I bet the text changes are a reaction to those older hacks (like on the Arcade Action) where they completely redid the graphics but didn't bother to change a word of text, which kind of completely undid all their efforts to disguise the games they were ripping off when the main character in "Destroy I", for instance, is still called "Mario"
so the makers of these games probably thought that to be on the safe side they should change *all* the text, even if it made no damn sense.
I'm still not sure about whether some of the other games on the Gun King are hacks though - I'll upload videos at some point (tomorrow probably), theres one called "Tank" which is very similar to Battle City but some little details are different, which makes me think its probably a clone rather than a hack - sound effects seem different, the tanks move slower, animations still play when its on pause, stuff like that. and another, "Square", which may or may not be a hack of Tengen Tetris..
Xmas Gift is another weird one too - my first instinct would be to say its just a modified version of Nice Code's Mad Xmas, since the concept and most of the sprites are the same, but the coding is clearly completely different.. its the exact opposite of the usual Waixing versions of Nice Code games, where they just change the graphics but leave everything else the same.
oh and I just noticed that pixel-dude on the packaging actually *is* from one of the games, he's in this version of Boxworld.
oh yeah, and i found some proof that Canhui Toys just rebranded Subor products - a HK distributor's Alibaba page showing a Canhui branded version of
this Subor famiclone.. but the company seems to have completely vanished from Alibaba in the nine days since I found it. grr. you'd think I'd have learnt by now to save a local copy of anything interesting and pirate-related I find on the internet, they always disappear eventually.
so I suppose the reason they removed all their Famiclones from their website was that their relationship with Subor broke down for some reason or another. but frankly Subor confuses me anyway. if you google their Chinese name you get the websites of about five different companies all claiming to be Subor, I've no idea if they're all divisions of the same company or if only one of them is the real Subor and the others just ripped off the name.
http://www.suborchina.com seems to be the one that makes game consoles though.
