I have a physical battery relocator for one of my games (the kind with the two fake plastic AA batteries connected by a plastic bar in an H-formation that go into the first and third slots of the on-board battery holder.) I noticed that the battery holder at the other end of the relocator for the 3 AA batteries has the batteries alternate: +/-, -/+ (middle), and then +/- again. However, the holder on the board that the fake batteries plug into has all 3 AA batteries facing the same direction (the middle battery is NOT reversed.)

When I tried using it, none of my settings are preserved - it always restores factory settings. Should this still work? Can I salvage it somehow if not? Yes, I know about the NVRAMs but it would save me a few bucks if I can use this one I already have until I'm ready to get those.

What would they be for a FH, T2 and TZ?

That's what I expected, but the holder doesn't work. The holder is brand new although I have had it in the little box it came in for about a year before trying it recently.

The fake batteries have a + at one end of the first fake battery and a - at the opposite end of the other fake battery. Since the two batteries are designed to plug into the fist and third AA battery slots (with that H-bar connecting them in plastic), this means that + will go to + and - will go to minus regardless of the orientation of the middle battery slot. And yes, I do have + going + and - going to minus - I double-checked.

Will check back for further input later tonight.

Thanks folks ... and thanks in advance, folks!

And further yes: the batteries are brand new and work in other devices.

*THAT* did the trick! Thanks, DCFAN - and everyone!
