Are you using the newer Homebrew Loader Smealum released over Twitter? That should fix a lot of stability issues with running the homebrew itself. GameYob runs just fine for me every time. 3DScraft needs an update to work properly with the new exploits.GameYOB and 3DScraft are buggy and some other old applications from 2014. I have same issue with GameYOB
the first time works but the next time not more.
