gcos 1.5 wont work

[emuhelp13]

i see a video of a guy using gsoc 1.5 on dolphin i think 1.2, and it makes ssbm run perfectly, but when i open gcos 1.5 on dolphin(vs 2.0) it just shows a black screen, nothing there and at the top its like vps 40/60 but no fps and screen black, how do i fix this? and where can i get a versino of dolphin 1.2 or any version that runs ssbm better? thanks, sorry im a super n00b

You really don't need that, just run SSBM in the latest build.
You can download it here.
