So I have figured out my problem. I'm going to start a new topic about it to help anyone else in that situation. My problem ended up being Windows Data Execution Prevention (D.E.P.) was shutting things down when certain mods were active. I had finally given up on working on this for a while, and was messing with getting some of my other games installed and Final Fantasy XIII wouldn't start either, and after a few hours digging into that, someone recommended checking Windows Event Log, and I found the error there, googled it and found out it was related to D.E.P., shut it off, and bam the game worked, so I thought, I wonder if that could have been FF7 problem, and sure enough! Now Ive got everything working and even added in the updated Remako mod and the Echo-S Demo, and everything seems to be working! (Granted, I'm at work and am remote controlling my pc at home to check but other than not knowing if the audio is working the game booted and I was able to play for a few minutes. I wonder if D.E.P. got an update or something? This was working fine a few months ago. So could a mod mark this as solved for me? Thanks!
