here is a list of problems and solutions for the ds firecard. If you come accross a problem that isn't listed please let me know in the comments section.
This is the most common problem with the firecard.
Problem: When I try to load the menu, it has an xmenu.dat error.
Solution: get the latest firmware from here: http://www.dsfirelink.com/DFCN/index-2.html
go to the bottom of the page and click the 1.45 link. it should bring up a download page. Save the .rar archive then extract ALL of the files to your firecard. run udisk_eng_1_45.nds Click the a button to update your card. Then your firecard should work when you reboot it.
Problem: When I try to load the menu, it gives me an error that says, "data not align"
Solution: When you first click the firecard icon on the ds menu, immediatly hold start and select. it will bring up a menu that says either quick format, full format, or cancel. Click full format. (be carefull though, it will erase all of the data on your firecard so make a backup on your computer.) The full format should take about an hour and a half. Then repeat the solution for the xmenu.dat error.
Problem: When I updated my card using something other than the firmware from the official firecard website (www.dsfirelink.com) it says error: not format.
Solution: When you first click on the ds firecard button on the ds menu, hold a,b.x.y,L,R,and up on the d-pad simultaneously. It will then either give you the option to quick format it or it will automatically format it. Then repeat the xmenu.dat error solution.
Problem: When I try to load a game, it says "file write error"
Solution: Go to usb mode and delete lastsave.sdb in the DSYSTEM (or DSSYSTEM) it will erase all of your save data though.... but it should fix it.
