That's what I meant when I said I'd tried it - I tried fiddling the GIME 
registers to shift the display but got completely unexpected results 
when I did. I can shift the display left (eg. set HOFF=2) but of course 
that's no good for me. I need to effectively set HOFF=-2. I tried what I 
thought would achieve that, but the display went horribly wrong.

I'll go into it in more detail and try to elicit more advice when I'm 
preparing the next beta release, but for now I've got other fish to fry 
and I don't want to get hung up on this detail.

Regards,
