Edit: Ah! It's an Win64 application ?! If so, then never mind, it wouldn't run there anyway. No, it's a 32bit one. :) inpoutx64.dll was not working, so I had to do do it as a 32bit application. :) My original plan was to size it for 1024 * 768, but I run out of space on the window. :D Hi there! …

Personally, this worries me a bit. The statement is a bit hollow, I think. The specs of the test system are not just vague, but unknown, even. . I think that one of the main pros of (2D/GDI) hardware acceleration would be in emulation, where e.g. the native Windows rendering code would be run under …

Hi there! I think I've got the same card in the attic somewhere! It's a nice antique, cool for testing purposes. If you change the Olivetti VGA BIOS to a generic PVGA1A BIOS, it should work. Tips: - The Paradise Professional VGA (PVGA1A) is similar to the later WD90C00. Other revisions exist (1B, 1C …

Yeah, because malware authors are very concerned about security and support recent operating systems only. I'm sure they also follow Microsoft's recommendation and stop supporting older systems once they go EOL. Of course, they do use the most current Visual Studio releases for best user experience …

Ah, that's cool! Reminds me of my parallel port experiments with Win 3.x/9x and Visual Basic back then! On Windows NT, PortTalk or Port.dll can help accessing the LPT ports. The programs using it can still be 9x compatible, afaik.

Hi everyone, Here's a picture I'd like to share with you for your amusement: MSD gets confused on my XT class machine. 😉 While XMS might be possible to simulate on an XT (the emulator PCE did it), Extended Memory is a bit tricky with the limited number of address lines.
