While WebGPU is making progress in browser-based graphics, emulating the complex interactions between the RSX and the Cell processor remains a monumental challenge.

These sites typically do one of two things:

But for now, that dream remains just out of reach. The PS3's exotic hardware and the security limitations of modern browsers create a perfect storm of technical obstacles.
