I was given a DSi NAND dump by someone who does not want to be named. Idecrypted the DSi NAND dump and modified each DSi system app srl that I found so that they could show on the 3DS home menu and converted them to CIA. Three of them did not work at first: DS Download Play, DSi System Settings, and Retail Launcher(Launches the DSi Menu). DS Download Play would not boot no matter what I did to it, so @Apache Thunder sent me his dev DS Download Play srl that worked fine as a CIA. DSi System Settings works if you add the missing files that are in a DSi NAND but are not in the 3DS's TWL NAND into the TWLN. However, if you change the Title ID of System Settings to make it show on the home menu, it will break the modcrypt and won't work. Because of this, I edited the source of Apache Thunder's PictoChat Launcher to make a CTR mode forwarder for DSi System Settings, so that I could boot it from my home menu. To use that forwarder you must have the unmodified DSi System Settings CIA installed as well. Retail Launcher does not work as of now, but @Apache Thunder or maybe even me may find a way to boot it eventually. The DSi Shop boots but cannot connect to the internet. However, DSi Browser boots and can connect.You can browse the internet just fine. The DSi Nintendo Zone also works, and you can use the offline memo option just fine. There are no more DSi NZone hotspots, so I was not able to test if the 3DS could connect to them. DSi Camera works, but cannot view photos taken with the 3DS Camera. You can view the photos that you take with the DSi Camera with the 3DS Camera though. DSi Sound works like how it did on a DSi, and PictoChat and DS Download Play work the same as well. The only DSi System App that I did not include is the 3DS Transfer Tool, because that was not in the DSi NAND dump I received. UPDATE (5/23/2017): @DarkGabbz was able to backup his DSi NAND and give me the EU .app for 3DS System Transfer. I made it into a visible CIA using the same method plus Apache Thunder's modcrypt script. The CIA is in the Google Drive folder but not in the mirror. Make a NAND backup before playing with it!
