> GTA SA, GTA III and Vice City are all running live inside the same process. VC renders into a GTA III texture, and GTA III renders into a GTA SA texture. Every layer is playable in real time. Built using modified re3/reVC and librw.

> THIS ISN’T A VIDEO PLAYING ON A TEXTURE. THE FULL GAMES ARE RUNNING LIVE INSIDE GTA SA, IN THE SAME PROCESS, NOTHING IS STREAMED FROM ANOTHER PROGRAM.

That's badass.
