Got my SD3 cart yesterday and was looking at references. I noticed dual MASKROMs on a BJ3M board, which does not match any references i can find.

Has anyone else seen a SD3 cart like this? All the online refs i can find are single ROM chip carts.
Ref1 (http://www.mmmonkey.co.uk/japanese-super-famicom-english-translations-conversions/)
Ref2 (http://www.snescentral.com/article.php?id=1038)
Ref1 is a repro and I have never seen a 1J3M Seiken Densetsu 3 to be honest. All were 2J3M or BJ3M, so yeah, this is an original PCB.
Ref1 is a conversion from an original cart (note the Mask ROM part numbers)
Ref2 lists the primary board used for the cart to be the same as Ref1 (1J3M)
Some games come in both single and dual rom versions, Dragon Quest VI and Chrono Trigger are 2 examples I can think of, that I have seen personally. Even Super Metroid has a 3 rom variant.
Nothing strange about that. Both ROM chips have the game's product code on it, A3DJ.
Cool! Thanks guys, was just confused as I couldn't find any info on variations of the board for the game.
