Hi there!
I'm working on the spanish translation with Ryo Suzuki, but can't do nothing to help at this moment...
I compiled the source from the IDX Generator for Shenmue I, and tried to modify some files of the game, but it always generate a .idx file about 20 bytes, without any content...
I asked Ryo about this, and he told me to post here.
Am I using the correct tool?
Anyway, many thanks for your help!
