Although, this might be unrelated, I get GoMMC ROM corruption randomly from
running ADFS hard disc images that have lots of files in them. You know when
it's screwed when you get the infamous "Broken directory" and CTRL+BREAK
gives you garble and a power cycle I get the same message about the GoMMC
ROM is corrupted. I repair the ROM and go through it all again, the same
directory is now fine and I sometimes go for months with no trouble. I've
got 0.9 firmware, perhaps I need to send it back to be flashed to the newest
version. I would like a way of preventing the ROM being overwritten as it is
a complete pain to remove the jumper to clear the ROM and then re-program
it.

Cheers
