Yeah, this is normal behaviour because the TSR preserves the aspect ratio of the original resolution. Afaik, it can only scale neatly between resolutions that are multiples of each other, and since 1024p is not a multiple of 320p, you get the borders to make up the rest of the screen space. Ah, on …

I know FastTracker II uses a 640x400 mode... Perhaps it tries to maintain square pixels or FTII uses some video signal trickery for its timing. Can you try Wolfenstein 3D? It has become my test game of choice to test videoscaling on my videocard.

Can you post a pic? And your 800x600 application is full screen after using the TSR?

The BIOS screens will remain cropped as the TSR is loaded after that. Try VEXP M2 to see if that gives you full screen in DOS. Scaling graphics/text mode are seperate functions of the video card.

If it uses the CT65554 chip you'll need this: http://web.archive.org/web/19990219171930/htt … com:80/vexp.htm

Super Street Fighter 2 Turbo and MegaMan X are able to map 6 fire buttons, these games sometimes came with a 6-button controller. For info see: https://www.vogons.org/viewtopic.php?t=33322 I think you can connect only 1 extra regular gamepad in normal mode. More than one requires GRiP (it has a …

Had a Gravis Gamepad (dogbone) for years, never had the diagonals issues with it. I thought that was a problem with the Gravis Gamepad Pro (the PSX controller lookalike). I've tried some 15-pin gamepads over the years but most of them are kind of disappointing when you're used to console pads: - The …

Can you try Heretic and see if that runs better than Doom? They both use the Doom engine but Heretic uses Mode 13H. Some systems/cards have a hard time with Doom's Mode-X graphics.

I think the drive belt went bad. Should be replaceable. Edit: Nevermind, could have sworn I saw a belt in my transparent Iomega ZIP 100 USB, apparently not the case.

You need to give more info; I guess this is a VGA card connected to an LCD screen? Could be the DACs on the card, could be the LCD not liking DOS resolutions. What cards did you test? Trident? Cirrus Logic? Tseng? They are known to give LCD's a hard time with vertical bars.
