I've been experimenting with writing files to the memory card and it 
turns out
that the textual name of a file in the OSD needs to be in Shift Jis, not 
plain
ASCII.

I created the routine below by examining the file created by SIOCONS, but 
can
anyone do better?

Specifically I will eventually need to use punctuation and special 
characters
such as accented letters -- where can I find more info on Shift Jis?
