So I've been attempting to do some research; however, I'm not very familiar with DS or hacking Nintendo systems so not a lot is resognating. So I want to get a 3DS or 3DS Xl and here are the questions/concerns I have. Can I hack the system to.... download and play games for the SNES/N64/NES that are available in the market place (like on the WII) put emulators and run them on the device download and play 3DS/DS games on the system I've read about needing a special SD card, I'm also wondering if there is a way to just purchase an SD card and load the firmware on myself? And my final question would be assuming you can do all these things above, is the 3DS XL actually worth investing in over the 3DS? Thanks for the help guys, you'd really make my decision on whether or not to get a 3DS easier.
