Semi-confusing explanation:
The patchfile in the iToS patch folder makes calls to the sound file in the data folder, what’s missing imo, is the jToS’s patchfiles ‘call’ for the new sound.ipf to respond to.
In short, iToS’s patch file needs jToS’s patchfile’s updated sound.ipf check, else it won’t work.
Which is why atari and co. unpack/repacked/etc said files.
