this may sound stupid but i see the on/off switch on the controller but nothing happens do i need a PSU… sorry for stupid questions i just dug my brothers VB out of the attic.

you either need a battery pak or an ac adapter. you attach them to the back of the vb controller. does your vb controller have a battery pak?

no i don’t… i just assumed that was a memory slot

An AC adapter would be the more desirable of the 2 power supplies if you plan on playing any more than 4 hours or so
