When I began to add and edit my Nintendo DS games on vgcollect, I found out that that the item number from the cartridge often differs from the item number from the packaging.
For example:
- Ace Attorney Investigations: Miles Edgeworth, I have NTR-C32P-EUU on the packaging and NTR-C32P-UKV on the cartridge.
- Advance Wars: Dark Conflict, I have NTR-YW2P-FRA on the packaging and NTR-YW2P-EUR on the cartridge.
My guess is that different packagings can hold the same cartridge: Packagings are more region specifics.
For Advance Wars, my packaging (as the manual) is in french (hence the -FRA), but the cartridge is multi-languages and I think it's the same cartridge in the others european packagings (hence the -EUR).
So I'm asking which item number should be in the vgcollect database (for me, it should be the packaging item number).
I think my questioning should apply to others games/packagings, so it may be an already solved issue, but I didn't find an answer in the style guide or in the forum, maybe it should be included in the style guide ?
