I can't get this ASM hack to work. I used the fftorgASM packaged with fftpatcher .480
I used a clean ISO and used fftpatcher to make the empty slot above short charge ("unknown") learnable by time mages. I replaced short charge with "unknown" and gave it a name in fftactext. I patched my ISO.
I then used fftorgASM to patch my ISO with the "empty slot above short charge adds 25% bonus skill hit" hack. I started the game, learned the ability, and set it as my support skill for a time mage.
Before I patched the ISO, my time mage casting haste on himself would have the success rate of .69x.69(5+180%)=88%. However, nothing changed after applying the hack. Same result with other abilities. I applied other hacks and they worked just fine. I tried using xml generator to make a new xml from the hack posted in the forums and it still did not work, although other hacks worked.
Am I making some embarrassing fundamental error?
Eh, it must be my ISO, because the "precision" skill in FFT+, which uses this hack, has no effect in my game...
