is it worth this much i have always wanted one www.aliexpress.com/item/Ique-n64-tv-game/1132852374.html
The only games available are in the Chinese language and have to be loaded onto the thing from mainland China AFAIK. There is also a very limited amount of space on the thing so even if you were happy to pay full price for everything you couldn't have it all.
You have to buy all games through their download-service (buy point cards and then redeem them for games, added via USB cable). They do have some nice boxes for sale that contain manuals and all though, they're super cheap quality but it's a fun collectible to have. Around 12 or 13 different games were released with those boxes, but half of them are quite hard to find.
I've bought a few and would say they're generally worth £45-60, depending on condition. They're a nice bit to add to a collection, but unless you're buying a used one with some games already loaded onto it, they're pretty pointless. Also agree on the quality being piss poor - I received a pretty grubby one and took it apart to clean it and the paint came off the buttons when they were submerged in warm water.
