2018-09-30 20:47:03 -04:00
Thomas Harte
2e4c4c3e91
Makes some attempt to implement paging.
...
This causes several of the 32kb games to be recognised by the BIOS and permitted to start, so it really really may be time to stop deferring work on the VDP.

SG1000 titles all seem to work now.
2018-09-23 21:55:07 -04:00
Thomas Harte
2253341904
This now goes far enough for the only SG1000 game I'm testing to start up.
...
Which hopefully gives me as much as I need to implement joypads, etc, and definitively get to just the VDP being outstanding.
2018-09-23 17:42:42 -04:00

e155dc8d6e

Thomas Harte
e7f4babf41
Starts taking steps towards SMS/GG and V9938/9958 support.
...
Specifically: routine namespace stuff, plus the intention to move to a table-based operation+cost version of timing. Reordering works fine for the TMS, and probably would also for the SMS/GG, but it'd be problematic with the command engine of the V9938/9958 and maintaining a consistent set of code is easier.
2018-09-17 22:59:16 -04:00
Thomas Harte
a8b116e217
Turns down the Apple II brightness a little.

Thomas Harte
0526ac2ee2
Slightly increases const correctness.
...
The converters from source data to output pixels do not modify the source data. It's a shame there's no `restrict` in C++.
2018-09-05 11:36:40 -04:00

About face! There should be no delay on serialisation, but a delay on interpretation-affecting soft switches.

Thomas Harte
be01203cc1
Starts to expand the range of supported 6502s.
...
This fully implements the NES 6502 because, well, it's virtually no extra work, and ensures that RDY takes effect on write cycles on 65C02s.
2018-08-13 22:17:22 -04:00
