiar with and will force me to figure out PAL decoding. Factored out NTSC-specific parts of the display decoding logic and hence added RGB output mode.	2016-01-03 20:41:43 -05:00
Thomas Harte	bc805a90fe	Wired up joystick directions, at least, and fire button presses get as far as the C++. But there's some latching to figure out before they'll work.	2015-08-18 20:33:24 -04:00
Thomas Harte	a693c081f8	Switched on the appropriate compiler warnings re: signed comparisons and implicit conversions. Fixed all less-than-explicit calls.	2015-08-16 16:08:29 -04:00
Thomas Harte	d19f8ed507	Removed the implicit reset upon 6502 startup, adding a reset line. Hence all tests now pass again. Added an empty shell for timing tests, the all-RAM 6502 now counting bus cycles.	2015-08-13 00:51:06 +01:00
Thomas Harte	3c25ead1f3	Started working out some of my retain cycles and general failures to release. Switched .mm filename so that Xcode will stop getting confused when I try to switch between implementation and interface files.	2015-07-27 21:15:10 -04:00
Thomas Harte	6252f6030f	Switched to idiomatic source name, ensured latest project name is in all appropriate header places, threw texture coordinates slightly into the shader mix.	2015-07-26 15:25:11 -04:00
Thomas Harte	ecb2898bd5	The overall architecture of who has responsibility for what is now very askew but: the CRT now outputs a tightly packed short buffer, with the probable OpenGL destination in mind. So it's now all fixed arithmetic internally. CRTFrame is reduced to a plain C struct with the intention that the OpenGL view will take responsibility for it and stop doing the back-and-forth sprint on getting buffer data. The Atari 2600 now outputs explicit blanks rather than level blacks for its border, so that it's easier visually to debug the CRT in its form as far as it has currently progressed: to drawing lines where the cathode ray gun would run while outputting pixel. I note that I'm still not quite getting vertical sync right yet — I'm just accepting it anywhere in teh frame — but that should be an easy fix.	2015-07-24 23:29:45 -04:00
Thomas Harte	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
Thomas Harte	e0aa1e9f19	Minor project rearrangement to aid findability.	2015-07-17 09:10:23 -04:00
Thomas Harte	1df2c48668	Introduced my GL view as the window content.	2015-07-16 21:01:49 -04:00
Thomas Harte	5160b6bbb8	Separated out different test suites into different XCTest subclasses.	2015-07-16 20:52:16 -04:00
Thomas Harte	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
Thomas Harte	24c0579b94	Shuffled things and guessed at things until the Xcode project was happy being subservient to the project proper.	2015-07-16 20:27:31 -04:00
