Is it at all possible for you to rent a 5.3.2 game instead of buying one? Later today I'm going to rent a copy of Smash so that I can test Loadiine and make a video tutorial if everything goes according to plan.
Which reminds me
@EclipseSin could average users potentially just skip all of the hosting and use your site eclipsesin.ddns.net to launch the exploit? Basically put files on SD card-->Block Nintendo update servers-->Launch your site-->Run Loadiine Kernel-->Restart browser-->Launch Loadiine-->Launch Mii Maker-->Pick game-->Launch Smash
I'll find out when I rent the game anyway but I wanted to see about making this as noob friendly as possible and it would be great to just skip hosting everything themselves (because there's also no clear guide on how to do that). Obviously I'd give you credit for the site.
