Hi everyone! I'm new here, great site/forum! Ok, I've got a Nintendo DS Lite for my daughter and one for me along with two DSTT cards. At first everything worked fine, but when I transfered .nds games I've got online (from "reliable" sources), whenever I selected a game in my DS Lite it would freeze at the "Loading" screen. I am using a MacBook with OS 10.5.6 and that is probably the problem. I reformatted the card through the Mac's disk utility as FAT32. Then took the files from the other (untouched and working) DSTT card into the reformatted one and it still freeze. My guess is that the problem is Mac related but I havent been able to find any infos online. I finally remembered an application called Blue Harvest that cleans up the Mac OS X of all transparent and junk files. Now all the .nds games I have are on an external drive which is formatted to FAT32 and whenever I add something to it I use Blue Harvest to clean up the disc. I can transfer my .nds files to my DSTT card (which I also run through Blue Harvest -- just in case) and its working! Well actually all games are working about from two (CARS and CONTRA). These two games froze at the "save data" part and while looking at the DSTT card content through my Mac I can see two alias files of 4kb for both CARS an CONTRA but I can't delete them! Why? Another question, ever since I had to reformat my DSTT card, whenever I run Moonshl on my DS Lite I get a error message that something is probably missing. But I'm still able to watch movies, photos and music through it. Could it become problematic? Finally, is there a section on this forum where I can learn about customization of the Moonshl interface and plug-in? Thanks!
