Hello! I'm a creator of this bank editor (I have come to here by MusicallyInspired's invitation), and I came to ask the full specification for SCI PAT file to allow me to add support for it into my bank editor. Can Sierra, or any other who has it, send it to me?
P.S. About BNK: there is support for two types: AdLib and HMI. There are has differences and HMI banks usually can't be opened by most of BNK editors. Support for those files is experimental (especially writing case, reading works fine, but writing works incorrectly yet, I'll fix that in nearest time)
