famicom castlevania 3 on NES

Has anyone ever tried playing the famicom version of Castlevania 3 on a NES using a converter/adapter? Does it work? I'd guess it would work sans special audio.

The reason I ask is because I want to try playing Joy Mecha Fight on my NES, but I don't want to spend the money until I know it works. I just figured more people would have tried it with Castlevania already.

If you connect it with a good adapter, it'll work just fine. You can even get cartridge audio if you connect the correct Famicom pin to your NES expansion port. I think one of the cartridge pins goes to the expansion port and you could then use a jumper from there to take it to the audio expansion pin. That's what I remember atleast. I never played any famicom cartridges myself.

I don't know if I'm willing to go that far for a couple of extra channels of audio. As long as the game plays the same, that's good enough for me.

The game should play the same obviously. To get extra audio for Just Breed I had to add a RC circuit and a wire in my NES, and a wire on my 60 to 72 adapter. Maybe only one wire on the adapter and one wire on the bottom connector would have been enough, but I haven't tested.

I bet the game would work pretty bad on a PAL NES because the VRC6's scanlines counter rlies on 133+2/3 cycles per scanlines, which isn't the case on PAL.

Don't the middle pins on the NES cart connector correspond to the expansion port? Shouldn't there be an easy way to just mod the famicom connector so that the proper pin connects to the proper lead on the cart? Or is that what Bregalad was describing?

This is what I'm describing, but there is no sound in pin on the NES's cartridge connector. You'll have to tie sound in to the expansion port, and then either :
A - Connect sound in to the sound output from the NES via a R-C lowpass filter (confirmed to work perfectly for me).
B - Connect sound in to the "sound in" pin on the expansion port. I don't know if that works well, or if that works at all.
