The XE Demo is real. Atari sent these to dealers. But, as noted, its a silver label and technically not a released cart, so I did not include it in the list.
There are also grey case, silver label carts. Football, Jungle Hunt, Pole Position etc were re-issued for the XEGS in that form, but I wasn't referring to those either.
I have the Explorer with the Xenophobe and Deflector reviews. It sounds like they were already available! Unfortunately, they were never released, AFAIK. BTW- Anyone have the RX8xxx catalog #s for those?
Part of the reason for my original question: In the label variation section, Andrew Krieg lists:
Jungle Hunt grey case, blue label
Moon Patrol grey case, blue label
Super Breakout grey case, blue RX8006 label
Never seen or heard of these. Perhaps someone got them mixed up with the grey case, silver carts? Anybody seen them?
