RetroArch 1.7.0 for Wii U. Some help would be very much appreciated

Hi guys. Just found out about the RetroArch port for Wii U. I managed to get it working but I’m experiencing some issues. For instance, the RPX version doesn’t work. At all. It just freezes the console. The “regular” version does work but, (and here are my issues) - The Genesis core doesn’t work. - Which core do I use to play arcade games like “The Simpsons Arcade Game” or “X- Men” or “TMNT”. I’ve tried a couple and they either crash the console or boot me back to the HBL. - How do I use Overlays? I don’t even see the option listed…

I guess that would be it. I’d really appreciate it if someone could help me with these issues since, from I could tell. The emulator (SNES at least) runs flawlessly and I LOVE the fact that we can use integer scaling and and pixel perfect emulation at last. Thanks for all the hard work you put into this. I hope you keep getting better and better.

This thread can be closed now. As everything was fixed by installing haxchi instead of launching it trough the web browser exploit.
