Actually, it's more grey area than you think. See 'interoperability exception'. It does break copyright and EULAs however.

As legal as archive.org collection of DOS games playable in browser, by which I mean not at all. But defunct game studios rarely sue.

i actually developed the project to play my own game dumps remotely via VPN from my home server; making it publicly available is not legal and will be consequences:)

Thanks for pointing this out! i found the issue and fixed it

I won't be surprised if we see mention of this by the end of 2026.

the GS was the biggest one, i emulate it in WebGPU compute shaders, and texture sampling alone takes about a third of the GPU time, so at 2x GoWw is gpu-bound on an integrated gpu. On the cpu side, VU1 microcode and the GS front end each take roughly a quarter of the time, so both run on their own threads. another one was synchronous GPU readbacks in GT4, and about a thousand tiny effect draws per frame in GoW2 combat batching and caching fixed most of them, and it holds 60fps at native resolution

The games themselves are copyrighted, no?
