I stumbled upon this today and thought it was interesting. It’s all the stuff in those e-Card levels from Super Mario Advance 4: Super Mario Bros 3.

I, like pretty much everyone else in the world, never actually played these levels. The thought of hooking two Game Boys and scan in all those cards gives me chills. It would have probably just been smarter to put all those levels on a cart and called it Super Mario Advance 5: Super Mario Bros 3 – Part II.
