So, after a bit of struggling but avoiding messing with any of the game files or mod configuration, I believe I've gotten a step back from where I was previously. Starting FF7 with 7th Heaven would always require launching the game from 7th Heaven, waiting a few seconds, then hitting Enter on my numpad, causing a quick beep and the game starting up shortly after. However, now the game closes after the beep, usually with no crash error message. I did get one once, though, so I do have the contents of APP.LOG to show for it.

EDIT: Re-patching the game using the Game Converter fixed this issue. Now it's back to the problem of crashing at the startup of battles. See here:
