Functioning Miiverse applet

Open ariankordi opened this issue 2 weeks ago • 1 comments

I've added the missing functions from nn_olv that Miiverse needs to boot (the "PortalAppParam" methods specific to the app). First commits are borrowed from @jonbarrow's branch.

That lets the app boot without crashing, but I also added two code patches needed for Miiverse clones to work:

  • Bypass the internal allowlist in wave.rpx

This is why the applet will not even attempt to load from non-Nintendo domains, staying stuck on the loading screen. Inkay gets around this by replacing the .nintendo.net entry in the allowlist. But, I was able to find a function responsible for validating this and patched it from Cemu to completely bypass it. Only tested with the USA titles, though. I noticed eShop shared the same function code, so it should work there too, and so will Account Settings if patched manually. I put a note on where to find the function in GamePatches.cpp.

  • Pass CA cert validation

Otherwise, the browser shows a generic error message. I added the same patch done by PretendoNetwork/Meowth as well, applied only if SSL verification is off. (Notably, *.pretendo.cc or any other Cloudflare domain will work without this, as they use a GTS CA that's already trusted on the Wii U.)

Now, Miiverse successfully loads on Pretendo without nn_olv.rpl or any other patching :)

Feel free to suggest feedback for any part of this, or if we should split the patches out of Cemu or anything like that. Thanks.

🙏 I've been wanting to take a stab at this again at some point but never found the time to sit back down with it, thank you for finishing up my experiment 🙌

Using GamePatches based on the network config is a sensible approach for this. Great contribution, thank you!
