74dfe56d2b
Expands documentation of NMI setting. 
Given that it was previously incorrect, explains logic behind request_status_ and last_request_status_ setting. Also takes the opportunity to ensure that NMI is 'sampled' at the same time as IRQ; whether the next thing should be the NMI routine now occurs one cycle before the end of any instruction. That's an assumption for now. Testing to come.

b02e4fbbf6 Corrects NMI receipt to be genuinely edge triggered. 
Previously a caller that signalled NMI set multiple times would trigger multiple NMIs.

86239469e7 Allows SN76489 consumers to apply an additional divider that reduces computation. 2018-03-01 18:51:05 -05:00

87760297fc Fixes underpumping of SN76489. 
Audio works now. Though I still need properly to confirm who owns dividers in practice. I think probably all division should be within the SN.

204d5cc964 Extends JoystickMachine protocol to cover ColecoVision use case. 
Also thereby implements input on the ColecoVision, in theory at least. No input is being fed though, so...

d83178f29d Makes an attempt at implementing all missing TZX 1.20 blocks. 
Towards that aim, simplifies CSW handling so that even regular RLE compression uses a static grab of file contents.

ddf1bf3cbf Reintroduces options selection for the Mac. 
For everything except the Vic-20, anyway. That has a somewhat outdated notion of what an options panel should be, corresponding to the work yet to do on its analyser.
