For those being still interested in making this port a reality, there is one HUGE thing that should be done.
The most important element to fix is related to this
Bug Report #1241 :
Using the latest DevKitPro installer, I noticed that you cannot be able to compile it, as it is stuck saying that "
gctypes.h" is nowhere to be found, despite being able to see it in this following folder :
<DEVKITPRO DIRECTORY>\libogc\include
This is happening to me on Windows 10 and on WSL with Debian 9.0. Other OSes should act the same way. I checked the Makefile several times, and I'm definitely clueless.
Anyway, it is said that recent DevKitPPC builds have broken several other Wii homebrews, so I have seriously no idea how to fix this mess.
That said, there are still a few issues to fix with this port, and, if we have something too, be able to compile it to WiiU (for better options).
