Summary MESS-specific 06455: dendy: timing regression causing major slowdown in all software
Description Slightly hard to explain, but all games on set "dendy" play at half the rate of speed they should play. This happens in both the latest git commit and the 0.180 release.

I have not found any issue that might be the clock; Rather, I think it might be the refresh rate or the vblank time causing issues.
Steps To Reproduce 1. launch any game from softlist
