I had the “XPG” version and the headgear version when I was little. Of course it was just a cheap knockoff of the VB that basically stripped the VB of everything cool and just resulted in bad red/black LCD games. Pretty awful system but it’s fairly nostalgic for me.
Unfotunately, I do lol. I traded some action figures to a mexican kid I rode the bus with back when I was a kid for the headset version. This thing was uncomfortable to use and the cartridges unreliable. I have Daytona USA, Battle Arena Toshinden, and Nights. Unfotunately since these are lcd, they have degraded and the only game that still works is Daytona USA. I also remember only really giving any kind of game time to Daytona USA because the other games were just monkey garbage.
Have 3 R-Zone headgear (one brand new), 3 XPG (1 brand new) and 1 brand new Super Screen along with most of the released games (both brand new versions and open versions). It’s a pretty crappy system but also pretty unique.
I was a proud stalker of the discount end caps at Target in the 90’s with R-Zone and Game COM being two things I picked up. I had the star wars handleheld bundle, it was neat, but at the time there were only the bundles available, no other games.
