I remember years ago back in the day when the N64 was in its prime, I read an article in a magazine that showed you about some simple soldering to an N64's crumble pak circuit board eliminated the need for batteries... the pak ran of the N64 as most unofficial ones do.
Now, I'm a collector and I like my official rumble paks, plus its frequency is patented which is why no pak rumbles quite like it.
So I ask, does anyone know about this soldering? If they do, I'd love to know how- I'm getting sick and tired of those damn batteries!!
