Having an issue with Retroarch Wii

Retroarch gave me a lot of trouble but never a straight black screen when opening.
There was recently an attack on libretro servers and I don't know if the latest wii build is operational... Try a former pre-packed build like 1.9.0. that You can find here and see if it loads.
If you get the black screen again might be an exception, e.g. it happened to me when connecting a 3rd party classic controller, make sure you try with the wiimote alone. Otherwise let me know.

 

The straight black screen is because the boot.dol doesn't work.

Rename any core to boot.dol and you should be able to load Retroarch just fine.

Sidenote: I'm using 1.9.0 Snes, Nes, Gameboy, Advance, Genesis, Turbografx, NeoGeo Pocket, Doom, NXEngine, with 1.7.5 CPS1, CPS2, Mame2000, and 1.3.6 Mame 2003, NeoGeo and CPS3 cores.

Snes9x2010 is reanamed to boot.dol

 

Are you sure your boot.dol is inside a folder called retroarch and that folder inside the apps folder?

apps -> retroarch -> boot.dol

 

Try deleting config files.

 

Did you try the packed distribution I mentioned? It's faster than trying around.

You can install it in another /apps folder, i.e. retroarch-wii and you do not lose anything for trying, they will appear as different apps in HBC.

I have 2 retroarch installed, one based on 1.2.1 (better compatibility with some cores, like old FBA Neo Geo) and 1.9.0 (one of the latest, for better controller - including NGC - compatibility), plus some standalone cores based on other versions as separate apps.

 

Then it's most likely a cIOS issue. Just try these three debugging steps to rule out any hardware exception (probably you already did):

1) disconnect any controllers other than the wiimote you are using to switch on the wii
2) Are both retroarch-wii and HBC in the SD card? then disconnect any USB hard disk.
3) Switch on the Wii and try to start retroarch.

If it is still giving you a black screen, could you possibly run "syscheck" in your wii and paste your response here, so we can see whether there is some missing/outdated cIOS causing the issue?

If you don't know how to do it, refer to this tutorial:

P.S: Do other apps work well, i.e. usb loaders, etc,?
