Soft-15KHz - slim new tool for 15KHz on normal vga cards

The ultimarc/soft15 modes seem to be good approximations to meet 95% (or more, I don't know as I'm not a pokerom) of cases. It depends how picky you are. I think the really picky advancemame users create a special timing for each game. Incidentally, it seems Advancemame and regular MAME treat the same modes/timings differently.

Ok thanks.
I'm not that picky , so will proably just go with the standard - although I think getting correct refresh rates is most important as it stops all the nasty juddering/tearing on scrolling...
SailorSat:
just enable tripple buffering and disable "throttling" and you will never have any tearing again ;)
to bad mame doesn't export the "real" modeline of the hardware it emulates (okay neogeo mentions the modeline in the source)

Really? I appear to still have difficulty. Triple buffering helps but seems to cause odd slowdowns when used with directdraw on my system.
If I enable vsync I get rid of tearing but get that nasty 'jump' every few frames....
What does throttle do exactly - throttle game speed to current vertical refresh?

I get an 'erk' every few seconds using triplebuffer on some games. Mainly namco vertical games - pac, mspac, and mappy. As for throttle, uncheck it and the game runs at the horizontal refresh. FAST. Maybe it's different in cabmame?
SailorSat:
throttle keepts the game run at "100%" original speed.
if you disable it, the game runs as fast as it can.
tripplebuffer limits the game to the vertical refresh rate (i.e. 60hz)
however there still is the "frameskip" which should be set to 0 to avoid those "bumps".
the downside is that the sound gets disorted a little (some games more, some games less) until your useing either cabmame or mameuifx (or any other mame version with a soundsync "hack")
there's allways a small tradeoff in "perfect" emulation until you get the perfect modeline.
