Creator: Dark-Show Uploaded: AssemblerGames Manufacturer Code: 4 Byte ASCII Last byte for region identification: E = USA J = Japan P,X,Y = Europe D = Germany F = France S = Spain I = Italy Manufacturer Code Detection (Pseudo): if old_licensee == 33h AND (cgb == 80h OR cgb == C0h): manu = header_title[-4] manu_region = manu[-1] if region_check(manu_region) == 0 OR manu_blacklist(manu): unset(manu) else: header_title = header_title[0,-4] region_check(code): code = E: return USA code = P,X,Y: return Europe code = J: return Japan code = D: return Germany code = F: return France code = S: return Spain code = I: return Italy return 0 manu_blacklist(code) code = 'CLAS': code = 'DISE': code = 'INGA': code = 'INGD': code = 'ZONE': return 1 return(0); Thoughts: The last byte is region, but for europe there are quite a few codes, which leads me to think the codes were supposed to determine language support Looking at the data however shows patterns with a few exceptions, maybe this was the intended purpose but was badly enforced, and not usable. It looks like there is sometimes a method for the random generation based on bits of the filename. This leads me to believe the code is just a unique region based ID for recognition at a later time. Some more examples of this naming scheme: Code: VZF* Zebco Fishing! (U) Code: VV8* Vigilante 8 (U) Code: VUP* 3-D Ultra Pinball - Thrillride (U) Code: BUZ* Buzz Lightyear of Star Command (G) Buzz Lightyear of Star Command (U) Les aventures de Buzz l'Eclair (F) Final Notes: All codes have a region byte. + Also meant for language identification but not usable. + Thought: After the data changed from being generated from the title to an incremental functon, It's quite possible the code was to be 2b manu + 1b lang + 1b region (X,Y would identify language byte support) Not all of them follow the naming scheme, possibly meaning that someone or some function generated these IDs. (Seems to have moved to a incrementing function to stop collisions, and provide additional functionality) + Thought: Code will not start with a number (It may be a coincidence, but chances were missed to do this which leads to the thought) The IDs can be shared between software versions of the same game. + First 3 bytes can extend through regions with only the last byte changing (*Except for the noted collision) Known Manufacturer Codes: [0] => A22J [1] => A22X [2] => A23J [3] => A2AJ [4] => A2CJ [5] => A2GJ [6] => A2KJ [7] => A2MJ [8] => A2NJ [9] => A2OJ [10] => A2QJ [11] => A2WJ [12] =>
