I'm just going to leave this here.
FFT Complete only changes the in-game text to match WotL. FFT+ uses Vanilla text, but is rebalanced and is slightly more difficult.
is it possible for me to combine both patches into one?
There isn't a version that combines both yet, sadly. :(
what if I just ran the FFT+ patch over the Complete patch?
Edit: Actually, I think I'm gonna try that...
That would undo the script changes to the PSX script, I think. Also, try not to patch one patch on top of another. It can cause some pretty severe bugs. If you have any questions/comments, come onto IRC!
Yea, it was all good until the battle started. Ramza became Angel of Death! hahaha
Alternatively you could try FFT1.3 easy type or Parted Ways patches. Both have increased difficulty or new gameplay and have the WotL script incorporated.
