pjgat09 a56ddcdb15 Atari 2600: Modified how memory read/writes are handled, to better emulate the address bus. Cleaned up some comments. Turned off CPU debugging. Added functions to read console switches and player 2 buttons.

2012-03-21 01:02:24 +00:00
pjgat09 5e65c7e977 TIA: Removed code for cosmic ark starfield (to be added back later, in a cleaner way). Changed the definition of a frame to start with the first scanline where VSYNC is disabled.
MOS6507: Fixed a copy-paste mistake with SBC instructions where it would remove another cycle. This fixes the screen bounce issue with pitfall.

peter e310e90d9f Conditionally compile Windows code, make Throttle class portable, and add dummy input/audio implementations for non-Windows
This is (almost, bar some local resource hacks) enough to start the
emulator on Linux/Mono, load a ROM and watch the demo (input and
audio don't work yet).
