Famicom Cartridge Adapter... On the Game Boy Advance SP?!?

A truly odd accessory if there ever was one. Let’s find out if this product can play Famicom games on the GBA SP. And maybe even NES games? :O Also apologies for the lack of production... EVERYWHERE!! As you can tell, I’m not a film professional. Or an amateur. Heck, I think I failed the beginning class. :V
