Apparently some games uses checksums like XOR from a starting offset and end at a certain offset and the value is stored at another offset like Zone of the Enders 1 HD Edition and possibly the 2nd one for example taken from BSD:There are other games out there that might use similar checksums but eventually there will be a tool that will decode/decipher them and then codes will be made for them.Code:[DEFAULT:Save Slot 01 - Update csum] set [csum]:0 set [csum]:xor(0,7F,1) write at 0xCC80:[csum]
