I just got an R4 Vol. 2 from Gamebay for Christmas, & i love it. It is the easiest thing i have used. If you do get one, get it from Gamebay.com. Free shipping & a price of $20, not sure if its a clone or not (confused by many answers that were posted when i asked), but it works like the real thing with R4 firmware 1.18. The R4 firmware itself isnt being updated anymore, but the YSMenu is (search it up if u dont know what it is). I use the R4sauto method for both firmwares, & with both of them, every game i have tried has worked. The newest game i have tried & play is probably Phantasy Star Zero (J), works great on R4 & YSMenu. EVERY game i have thrown at the R4 1.18 firmware has worked. So if u do decide to get one, I dont know about the other flash carts, just use the R4sauto method & update ysmenu every time its updated.
