My newest problem... well one remaining problem really, other than this GroovyMame is brilliant and running on Arch Linux it has become my perfect lag free, smooth scrolling set up. :)
...is some games, eg. Kung Fu Master, R-Type and Indiana Jones and the Temple of Doom (to name a few) seem to be getting upscaled by the video driver and rendering with a lot of anti-aliasing rather than the solid blocky (integer?) scaling I prefer. :(
At first I thought it was all horizontal games, but a few like Neo-Geo games are fine.
I'm using an LCD 1600x1200 monitor, and have the monitor set to lcd in the config. Whether it's blocky or blurry, game info always says SwitchRes is using the native resolution.
Any advice on preventing this from happening?
TIA

It could be a ton of things, posting your ini files in the thread might help you get better advice.

Attached!
It's basically the default -createconfig with the following values changed:
autosave 1
joystick 0
skip_gameinfo 1
disable_nagscreen_patch 0
disable_loading_patch 0
monitor lcd
video opengl
audio_latency 1.0

Any ideas anyone? :(

Is opengl the only setting you can have for video? Just as a total guess.

You might disable hwstretch though as I remember it was designed only for ddraw.
unevenstretch never worked for me. Long time ago there was disscussion at mameworld. This option does not do anything, it was simple never finished.

Hi RobertJ,
Rather than your mame.ini, it's a log taken from GroovyMAME what I need. Bear in mind GroovyMAME modifies some of the options as required, depending on each game, so without a log we can't be sure of what options are actually being applied. My guess is that unevenstretch is in use by the games affected, simply because GroovyMAME can't find a good integer scale factor for those (one that doesn't produce huge borders). Try launching one of these games with the -nounevenstretch option from command line. If that fixes the problem, create a custom .ini file for that game, *only* including this option.

Also read about the -cleanstretch parameter... if resizing is involved it might help.

Thanks for the replies! I'll try a few things.
Interestingly, the problem may have vanished when I was adding the uncleanstretch param, not because of that (it made Kung Fu Master tiny on the screen) but because I realised in the Attract front end I'd had -prescale 1 set. So removing that may have done it.
Fingers crossed.
