Dolphin, the GameCube and Wii emulator - Forums

i used dolphin 3.5 wii speak then i started to use dolphin 4.0.2 
all games workes on older version but in newer i just get
black screen and sometimes black screen with yellow text
fps 0 vps 60 - 100%
the games im trying to play are just dance 2014 and just dance 2015

Anything older than 4.0.2 isn't supported in these forums. Just Dance 2014/2015 requires wiispeak branch, you need a custom build based in current revisions merged with wiispeak branch or a build from Dolphin Ishiiruka, otherwise you'll always get a black screen at boot...

can you give me url

how i can recognize that it is wii speak branch

This isn't the wiispeak branch, but rather the other one that should work:

Well, wiispeak branch is almost dead (it's only accessible from the old Google Code repository). Here's a build I compiled myself that should work. It's veeeeeery old (4.0-206 + wiispeak) but it's still supported and works flawlessly with Just Dance 2014/2015. However, if you want the latest features and speed improvements made to the emulator, it's better to use Ishiiruka...
