I was beginning to wonder what these things look like or if they were an urban myth, but I finally found one- I guess these are the ones to use with the TV tuner and SMS cart converter.
The thing powers up only briefly and gives me a dying NES toaster flashing screen with start up and then black screen (like every 2 or 3 seconds. ) I suspect it needs to be cleaned or that I need fresh batteries or a power supply for it. Let's hope- after that PCE GT I got that looked great but had a dunce screen, I may have a handheld console curse.
Anyone else notice how rare these are? I believe that for the 30 or 40 GGs I've seen/found in the wild, this is the first flat screen one I've come up with. It's for keeps, BTW.
