Ha, it seems i'm at a loss for words. I had char.lpg AND all the minigame .lpg's in my data\ffprp folder already...
Did the new installer place them there?
Did ff7-prp.exe, when ran, extract them and place them there?
I don't remember when i saw them there, before or after i reinstalled it, but they were there, already named as such.
But, regardless: i'm sure that renaming and overwriting and using ff7.exe wasn't the intended method, but it seems to be working... for now. Just make sure you're using the 1.02 exe; less problems.
By the way, GeForce users:
If you're having problems with random crashes (although it doesn't seem random, it's always three minutes before you get to the next save point...), roll-back your drivers. The latest drivers (dated december 2007) fudge ff7.exe up. SO, roll-back to at least the June 2007 drivers, otherwise, ff7 will be an unnecessarily frustrating experience with all of the crashes, graphical glitches, and overall, gayness.
No, you stop!
