I have a top-loading A/V Famicom (model HVC-101). With a NES->Famicom adapter, it's the best of both worlds. I get a clean composite signal with all of the benefits of the second-generation NES/Famicom consoles. Also, no modding required!
Does anyone here enjoy Battle Kid: Fortress of Peril?
My favorite game is Mega Man 5. (Ugh, it's so weird to not type it as Megaman, but it's supposedly the correct way.)
