Wrong battery and hot glue makes me think it's not the original battery.
Maybe if I put a meter to it and get 3V I should just leave it...
A separate question, I never noticed all these years the "Barney" converter I use to play Japan games on my TG16 has a picture of a PCE being used with American games...
I've never had a PCE, I have a Duo-r and these adapters do not fit in the hucard door.
Does the adapter work in reverse of how i'm using it as shown on the sticker?
I'm guessing yes but like I said, I can't test it for myself with no PCE.
