Hey Arya.... Not sure if this is exactly what you're looking for, but the site below has a complete step by step tutorial on how to watch movies on the NDS / 3DS / DSi and also what software can be used for converting the original movie file to the DPG format. From the looks of it the software is free for windows... and of course, moonshell is also free. I hope it helps: h t t p ://www.r43ds.org /pages/Movies-On-Nintendo-3DS.html PS: I can't seem to post any links, which is fine, so you'll have to copy the address above. I just put spaces between the h t t p that you'll have to get rid of. Again, hope it helps!
