Can't stand them 12 year old yanks on youtube? Me neither! no pics, no death metal soundtrack, just me and my irresistible charm to guide you through the quagmire of the world of a few DS carts.
I am using Windows Vista, if you aren't then you may have a slight variation on the options that you are given.
If at all possible, use a "Proper" card reader, and not the one that comes supplied with your flashcart.
The Acekard2 and the DSTT I have given links to, do not come supplied with a USB card reader, dealextreme do have a version with one on their site.
Moonshell is an application that allows you to play your mp3 music files, look at photo's/e-books, and watch videos. some carts have it inbuilt, most require you to add it onto the micro SD card. It is optional to do this part of the process.
Please do not ask for links to illegal downloads or discuss downloading games in this thread. Any reference to questions regarding copyrighted material will be reported to the moderators.
If you have a DSi, these cards will not work on it. You need an "i" variant. PM me for links to these cards.
