This reminded me of work I did for Proton/Wine a few years back: finding a buffer overflow in the Rockstar Games Launcher installer NSIS script, having to implement an ancient deprecated Windows named pipe mode that RGL uses, reverse-engineering the VRAM display/detection in GTA IV…
Thanks for the often unrecognized work that goes in creating something like this.
Once in a while I try some of my father old games with my steam deck ('90s game like the OG Colin Mc Rae Rally or the early Need For Speed games)and I'm impressed how they work with basically no issues on current-gen devices.
If anyone wants to do this kind of reverse-engineering for a living, we’re hiring at CodeWeavers: https://www.codeweavers.com/about/jobs
