Yea I’m not sure of OP’s ability and the requirements for games was vague. But IPX isn’t that big of a hurdle, DOSBox has an emulator for it: https://www.dosbox.com/wiki/connectivity
Bigger issues would be sourcing and playing some of these games on modern systems at all. And some dedicated servers can be a pain.
This sounds like shaders used in graphics pipeline, which is something you code. So probably using a LLM.
