Outputblaster is still working very well with Mame, Model 2 emu, Supermodel but nothing with all the Teknoparrot games. In the logs I don't see any output. I can't be sure it's a problem with Teknoparrot, but the probability seem's high. It happened just after a technoparrot update.
Edit: I was wrong on everything, I'm the one broken
I set Teknoparrot in admin mode because it ask for it to play Mario Kart DX, it broke the output!! Lesson learned, sorry for the waste of time.
