Alright, so I bought the SD Media Launcher and have had no issues running SNES emulators & roms. But i'm trying to get GCoS to run. But everytime I load it up I just get a black screen. Absolutly nothing happends, so i restart my cube and try again. same thing. I've tried re-downloading the .dol files. i've even tried diffrent versions like 1.3 & 1.4. but same thing every time. Am i missing something here? am I doing something wrong? Someone with way more experience in this pleeease help. Thanks!
You could try Swiss: http://code.google.com/p/swiss-gc/ It does the same as GCOS + more and development is still active. GCOS hasn't been updated in years.
