I'm nearing finishing up work on Resident Evil. I've moved on from the games, but I forgot to post a small guide of sorts concerning Capcom Europe. It's been in my working documents for a while, so I'd rather clear it out and post it here instead.
For Microsoft and Sony games published by Capcom Europe (CE Europe), they mostly all adhere to a specific back item number formatting. Here is an overview explaining it.
This does not pertain to earlier published games from companies such as Eidos Interactive, Ubisoft Entertainment, or even Capcom Eurosoft. Earlier items such as some regional variants for Resident Evil 4 for PlayStation 2 do not adopt this formatting, though. Other games around this time may not feature a back item number at all. By the next generation, however, it is the standard. Games generally share the same base number. So, for instance, nearly all copies of Resident Evil Village for PlayStation 5 share the 62000 base (62009 for SteelBook.) Before this information, a prefix is attached depending on what kind of release the item is. After this base information, a regional suffix number is attached. This suffix number may be attached with another suffix based on re-releases such as with the PlayStation Hits line or with certain special editions like the lenticular slipcover items.
