Re: Uae4arm: Amiga emulator with JIT and DispmanX

Yes i see but i've never been a big fan of retro-arch: the default menu sucks, core are always behind the best standalone ones and no frontend are well adapted for computer emulation. But it's a killer for an all-in-one emulation box... (well I even think that pi can't be perfect due to un-availabi...

Re: An emulator input lag investigation

I take you are using the libretro cores for those emulators, right? It's not clear because you say that you use RetroPie on the Pi (and I don't know or have interest in knowing what backends it uses, which is of great importance). If so, do you mind me taking this post to the libretro forums for dis...

use the best game-oriented distro available on the Pi BY FAR (Lakka) I have never heard of Lakka; what makes it so superior to RetroPie?

No crackling, no drops, nothing wrong really. Then again I am using a physical 50Hz video mode via tvservice.
