I want to know the answer to the following question:
How did Nintendo say an NES and SNES could be used on the same TV?
All the background I'm provided with is that "While Nintendo never released an adapter for playing NES games on the SNES (though the instructions included a way to connect both consoles to the same TV by either daisy chaining the RF switches or using AV outputs for one or both systems), the Super Game Boy adapter cartridge allows games designed for Nintendo's portable Game Boy system to be played on the SNES.". Is that enough to answer the question?
Answer: yes
