I think it worked after trying it on my gm1.00G PS S80, I found a version change and when I retried it on the gm1.00H PS S80 the version field changed. I'll do the clean.
What should name the file, and who can I offer it too? Since there isn't anyone asking for it, can it just be used for upgrading from gm1.ooF or G if anyone wants it?
Thanks for your help.
