I know that 9.2 is still exploitable with the MSET DS Profile and browser exploits, so I updated the SysNAND on my o3DS from 4.5 to 9.2. Now I want to launch Gateway's Launcher.dat using MSET from SysNAND 9.2 so that I can boot it offline or without an Android device.
They have instructions for setting this up on an n3DS and someone told me that it would also work on an o3DS. As far as I can tell, it doesn't. When I follow Gateway's MSET n3DS instructions and set up using the NVRAM option with the USA MSET file on the SD card, it installs without issue but I get "An error has occurred" when I launch "Nintendo DS Profile." I installed the "bluecardfix.cia" to get the old install method working on 9.2 and ran the Gateway installer from there, which installs without issue but gives the same error when I try to launch it.
I can still launch Gateway's Launcher.dat with the browser but that's really going to annoy me as I don't have consistent access. Gateway's Launcher.dat supports MSET on 9.2 because an n3DS on 9.2 can launch it from MSET, but it doesn't look like they made a working MSET on 9.2 for the o3DS. Is there some kind of alternative I can use?
