I finally got around to reading your PM (sorry for the tardiness, I've been swamped with projects). I have a 27" Betson and an arcade VGA2 - very similar setup. Well, I used to... I've since upgraded my video card to a stronger ATI card running "Soft 15KHz" instead. Same monitor though.
I run the MAME res tool and it seems to run fine on my system. I've run MAME res on WinXP Pro SP3 and also and Nlited version as well. They both work. Not sure why yours gets that error. Have you tried contacting the author? He's very helpful and a member here at BYOAC.
Glad to hear that you got the problems resolved. I wouldn't mind taking a peek at your .ini files. Any chance you can attach them somewhere?
Also, did you get your vertical games to work? How do they look? Ms. Pacman? Donkey Kong? Punch Out?

Hey dude and sorry for the late reply.
I have no idea why MAMERes Tool didn't work, but as I got AVRes working fine I didn't spend more time on it. There are still some vertical games that doesn't look right though (mostly because top/bottom is cut), but my favorite classic vertical games like Donkey Kong and Bomb Jack looks great, so I haven't spent time trying to find alternative resolutions. Ms. Pac-Man is cut as far as I can remember, so I will have to try to fix that one, as it's one of my favorites.

The only small issue I have left now is the fact that when I adjust one game, another one might get off-center/stretched etc. I think I've went through (and adjusted) all possible resolutions now at least 5 times, but there are still a few games that gets off centered etc. Do you have the same issue?
Do you want all my game .inis or just my mame.ini etc.?
