dendego - 電車でGO! (Ver 2.3 J)
 
概 要速度が遅すぎて音声とシンクロしない。
詳 細When running dedego, the graphics rapidly descync from the audio by running too slow.
I've attached a video showing the problem.
This occurred somewhere between 0.266 (Working, correct speed), and 0.267 (too slow), I believe the culprit may be

-cpu/m68000: Updated 680x0 FPU to Softfloat 3 from 2.
or
-cpu/m68000: FPU now sets the NaN flag for all NaNs, not just signalling. Fixes dendego black screen in attract mode.

I've turned on the speed counter in both videos, so you can see the regression is not related to an overhead in performance (both run at 100%) , but probably some miscalculation somewhere.

Watch intro - note the audio/video desync.
追加情報Ignore the incorrect colours in the video, these are not present outside the capture.
