Can an official N64 Rumble Pak be soldered to work without a battery? [closed]
Solution 1:
There appears to be a few forums and videos showing that this is possible. One video includes this one:
It seems all you have to do is de-solder a 60Ω resistor that is found within the Rumble Pak, and solder the same resistor into a different location.
An additional site that discusses this can be found here. Using the image found on it, I illustrated what you need to do. It doesn't seem that hard watching the video above.

Note that it was pointed out in the video that having too many controllers with a modded Rumbled Pak could short out the console. It was suggested that you have no more than 2 controllers at a time with a Rumble Pak like this connected to the same console.
