f68565a33f Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine. 2017-08-17 10:48:29 -04:00

de1c526789 Cut the amount disclosed by the Atari 2600 for public inspection down to the minimum, relocating implementation into the .cpp. 2017-08-16 14:52:40 -04:00

06e31f5102 Consequential to the 6502 change, severs the Atari 2600's cartridge container from its former attempt at runtime polymorphism, in favour of each cartridge's specific hardware being defined as a 'bus extender'. 2017-08-16 12:39:15 -04:00
Thomas Harte
42b5b66305 Remove the 6502's use of runtime polymorphism in favour of ordinary templating. 2017-08-16 11:56:52 -04:00

Thomas Harte
33bda2d40c Switched to image inspection for RAM guesses rather than disassembly. Which fixes the other Parker Bros titles. 2017-03-11 13:04:23 -05:00
Thomas Harte

Thomas Harte
9c72ce5bd2 Ensured a settling delay is permitted before an NTSC/PAL decision is made. To avoid false switches just due to startup. 2017-03-06 19:37:35 -05:00
Thomas Harte
d3257c345a Tested against public ROMs and corrected. Also moved the deferred adjustment into a more canonical place. 2017-03-04 17:00:28 -05:00

98376de9ad Started returning 'no effect' for pot ports, rather than doing nothing. Still very much TODO though. 2017-02-25 22:58:58 -05:00

Thomas Harte
99a35266e1 Attempted to bring frequency-switching logic into the cross-platform realm. Which for now creates an issue with the OpenGL context. 2017-02-19 21:20:37 -05:00
Thomas Harte
600bdc9af7 In C++, I think the implicit cast to bool negates the need for any manual collapsing? 2017-02-12 18:18:35 -05:00
Thomas Harte
a477499724 Got a bit more explicit with range returned by get_cycles_until_horizontal_blank and hence attempted a more thorough (/correct) version of WSYNC. 2017-02-07 22:14:45 -05:00
Thomas Harte
92754ace7a Some mild fixes get me up to having a rolling screen of vertical lines. Which is what I was hoping for right now! 2017-01-29 22:16:23 -05:00
Thomas Harte

Thomas Harte
a246530953 Supposing the TIA were implemented, this is (more or less) what the Atari 2600 would now look like. 2017-01-28 21:46:40 -05:00
