Hi there: I recently bought an R4isdhc. It works perfectly fine and I am very happy with it. My fiance then decided to buy one themselves and we've been having nothing but trouble with getting a working sdhc card for the R4i cart. The card in mine is a samsung sdhc (which seem to be hard to find). The card we got with the new R4i (which we got from the same site) came with a sandisk card and that didn't work in either cart. We then decided to pick up a cheap integral sdhc card, this card boots up and the menu's work fine but takes ages creating save files. It get's to 90% on loading a game then stops and nothing happens after that. I was wondering if anyone had any advice on what we could do to get it to work. Also if anyone knew a list of working sdhc cards for the r4isdhc. Thank you for taking the time to read this post.
