I'm looking to buy 2 flashcarts and I was looking at the R4DS and Acecart. I'm looking for cheap ones so that is why I chose these two but I'm having trouble deciding which to get. I hear people saying it is hard to find a legit R4 and the Acecart has some sort of proprietary file system but it supports SDHC cards. Can anyone give me an opinion on which to get or if there is a better flashcart out there?
