I'll just say what I said in a topic about wanting this for the PSP, that the better proposition and one that makes the best sense would be someone try to recreate this using actual PS1 hardware, see how close they can get it. It couldn't be a direct port of course, but I'd want to see how much of this a real PS1 could handle, and also maybe see if there are things the PS1 could even handle more of that this holds back on.
