VT368
A platform apparently used by Jungletac in their recent handheld consoles, such as the dreamGEAR My Arcade Portable and Reactor Handheld.
(my source for this is V.R.Technology's website, which depicts a Jungletac HiQ Classic as an example of a VT368 console)
Seems to be backwards compatible with NES and Jungletac's enhanced-NES 8-bit platform (VT09?).
I'm not sure about the distinction between VT368 and VT369. VT369 may be the version that added NES/VT09 backwards compatibility.
