Games with ISSUES: report here!
Calamity:
Hi mazinger, try running it with -triplebuffer (to discard CPU power).
mazinger-z:
With triplebuffer enabled, the game stutters much less (once in a while) and is playable. Speed is 97.20%.
With triplebuffer enabled and sound disabled, it works more or less the same (maybe a tad better). Speed: 99.10%.
With triplebuffer disabled and sound disabled, it stutters and slows down like before. Speed: 84.00%.
Calamity:
The results with triplebuffer match the ones you're getting with official MAME, which means the issue is CPU related, I'm afraid. As a general rule, you shouldn't use syncrefresh for a game that can't reach a 100% speed when run without it (triplebuffer).
The fact that you're not getting a 100% speed with official MAME means that your CPU needs more than 1000/Vfreq ms (1000/54.81570 = 18.24 ms for mk2) in order to render some of the game's frames. In these circumstances, enabling syncrefresh will reduce performance dramatically, as much as 50% in some cases, because many of the vertical retraces will be missed and the CPU will need to wait for the next one.

Anyone noticed how many times switchres is called in "diehard" ? For the start it gets called >10 times!! It makes my arcade monitor go nuts with flickers.
And in all cases, it switches to same resolution! Is this a bug in Diehard? Tried in 0.145 ..

I've tried diehard and it switches resolutions a lot indeed, I'm not sure if the original game behaved like that or it's some kind of error in the routine which detects resolution switching. Actually the change is nearly not perceptible in my monitor but some other monitors shake a lot for mode switching so it can be nice to disable the -changeres option for that game.
