This pack contains 400 carts according to the latest development database for Nintendo Famicom, I did not create all carts, but only completed the ones that were missing, including some unlicensed, untranslated (now translated) and protos.
There`s a separate file, Sanrio Carnival (Japan) (Translated En), it`s a fixed cart image, just replace it after extracting the main rar files.
Note that Famicom carts have varied formats and shapes, the width and height of them are varied, so if you`re willing to use it, some sizing may be needed.
As always, I`ll upload a full Nintendo Famicom pack in wide screen, with everything sized.
Tiny update: Grab this cart Rodrigo found earlier today!
