Title: Problem with Narc and picture size?
Post by: emuola on July 04, 2011, 11:48:47 am

Running Advmame/advmenu (Linux) and almost everything is fine :) Using Matrox G400 hooked up to a 21" Hitachi "standard" vga monitor to get pixel perfect resolutions. I have problems with Narc (reported resolution is 512x400), because the picture seems to be somehow cropped from the sides (see attached unfortunately crappy image).
As you can see, the whole image does fit on the screen and it's even nicely centered so there's nothing I can do with the monitor controls. Somehow advancemame thinks that the whole picture is shown although it's clearly not. Other games/resolutions run ok :)

Am I really stupid or something here?

Ok, I also tested Cruisin' USA (also has 512 x 400) and the problem is the same. So for some reason the picture is too big with games having the 512 x 400 resolution. Any clues for this?

*edit*
Checked the xorg.conf and found this modeline:

Code: [Select]

# 512x400x57.00 @ 49.932kHz
Modeline "512x400x57.00"  31.956480  512 528 608 640  400 404 406 438  -HSync -VSync doublescan
I guess some of those numbers are wrong. Would anyone here have a clue how to fix this?

Ok, solved... Had to choose "mixed" as the scaling method (previously "none") for games using this resolution (512x400). Not pixel perfect anymore, but it works...
