I have an ArcadeVGA Radeon 7000 series and there's a known problem when running the Daphne laserdisk emulator on this card where hardware accelerated interlaced screens are stretched when displayed.
I run Dragons Lair with no acceleration to get the correct screen size but Space Ace is really jerky.
I found an article when reading about VGA-SCART leads where this problem is evident in all Catalyst drivers up to 3.4 when using a standard video renderer or overlay surface.
Is it possible to install Catalyst 3.4 with the ArcadeVGA? Would I loose all the custom resolutions or are they stored in the cards BIOS for the driver to detect? I'm just asking before trying because it's taken ages to setup my cab to get all the games running at the correct resolutions and I don't want to screw it up now!

Cheers.
