Searching for Retroarch on youtube, I came across this mind blowing video
I don’t remember seeing these shaders mentioned anywhere here or on byuu’s forums (and search didn’t turn anything) but Opium2k seems to be a member here with one post.
His original post can be found in the General Gaming/Off-Topic section of a website called Tortuga-Cove where his post only got 1 criminal reply.
I just thought this deserved much much more attention. Both for Opium, (if you are reading this: you are a freaking genius!) and for RetroArch. Those are a fantastic showcase of what RetroArch can do. I remember when Themaister introduced the functionality but I thought it had been nothing more than an experiment.
And just to be clear: I am in no way affiliated with Opium2k, all credits goes to him. If people know how to reach him, make sure he knows his work does not go unappreciated!
EDIT: Here is his twitter, just in case https://twitter.com/opium2k
EDIT2: The project has its own googlecode page with a handy “all-in-one” download: http://code.google.com/p/retro-arch/
