Hi, everyone I am not new to emulation or mods But I am when it comes to owning a Nintendo DS I own a new Dsi XL and wondering if this Supercard is the card to get ? Obviously no 3DS games needed or firmware that supports that system or games because I dont have a 3DS I don't want to use the Supercard for the SNES or GBA emulators or media players or anything else I ONLY want to play NDS USA backups I want to know if this is the card for me ? And I guess my real question is --- after the firmware is on the micro SD card and inside the supercard cartridge does it make new firmware on the actual unit itself ? Can I take the supercard out of my DSi XL and still play original USA DS or DSi cartridges ? I know my question may be lame but I'm asking because it's more about a child's gameplay not my own Thanks for the help appreciate it a lot ! p.s. Is the firware easy to install ? yes I have read the wiki Thanks again !
