Heya everyone... just thought I would try to get somone else's opinion on how I can go about changing the batteries in SNES game carts... they seem to be attached in some way inside the contact arms.... I just want to know an easy way to change the battery out with a new one

On the topic of batteries... does anyone know hwere I can get a bulk lot of CR2032 batteries???

AND Does anyone know where I can purchase a bulk lot of NES 72 pin connectors, I ran out of the ones I had and I would like to just get a large lot of them so that I can fix NESes whenever I come acorss a broken one or whatnot....

Any help would be great

Thanks
