Hiya!
I was browsing the web and found something about the XGP, XGP mini and XGP kids from GPH. I had never heard of those machines, did they flop? Are/were they any good? Is it possible to still acquire these somewhere?
Gamepark (not GPH, that's a splinter company) went bankrupt and never released any of these. The XGP Kids is alleged to have been released as another product by a company (Gambros) who bought the IP. It's not a very interesting product given that it's basically GP32 hardware with a lower resolution screen.
