16731661e8
Switches back to being explicit about the colour burst phase.
...
Some sort of phase inversion otherwise seems to be achievable by software that switch modes often.

Thomas Harte
d4134cd0d8
Restores proper colour phase to the Apple II.
...
Given that its timing errors were fixed, this also switches back to using 'default' colour bursts — i.e. ones with implicit phase. The Apple II continues to be an excellent bellwether for issues in the pipeline, and this helps further to ensure that.

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.

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

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.
