If so, then it's very likely that it's just another rebadged AtGames device (pretty much what I guessed in the first place ) - i.e., designed and made very far away from the UK... That seems to be all that Blaze sells.
AtGames has licenses from Sega and Atari, that I know of, off of the top of my head.
Meh, that's all we need, a "successor" whose hardware is at the same level or even weaker than the original's. I'm sure there are a bunch of Chinese handhelds out there that easily supersede this for the same price. It's probably already using a Chinese SoC anyway, like an Ingenic Jz4755 or similar.
