This is a bit of a necrobump (to say the least), but TheHillbillyGamer raised an important question that deserved more attention at the time:
What i do wonder about is this, i see translations for games like The Amazing Spider-Man: Lethal Foes, and i wondered. I have in my collection the famicom and super famicom interface to hook up the Barcode Battler 2, a interesting little game system based soly on scanning barcodes and the cods fighting each other. Anyway, The spider man game i mentioned has extra content on the japanese cartrage you can unlock with this barcode system.
Does the tranlation made here include that extra content?
I've wondered about this too. I've been playing through the translated version of another game, Donald Duck no Mahō no Bōshi (Donald Duck and the Magical Hat), that has Barcode Battler support -- one of 11 games that do. A lot of sites say things like "Additional content could be unlocked by scanning barcodes", but no one ever seems to specify
what that content is.
Well, thanks to
some good research by celerystalker over at Digital Press, we now know more. It turns out that in the case of Donald Duck, the barcodes are basically glorified Game Genie or cheat codes. They do nothing more than let you skip ahead in the game -- quite the opposite of unlocking extra content! Lupin III is a similar case.
Unfortunately celerystalker didn't post his findings about The Amazing Spider-Man: Lethal Foes, so I don't know if that game is a different story. But based on what we're seeing with Donald Duck (and Lupin III), at least some of the claims about "additional content" seem to be urban myths. It wouldn't surprise me if ASM:LF is the same deal, where the barcodes just give you extra health, let you skip stages, or whatever.
