LazyCat's MAME rewrite?

[krick]

There's an interesting post in this MAMEWorld thread from a user named LazyCat.  I wonder if he/she might have information that would be useful for GroovyMAME...

By the way, I am making my own MAME re-write, just finished with frame-stepping algorithm, accompanied with numerous changes to how timing and general frame and audio syncing is handled there. Those changes fixed all the visual glitches and audio hiccups and crackling MAME is cursed with, as you know, or do you not?

Auto frame skipping algorithm is wrong. Some kind of attempt at telecine on the fly, but that doesn't work, it can not work. It's like dividing 5 by 3 and expecting to get a whole number as the result. There are only two properly working frameskip values in MAME: 6 and 9, (from 60fps -> 30fps, 15fps), but even using those would still leave you with audio syncing issues. You know what I'm talking about? Let me know if you wanna hear more.

It's Driverman. I take anything he posts with a gigantic grain of salt.

I went and read his posts there. He's STILL a pompous ass!

Sure, that's what I thought when I stumbled upon those posts during my daily google session. Removing MAME visual glitches and audio hiccups doesn't require any MAME-rewrite at all, anyway I'll be following that thread with great interest.

I read through that thread... some good intentions but he seems to have some adversarial undertones.
