You can use dgVoodoo 2 and force any resolution that you want. The game will be scaled to that resolution (for example, your desktop resolution). I'm not sure how well it works for 2D games like Jazz Jackrabbit, however, as I've used it only for 3D games.

Edit: I just tested and dgVoodoo 2 works very well with JJ2. It plays fullscreen (whereas, without it, JJ2 would run only in windowed mode) and scales nicely. BTW, you mention 1024x768, but there's not really any reason to scale to that resolution. Scale to your desktop resolution (i.e. the native mode of your monitor) by choosing "Max" as the resolution to force to in dgVoodoo's control panel.

Hi, DxWnd can scale, however it doesn't always work properly and can be difficult to set-up.

dgVoodoo 2 worked almost perfectly. Using WIP35, Jazz Jackrabbit can choose every resolution (except 400x300) and dgVoodoo scales it to fill my screen.

(Can I edit the video modes exposed by dgVoodoo 2? Is it possible?)

I mentioned 1024x768 (and 800x600) because:
- They are supported resolutions on my monitor (and most modern monitors).
- They are the double of 512x384 and 400x300 (both resolutions can be selected in JJ2), so using a simple 2x scaler I should get bigger pixels without any blur.

EDIT: Sorry, I've found that using ISF max resolutions the blurness should dissappear.

(BTW... is it possible to choose scalers/shaders on dgVoodoo 2 (i.e.: 2x, 2xSAI, scanlines...)?)

You can input any resolution (including refresh rate). Just type it in like the other resolutions. Mouse over the drop-down box's down arrow to read the tooltip.

I mentioned it because the monitor's native resolution is the only one that really matters on modern monitors. You're going to get blur with any other resolution, so you might as well just force the game to your desktop resolution or else you may add blur on top of blur (i.e. the wrapper is blurring the image by scaling it and then the monitor is blurring it because you're not at the native resolution). I would just put the game as high as it goes (640x480x16) and force it to Max (monitor native resolution) in dgVoodooCpl.exe. Edit: Yeah, Max ISF mode might be what you're after, since I believe that that'll matte the image against your desktop resolution... i.e. give you some black bars above and below, but keep the pixels sharp and unstretched.

The options for that are pretty limited. The "scaling mode" drop-down box on the General tab in dgVoodooCpl.exe has a few.

I guess that you mean the output resolution selector. I'd like that my game could "see" a 400x300 mode (and then scale to other resolution). I've been playing with the virtual card options (I've selected all video cards available) but none of them seems to support that.

Yes, but usually the monitor scaling is less blurry than the DirectX scaled filtered output.

I guess that dgVoodoo 2 is more oriented to 3D wrapping (where filtering can be OK and SAI scalers only make video output worse) than 2D, where using that kind of filters can be nice. I'd like to see a DLL that could apply filters to DirectDraw output...
