No need to delete or lock it if you win the auction.  It'll fade away eventually on its own.

I just took out my Stack Up converter (modified it to accept Famicom cartridges [removed the tabs and ground the sides down a little), and tested Castelvania 3 (Akumajou Densetsu) in my NES (using a Game Genie as an extension) and the comparison is not even remotely close--the NES cannot at all produce the audio that is on an advanced audio game like CV3.    Guess I'll need to buy another Stack Up for my collection now  (the tabs were what screwed the chipboards in place).

Solder pin 45 from the Famicom side to NES pin 18 on your StackUp converter with a 100k resistor and 1 uF capacitor.
Then open up your NES and solder pin 3 and pin 40 together on the never used expansion slot

and there you go, extended sound on your NES!

Very interesting.  I may even try it, though I'm plenty happy with using famicom games on the famicom and NES games on the NES.  Though compared to a Twin, the NES still has no microphone or way to play Famicom disk games, which has quite a few key famicom games IMO.
