Final Fantasy Hacktics

unfortunatly it's not working for me. I get a quite a lot of mixed chars, but the critical thing is that it is stuck before the first fight. I use mednafen emulator 5502 bios, i tried to patch with several US PSX isos with applyppff and also with ppf-o-matic.

what am i doing wrong?

ok it works in other emulators, i just read a comment that mednafen is not auto correcting bad sectors when patching a ISO, after running ECCRegen over the patched ISO it works fine in mednafen too.

thank you very much for this good work!
