JP symbols are all in the same position, but that was expected. So that's it all checked.

00 is a space, 01-0f are symbols (02, 08 and 0f crash).

10-1f are numbers and []<=>?

20-5f are most likely "system?" commands, in most cases they crashed due to improper use probably. 41 (A) is a dialogue box and 52 (R) is a new line.

60-7a is the alphabet with 60 being an @ maybe? bit hard to decipher that one. 7b and 7f crash. 7C = yen, 7D = nothing? and 7e = ^

80-85 crash. 86-FD is the normal japanese bit, unaltered. 90, a0, fe and ff crash (blank characters in the normal set).

There is a roman alphabet available which doesn't seem to issue commands, it is all caps though. It's hex 61-7A. If DISK and ENDING are written in caps, that would explain them.
