1. I downloaded some DS roms and they are in WinRAR. Do I have to use a program to convert these roms into another format in order to run them? 2. Is Moonshell already included in R4, or do I have to download it myselves? 3. I heard that the R4 DS compatibility for homebrew applications was limited but that this has now been fixed with DIDL right? So where can I get DIDL? 4. I downloaded Resident Evil DS and it had a rom size of around 100MB, just wondering if I put it into the microSD will it take up more space since I heard they round it off to file sizes like 8MB, 16MB, 64MB, 128MB etc. If it's like this where can I download a trimmer? 5. What program do I need to convert videos into the correct format to play them on the DS? 6. How much space does a save usually take? THANKS FOR THE HELP!
