Cool thanks, nice to know the Liter one works as I'd heard some posters (on Reddit - possibly not the most reliable source) say they weren't suitable.
My original one seems ok now and has no bulge at all but I want to have an official backup to keep the Win going as I love it and can't really justify the expense of the Win 2. I've had to disconnect it a couple of times over the last two years as the calibration drifts and it shuts off early - lost my save in Wonder Boy 3 because of this!
Did you mod yours to keep heat down? I always play with the fan on full and never charge while it's powered on but it still gets pretty hot. It's the later revision with the aluminium lid.
