Triiforce_MRC on SNEEK/UNEEK
(After reading through the rules, I don't think there should be any issues with this, but if that's not the case I apologize in advance and will take down my link)
I did some searching, and other than some vague instructions on how to get Triiforce to run on SNEEK, I couldn't find anything on using Triiforce_MRC (mod of triiforce that has a system menu-esque GUI).
I took the source code for Triiforce_MRC, made a few modifications (mostly commenting out some sections and changing a variable or two), and got it to work with my UNEEK NAND. If anyone's interested in trying it out, you can download it here:
Put the triiforce folder found under apps in the archive into your apps folder to use it. I've only tested with UNEEK, but I'm pretty sure it should work with SNEEK as well.
There's also a wad to install a forwarder I created. I have no idea if this forwarder will work with SNEEK or not (worst case you can try it and then delete it with ShowMiiWads if needed). If you use the forwarder and try to exit from triiforce_mrc by hitting the home button (while not inside a game), make sure to change the exit method at the bottom of menu to "Reboot to Wii Menu" (and save changes) or else it will code dump. Exiting from a game should just bring you back to the system menu.
Check out the included readme_en.txt for information on getting images to load. It's the readme that came with the unmodified triiforce_mrc, so not all of the information is accurate, bu the image loading is.
If you're not familiar with triiforce_mrc and want to know more about it, this is a great thread to check out:
Let me know if there are any questions and I'll do my best to answer them.
EDIT: If you're using a NAND built from ModMii, you'll need to copy the cert.sys file from the sys folder of a full NAND dump (or get it from somewhere else I suppose) into the sys folder of the ModMii NAND. Without it, you'll get an error when you try to launch games from Triiforce_mrc.
Also, I found out there's some kind of upper limit to the amount of games on the NAND that programs like Triiforce and Gecko can handle. I don't know what the limit is, but when you try to load a game, you end up just getting a black screen forever (this was my experience at least).
