It's actually a limitation of their drivers, which can only take up to 32 custom timings. You can define more than 32 custom modes indeed, but not the required custom timings for them.

So since the ATI drivers needed hacking too, why did you pick those?

ATI drivers already support up to 60 custom video modes with their own custom timings without any hacking, compared to nVidia that has the 32 custom modes limit.
Anyway the most important advantage is that ATI allows dynamic modification of these custom timings on the fly, although this feature is undocumented afaik. That's how GroovyMAME can use recalculated modelines for each game.
Unfortunately nVdia drivers do not support this feature. I've done different tests these days using similar methods with registry modelines, but I'm afraid the new information is not used by the driver until the system is restarted.
However, semi-dynamic modelines will hopefully be possible for nVidia cards too in the near future, by using the Powerstrip API.

I recently acquired a MAME PC (configured with Soft15kHz, MALA and GuiMAME) with NVIDIA (AGP card) graphics but as I'm a very curious guy, I'd like to try GroovyMAME instead of the GuiMAME. ;D Also, it's 0.126 and I want to run the PGM games added recently.
So, if I just set it up to be run from MALA, will the correct settings for each game be used immediately, or what else do I need to do?

Yeah, GroovyMAME should use the modes set by Soft15Khz out of the box. However, as you're using a nVidia card, GroovyMAME won't be able to recalculate each modeline so it will run with the predefined ones. It won't be as good as running it with an ATI card but can't be worse than using regular MAME. And of course you can force the -syncrefresh -soundsync options to have perfect scrolling/sound in all games.

Thanks a lot for the reply. I tried this modeline:
mame gamename -nochangeres -hwstrech
and got fullscreen in a game (Ketsui, PGM hardware @ 224x448 59.170000Hz) that's normally not fullscreen (perfect modeline not available) but it is blurry. :hissy: :laugh2: If I use your modeline generator and create the resolution needed I should be able to add it by running Soft15kHz?
