I have a DS Lite with a R4 card, works fine, no issues. I was planning on getting a 3DS XL in a few weeks and I figured my R4 wouldn't work on it. I was trying to decide on a new R4 card to get that would work on the 3DS XL and my DS Lite. I can't seem to figure out what the difference between the R4i Gold and R4i SDHC is. Any advice or opinions would be greatly appreciated. Thanks!
