Re: Sidam Asterock wont coin up

I had to post the rom out to the owner on my way to the usa the other
day.. stupid airport letterbox would only take flat letters (not a rom
in a padded envelope). So i had to post it back to England from the
usa.. it only arrived a few days ago.. i'm waiting for the owner to tell
me if it was successful.

Andre... the instructions are right there, make it yourself and burn it!
