Polarity


there have to be a image like this --o)+ means shielding is +
(look at the little picture left from the plug)

I just see two circuit diagrams.

just plug it into ur GP if its the wrong pol. it just wont work, i wont do any damage, i had an adapter that i didn't know wheather it were rite or wrong so i just bunged it in, it were wrong and just didnt do anything so i made a pol. converter and it works fine
 
I'd be very careful with Crocomire's advice, some people have just "bunged it in" and seen there gp32 never work again, so be careful!

If the adaptor doesn't state the polarity, you can figure it out with a meter or even an LED or bulb :)

eh? A bulb would work either way around. A multimeter would be the best way. If you place the red probe in the centre and the black probe on the outside and it shows a negetive value, it's centre-negetive, and a positive value means centre-positive (as long as your probes are in the right terminals - black negetive, red positive on the multimeter).

And also, you can very easily fry devices by putting the wrong polarity across them, especiually with a high-output (amps, or in this case, milliamps) transformer.

I've accidentally tried turning on my GP32 with the opposite polarity and 4.5v and it didn't do any harm to mine. I guess mine is just lucky :D
