Question about the Aladdin Deck and the games it had.

Apparently the Alladin deck will work on all region NES consoles, but I want to double check.
If i bought one from the USA would that work on a UK NES console?
And what about the Alladin Deck games from America, would they work plugged into the alldin deck thats plugged into the UK NES.. ?
I guess im asking is both the Alladin Deck and all it's 7 games playable in every Region, so like no region lock or anything..? 

There are two versions of alladin. One with a manual switch(v1. 1) and one with no switch(v2. 0).Both allow you to work around the CIC chip in NES, allowing to play regardless of your console region. Keep in lind not all games do region testing and needed adjustments. I know fantastic adventure of dizzy does this so it should be safe to play on any console. I recall Dizzy the Adventurer also doing so. 

hmm..? thanks for reply, not decided to buy one, I mean I wouldn't be able to use it on a Retron 5, so it'd be more like a collection thing, rather than being able to using it.

That ia true. Since alladin was made to Interact with CIC in the NES, it cannot be used on clone consoles or clone consoles that lack the chip. It also wont work on TopLoader NES, having a possibilty of frying the console.
