On some games, there are checksums that aren't part of this tool like Zone of the Enders 1 HD Edition and possibly the 2nd one which uses XOR like this taken from BSD:

[DEFAULT:Save Slot 01 - Update csum]
set [csum]:0
set [csum]:xor(0,7F,1)
write at 0xCC80:[csum]

It also looks like there are some other checksums we haven't discovered as of yet but will take time to decode and decipher them.

Trying this out on my current project now. I know where the checksum is located, just not how to calculate it. Seems to be like other games by the same company where it is just a standard 8 bit checksum. Just can't figure out where it starts and stops adding them up yet.

I'm waiting for a full scan on this Juiced 2 save, but I'm wondering if there's anything else I should be trying. Quick scan failed. In comparing 2 different saves, it looks like the checksum is 4 bytes right at the start of the dat file. There's a bunch of identical data after that. I used to spend a ton of time hex editing and comparing ram dumps to find gameshark/codebreaker codes back in the day. Never had to deal with checksums.

Awesome. I waited like 5 days for a full scan on a Juiced 2 save and nothing. :(
