Doesn't that defeat the purpose of the BLW?
Shit... when we were kids, the Game Genie WAS the BLW. As in, we used the Game Genie 100% of the time because there was a better the games works more frequently...
We didn't realize at the time that was because the pins in the system were all bent to shit and not getting a good connection with the games, and both were dirty.
So, to keep my NES original, as an adult.... You just gotta clean the pins. When you bend and boil the pins, the grip is also tighter.... and for me I don't have to push the games down. If I do, it's because there's an issue with the game.
So... the system is still original, and I don't need to press the games down. Double win.
Correct me if I'm wrong, but I believe you still have to take the system apart to install a BLW? So if you're going through all that work you might as well just take the time to clean the actual pins that are in there.
