Very weird cart here. Given the look of the plastic of the casing, I’d say pirate more likely than repro.
Thanks to NESMASTER for submitting this one.
Upon further examination (mainly due to a few comments) it seems that this is a repro. Still, i thank the casing makes it look like a repo, but evidence indicates other words. This is part of the gift/curse effect of the NES hombrew scene. It allows us to get our hands on games that would otherwise be impossible to own, such as Earthbound 0. However it does make collecting somewhat more confusing.
Still, definitely worth it however.
