is there a formula for the CRC on m3 sav's or game saves?
like is it game dependant?
are there any tutorials to finding out how to calculate the crcs for saves after editing?
Just rar the save and winrar will tell you the crc...
You could luck out and find the save is a bios crc16 but if it is not I am afraid you are in need of some assembly skills.
BIOS crc16 is not your standard crc16 so either implement one with the data from here:
or this is what I use in hex workshop (the bios crc16 is used in the hash of the header):
you wouldn't happen to have an example of how it's calculated using crc16 would you fast6191? i.e for a game
Those options are for the BIOS crc16 function, the only time I ever use it is when I mess around with the DS rom header:
at 15E hex is the BIOS CRC-16 of 0 to 15D hex.
If you want to write an app to calculate it the link I gave details how it happens.
