EDIT: I have recompiled the game this time not selecting the vanilla difficulty, and the problem with the crashing fights are solved.
Got a question for anyone who might be able to help.
I have gotten everything working flawlessly however ive run into a slight problem trying to get the huge materia from the corel reactor. The problem is with the 5 fights on the train before you stop it from hitting corel. the first battle is 2 gas ducts instead of one...so the battles arent setup correctly and when you get to the last train car theres a battle swirl and then it crashes. I have also had the same problem with getting a few of the summon materia as well..like kjata..and the alexander fight wasnt the fight with snow it was a fight with these flying green enemies with like 800 hp.
Anyways maybe someone has an answer or a solution to the problem, ive only seen one thread about this subject and it was never replied to in a fashion that would solve or at least let me know what the problem is.
