So, I think the 86box build is really cool but performance just isn't great. Here's a fork of DOSbox-X with PCX2 support: https://github.com/z2k-retro/dosbox-x/releases/tag/pcx2-v1.0
Enjoy raiding some tombs!
Last thing of the night - here's a wrapper to use PowerVR mode on games on modern Windows. It's designed to work with the ddraw.dll which comes with DGVoodoo2 - drop the two files in the same folder as the executable in Windows 10/11 x64 and you should be able to run it in PowerVR/PowerSGL mode. I know others have tried this (or are working on it currently) but with all the time I've spent on this it felt sensible to make this too. In testing it's essentially identical to the output from the real card.
To be clear it's made with the research done for the 86box version, the code released by Imagination, and a adaptation of the drivers written by Claude for this wrapper. No other wrapper projects were used.
