2020-02-16 18:31:45 -05:00
Thomas Harte
9835e800ec
Fixed: individual audio generators now either are or are not stereo. The speaker acts accordingly.

Thomas Harte
6bda4034c6
Ensures no input data is dropped when changing output rates.
...
I think this 'completely' deals with the problem. At least until someone wants dynamic output buffer sizes or something like that. We'll see.

All these 'override's can be 'final's.
...
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

Adds the necessary routine for all machines to be able to respond to get_scan_status.
...
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.

Resolves a potential out-of-bounds array access.
...
Risk was: allocation exactly joins end of buffer. In which case the next get_data won't wrap the texture y coordinate since it won't spot an x overage.
