I really wish some wise company would make a new PCE/TG16 portable, like they are with the new NES and Genesis portables. I mean, Hucards are nice and small anyway, and since the TG-16 is such a basic design (3 chips I think), it wouldn't be that hard. Imagine a unit about the size a gba micro (roughly) that lasted for ten hours on three triple AAA batteries and played everything on a nice, shiny new full-res screen.
After all, they Geny one is launching next month, and there are several NES ones. Why not a Turbografx / PC Engine one? Even if it was japanese only (which you would think it would be given the popularity of PCE over there), we could import one....
Of course, I got my Turbo Express for $50 at an expo, so I can't complain.... :-"
