You realize with the original R4 you can install Wood R4 officially on it?I've unfortunately bought two bad carts, original R4 and the Ak2i, burned by both of them. Looking at the history myself, without the help of most of the unhelpful here, I found that this card is very well supported and receives updates as fast or faster than most others. A clone of the best should be well above the rest.
And if you want fast updates the R4i Gold supports Wood R4 officially, which means it gets all the fast updates with all the official features, like the WIP RTS. Yes it cost a little more, but you are getting a better card for a better price.
We gain nothing for suggesting a better card and are all trying to actually help you. We want to save you the future headache.
