I know that you can just open up R4CCE and choose to add the ROM as a new game and find it out, but I'm interested in being able to manually find it for myself.
Example:New Super Mario Bros (U)
A2DE 77DAD131
Open the ROM in a hex editor and you'll see right at the top: (spaces and 00's displayed as _ for visual aesthetics)
This gives you the 4 "main" Game ID characters.
Example:New Super Mario Bros (U)
A2DE 77DAD131
Open the ROM in a hex editor and you'll see right at the top: (spaces and 00's displayed as _ for visual aesthetics)
Code:
4E 45 57 20 4D 41 52 49 || N E W _ M A R I
4F 00 00 00 41 32 44 45 || O _ _ _ A 2 D E

Calculate the CRC32
Do a bitwise NOT (or substract the CRC32 from 0xFFFFFFFF)
