given that they list so many arcade machines and made the Game Zone 2, I'd bet they're behind the super expensive arcade machine Famiclones that Argos (among others) sells in the UK, which have similar game selections...
Their
alibaba page has some interesting stuff too - they seem to have been responsible for the
Mega Joy for example. and they list an
AtGames arcade stick too.
All their
handhelds actually seem to be Cool Boy variants by Subor btw (one even still has a Subor logo on it - no clue if they had some hand in making them or are just distributing them), except
this which I have no idea about. Game King variant? Brick Game type thing with fake cartridges?
