I don't see any need for a translator. Japanese folks won't know whether the program will work on non-Japanese systems. But normally, if you try using a Japanese program on a Win9x system without OS-level Japanese language support, you should still be able to use the program, you just won't be able to have it display the text in the program. But, if you don't know Japanese, that wouldn't make much difference anyway. A little trial and error can usually yield the desired results, either way.
Anyway, if anyone here tries it out, don't forget to get the patch on their free downloads page (in case the main download hasn't already been patched).
Also, make sure you've got plenty of disk space (over a gig, iirc) before running the program.
Still quite busy.
(Yes, I intend to deal with that stuff eventually, but kinda can't just yet, sorry. :/ )
