Interesting, thanks! Though our set up is a little weird because we're actually supplying the 5V the NES needs directly from a PSone screen. The freezing happens so so so so so so infrequently, that I don't think it's a power issue. It's just a rare problem that I'd prefer to never happen again, hence soldering the cart directly in ~_~

~*~*~*~careful soldering~*~*~*~ ... Yeah I've already got a new connector, but on the rare occasion, it still fails. Is there anything else that can cause it to lockup and freeze?

I'd imagine it's just the contacts between the cartridge + the socket, right? So theoretically if one was to solder the powerpak directly to the board of the NES, would it never freeze? I'm looking to make our live setup industrial grade smile
