Earlier today I thought it'd be cool if me and my girlfriend played Final Fantasy Crystal Chronicles: Echoes of Time together, but when I put the rom on our SD cards, hers worked perfectly fine, but I got an error code -81. We both have DSTT's and firmware 1.17a12. At first I figured it would work if I just copied her rom and firmware over mine, but still, the same error, and hers continued to work. What in the world is going on? If it makes any difference, I have a 4gb SDHC, and she has a 2gb SD.
