Yes, I have read the sticky that's currently up there. I'm making this thread for clarification. What I own: 1st-gen 3DS. Firmware version: 5.1.0-11u What I want to do: Play DS and 3DS roms. Anything indirectly related to that is a plus, but I don't care about anything else (i.e., integrated facebook support, web browser, youtube, etc.) According to this sticky, it looks like my best card for this is the R4i Gold / R4i DSN. My questions: 1. What's the difference? The chart's listed both as the same, but the two appear to be different products. 2. Does it support my firmware version?
