Oh so that was is a worm attracting stick

idk i feel like they're different enough, especially later on comparing snes and sfamicom, which only differ in design, with no technical differences

There are a few notable difference between the 2 tho, on the famicom controllers are non detachable, and i think the nes is missing a few pins on the cartridge connector, so it can't use things like in cartridge audio chips

Technically it's famicom that was released in 83, the nes wasn't released until 85 but only in new york, and only was available elsewhere in 86
