Re: Checksum questions



Ya checksum, at 0006+0007. Is the total from 0008 to the end of the program.
If you want to send me te before editing, and after editing, I'll run them
thru my editor and send them back with the right checksum, maybe that will
help.

Didn't tunercat have a checksum program?.
I just checked he has a 30 day evaluation program, If you doing many might
be cheaper just to go this way, or get a editor, both the Tunercat, and
GMEPro also do auto checksums
