A small couple of hours update to this prog ended up being pretty much a complete re-write:
M.A.M.E. Resolution Tool v2.0 (18/02/05)
Changes:
Removed 'ArcadeVGA' from the title of the program to avoid discouraging non-AVGA users from using it!,
MAME's orientation info now used (rather than just assuming if x>y then game is horizontal),
Improved resolution selection, particularly for games with different orientation to screen,
Settings window improved so actual ini-style editing can be done,
Added feature to allow refresh rate matching as well as resolution,
Test function improved so that exact config is used (WYSIWYG),
Added automatic reading of existing ini files,
Added ability to only generate ini files for romsets you have available (zipped roms, single rom folder only),
Added ability to only generate ini files for parent romsets,
Added ability to only generate ini files for romsets which don't already have an existing ini file,
Made numerous small changes,
Cleaned up and improved code technically throughout.
For people who don't really need this app. it has a feature which may be a nice side effect. You can edit existing ini files, make any changes you like, and save the ini's once again. You can apply settings to all games, all games with the same (native) video mode, all games with the same orientation or one game at a time. Also, you can create ini's for parents only, available games only, games without an existing ini etc....maybe some use to somebody, I don't know

Please email me any bug reports, although I can't guarantee to fix them for a few months...see here for why:
