Hello friends, I recently came into some new Super Famicom hardware, including two mystery controllers that I absolutely cannot find any information on. I suspect they are nothing special but I'd like to be sure. This forum seems like the perfect resource, full of knowledgeable folks who might be able to identify such things. Please see attached images. The controller is called the "Master Blaster" which really complicates getting a decent google search. I have two, non-functional and one functional but in need of silicon repair. I don't have the means to try and fix the non-functional one. Just wondering if some museum would benefit having these before I potentially get rid of em. Thanks!
