Hi, I'm trying to help my friend install the MHX cia on his 9.9 O3DSXL, I have a copy of Sky3DS with Cubic Ninja and Gateway. https://i.imgur.com/DYZgAX6.png From the above flowchart, I see that Ninjhax works. However, I can't seem to find anything that works on 9.9, only 9.2. Anyone can point me to a Custom Firmware that works on 9.9 and will allow me to install cia files? Edit: Darn, didn't see the information about it not working before creating this thread, guess my friend is out of luck.
