• cores can be updated from retroarch by selecting "Online Updater" --> "Core updater". only rpx cores are available from the core updater. keep in mind that one the WIIU, loading a core will also load the retroarch version it was compiled with. this means that to update retroarch , you just need to update all the cores you are using. downloading the full buildbot package is a lot faster than downloading the individual cores, so use that instead for a full update.
• databases and menu assets aren't included in the buildbot package, those can be downloaded from retroarch by selecting "Online Updater" --> "Update Databases" and "Update Assets" respectively. assets and databases are rarely updated, meaning that you generally only need to do this once with a fresh install.

about the buildbot

• builds from the nighly folder are automated. while you are welcome to use them, their main purpose is to be used internally for testing.
• if you download a build that doesn't work, just roll back to an earlier one.
• some of the cores in the package don't work yet.
• the buildbot generates new builds all the time, that doesn't necessarily mean that the WiiU port has been updated. you can check the commit history on github to see if there have been any relevant changes since the last build. commits relating to the WiiU port will be marked as such.
• old builds are also periodically deleted so it is recommended to keep a backup of the last working build just in case.

troubleshooting

• config is saved in retroarch/retroarch.cfg. if you encounter problems (like missing sound or input), try deleting the file to start with a fresh config.
• if you can't load some specific content, you can find out if it is compatible or not by testing it on the the desktop version of retroarch.

not yet implemented

• content scanning.
• network updater / netplay.
• video shaders.
• overlays.
• alternative menu drivers (like XMB).
• ...

known issues

• loading content multiple times in a single session can cause a crash with some cores.

Thank you so much for working on this

 

I LOVE YOU.

 

Tried a few games and all play fine apart from Mario kart which crashes a few seconds after a race starts. It's great to finally have a snes emu can't wait to see this improve in the future. Thanks for all the hard work on this.

 

Mabye because I turned vsync off let me try it again as I know my Mario kart rom is fine as been using it on my Android snes emu.

 

I don't know then tried it 4 times and crashes at start of race every time.

 

God I cant wait till we get cold boot emuNAND and retroarch on our home menu! =]

 

Tried another download of the rom and got round one lap then the same thing happened. Tried again and this time even though I was on the track lacitu kept picking me up like I was out of bounds yet I was on the track. Then it crashed again.

 

Snes9x 2010? That's before 1.52, which was released in 2011, unless of course, this has the core merged in it? I'll ask the OP, @aliaspider Does this core have Blarrg's S-SMP in it (for better sound)? Or will the 1.52 and on be ported over in the near future?

A good test would be Earthworm Jim 2, that relies on audio streaming and timing to get right.

Oh man, I can't believe this is happening already, I love it Gonna test later


And thank you for your guys' hard work
