> I think Ryccardo is correct that the digit in the filenames after the product code is the ROM revision; its 0 for all ROMs except those that had later revisions (Japanese Red APAJ1, Green APBJ1, and Yellow APSJ3).
> As I understand it, Nintendos product codes printed on cartridge labels, boxes, and manuals reflect revisions or different print runs of those materials; the only reliable indicator of ROM revisions is the code printed on the ROM chip itself. For example, my Pokémon Stadium cartridge has NUS-NPOE-USA (no revision number) printed on the label, but the ROM chip says NUS-NPOE-2, and it is in fact revision 2 (with purple Jynx). Conversely, a code of DMG-AAXI-ITA-1 on a cartridge label doesnt mean that there was really any revision to the Italian Silver ROM.

I see. Thanks for the info, I wasn't fully aware of that.
