Altirra 2.4 test 14.
Looked at the colors issue, but don´t know what it could be -- Altirra definitely does use PF2 in artifacting calculations, even in standard mode.
Fix for XEP80 view settings not saving properly, adds .WAV recording, and supports per-monitor DPI on Windows 8.1 preview.
The .WAV recorder uses a more aggressive audio filter with a sharper cutoff than the regular playback path, so I´d be interested in thoughts on whether it is more or less authentic.
