Keep in mind the following - 3DS games are region locked, either Japanese, EU + Australia, and US/CAN versions. This region is the only important factor, not your geographical location. You can use a US 3DS in the UK just fine with a UK charger, but, you will have to import US 3DS games as EU ones will not play on it. You can purchase digital games from the US eShop, but you must buy $US wallet top-up cards, these are currency and country locked so again a £UK one will not work.
Regular DS games from the UK will work on a 3DS from any region, including the US. It is only the 3DS games that are region locked, so a UK 3DS game would not work.
No, the 3DS is region locked. You'd need the US version.
All 3DS' are region locked, so you cant play an american game on a british 3DS and vice versa.
There is currently no action replay 3ds, but there is an action replay dsi that works for the 3ds being sold only in the UK. I bought mine on ebay.
Regular Nintendo DS games are not region locked, a UK one will work on a US DSi.
I am not sure, but I doubt it. My friend bought the Chinese TS3 and it crashes on her American computer (that might just be windows though)
Yes I think you can. I think the psp is universal because I brought a game in the USA and i got my psp in New Zealand and it works. Yes you definitely can but the UMD movies are region coded and so if you bought a UMD from the UK and tried playing it on a American psp it would not work
No
