Final Fantasy Hacktics

Enough of all of your useless advice, i fixed the problem on my own!

Im playing it on epsxe. And I didnt use a patch file i just patched the ISO directly. I directly edited Gafgarion in as a guest unit during the battle with Queklain and when it comes to the end of the battle the join up screen is there like it should be but the second i push a button the game crashes. Its doing it for any time the join up screen comes in, whether its someone i used invitation on or when one of the guest characters that normaly join you.

Its happening for any event where the join up screen comes up. And the unit im trying to make join me is Gafgarion and ive done before on another computer no problem. Its PSX version. And if i use the disk the problem doesnt happen but the disk doesnt have the changes.

So I used FFTPatcher to change some of the events and one was to make an enemy character join me. Everything was working perfectly on the game but when it got to the character join up screen the second i push a button the game crashes. Then I tried doing the parts where guest characters join me and it does the same thing! Any help would be appreciated.
