After going through three flashcarts, I'm done with all these Ebay sellers who have absolutely no idea how to work what they're selling or are just a parent of a eight year old and really just want to sell it. Also yes I have seen "Which flashcart should I get" by Rydian. But because I'm not natively English, I sometimes just misunderstand things and I want to be really clear that the R4 I'm trying to get will work with my consoles. I have two DSIs, one being a DSi XL 1.4.5e and the other being a DSi 1.4.5u. Will the R4i Revolution work with my consoles? Also is the retailer I'm getting this from a good reliable retailer? All input and any input is very appreciated.
