Hello. My nephew has an R4DS, but I noticed it says SDHC. I dunno what that means, but I do notice that the firmwares I've used and YSMenu for my R4DS card (which isn't SDHC) doesn't work on his. I do have a firmware that works on his currently, but it doesn't seem to run Mario & Luigi: Bowser's Inside Story, which is a game he plays often. I'm wondering if you guys know of a firmware that does run this game on an R4 SDHC card? edit: Is this what works for it and will run the game? - http://www.ndslr4.com/soft/33-en.htm Edit2: The one from that link works, as in, it's supposed to work. The only odd thing is that it makes the DS light REALLY dark, and doesn't run the game either. I mean it does, but it freezes up at the save screen.
