Hey Phyltre, I have the music patch working fine on mine. I'll list what I did to get it to work (I've done it a couple times so it should be fine).
1) extract the FF7 1.02 patch (with the ff7.exe and FF7Config.exe) into the X:\Program Files\Square Soft, Inc\Final Fantasy VII
2) use SaiNt's hi-res patch on the 1.02 patch (it should work fine)
3) use Ficedula's music (go into Cetra & apply music patch - make sure you're in the right FF7 directory
4) then i use the minigame patcher (very nice btw dziugo)
then it all works great
I'm not sur eif its because of your Reunion patch or something (i don't use it since i like the cutesy characters).
Hope this helps.
Here's the problem I'm having. With the basic 1.02, I can play the game fine without any graphical problems. When I apply only saint's hi-res, the game crashes before the opening screen unless I enable one of the nvidia card fix under ff7config. When I do this, I get the green-grid problem (I researched this on the forums) so that I can't even tell if it's hi-res or not.
Now, when I apply the multi-patch (the geforce fix specifically), I can load the game without enabling either of the nvidia card fixes. However, I'm back to step one--the hi-res doesn't work! I'm left with 640x480!
I hope someone has some ideas, personally I'm just about lost.
