Hello folks, new user here. Now I am posting in this subsection because the ad I found listed for flash carts is in fact for a "RD4 SDHC" apparently, at least from what the image shows. I have called and emailed and texted to confirm. However, I wanted to get an opinion from you knowledgeable folks before I got it. Here is the ad: http://orlando.craigslist.org/vgm/3586025471.html So, I would be using this with a DSI XL I just got, the XL is updated to the latest update (no new ones). I want to be able to play DS, GBA, and SNES games. So would this card be able to do it? Also, what would I need to do beyond buying it in order to handle my wants? Would I need to change the firmware? Which firmware should I use? How does one change it? If you guys have an article or something I can read just point me to it and I will get out of your hair!
