While I'm never one to stand in the way of tinkering, I'm curious as to why you chose FF7?

There are many open source implementations of PS1 emulators, and the PC version of FF7 is notoriously bad. So from a gameplay perspective, the PS1 version of FF7 is far easier to run an any platform, and is superior in all respects.

Like I said, not discouraging it, just curious.
