I just bought a DSTWO. I installed EOS to the mSD and added a rom. The card loaded fine, and then the rom loaded. After playing around with it, I wanted to add my .sav, so I pressed the HOME button on my 3DS (not wanting to try ejecting the mSD while it was in use). It sat at the black screen for way longer than I'm used to, so I hard reset the 3DS. Afterward, I could not even boot up to EOS. On the 3DS home screen, it shows ALEX RIDER, but when I select it, it just shows 2 black screens, with no error. I tried reformatting the mSD, as well as reseating both the mSD and DSTWO. Also, it will not boot in another 3DS, and I don't have access to a DS/Lite/DSi. Also, I tried the firmware update, just to be sure, and still nothing on either screen. Is this a dead cart, or am I doing something wrong? Or is this likely something that needs an older DS model to fix?
