Ok. Its not so important.
Here is
fwchecksum.exe.
It will calculate the (new) 16 bytes checksum and the (new) sum correction value. It ignores the current 16 byte checksum and sum correction values (the old ones still present in the file). It does this for three different areas:
In other words: when you change something in any of these areas and run this proggy you can replace the 16 bytes + sum correction value and it should flash without error
.
I'm a bit sleepy at the moment so I hope I didn't make any mistakes
. Fingers crossed...

PS. Currently I'm not actually doing the scrambling stuff which limits this proggy to this revision atm.
[edit] Almost forgot: the flash dumper (+script) works!!!
