Hello everyone,

I have a minor problem with the svga_paradise mode when using Windows 3.0 with Multimedia Extension 1.0 (Tandy) and
the Western Digital 640x480 256c drivers on Windows 3.1.
The driver both work, but the image is corrupted in both Standard-Mode/386 Enhanced-Mode.

What confuses me a bit:
- The WD/Paradise driver from Windows 3.0 MME does not work (286/386 mode)
- The WD driver does not work in 640x480 256c
- The WD driver works in 800x600 16c (286/386 mode)
- The WD driver works in 800x600 256c (286/386 mode)
- The WD driver in 1024x768 16c works partially (286/386 mode)
- The old Windows 3.0 Paradise 640x400 256c driver works (286/386 mode)
- The old Windows 3.0 Paradise 640x480 256c driver (286/386 mode)

So could it be that the Paradise emulation (PVGA1A, PVGA1B?) is somehow incomplete? Or is the VGA memory limited to 256KB?
Or maybe, that the Western Digital driver is using features of the WD90C00 that's not present in the older Paradise Professional VGA chips or their VGA BIOS?

Please forgive my ignorance, if this is already fixed or if this has other causes.
I expected the 16c driver to work, due to its non-paletted nature, but this..

I'm using the DOSBox that's available via Raspbian's packet manager.

Best wishes,
