Hi guys, ive been reading fro many hours trying to get my friends clone R4 (R4i Gold upgraded revolution for DS v1.4) to work with no avail (only super old games work). Now he and I are interested in purchasing a genuine R4 or similiar system but cannot find any reliable sources to purchase from. Ive found a couple of threads here but seem to be quite old and many of the sites are not available or will not ship to the UK. The only promising site i have found is this: http://www.r4ds.net Real or Fake? As they offer good prices and free shipping to the UK. Also i am totally confused with all the different versions of firmware and compatible systems. I need a R4 (or similiar device) for my Original NDS and a DSi XL. From that site i have figured that i need a normal R4 DS and a R4i-SDHC V1.4.1 (red pack) My DSi XL is v1.4.3, will the R4i-SDHC V1.4.1 be compatible? (i think there is an update but would like to make sure). Or should i forget the R4 and get an M3 or Acekard or something else that is easier to get hold of (are they easier to find though?)?
