Hi guys,
after had struggled a bit with Parallel and N64 I was able to have a good emulation on my Rock64 board. Basically if you leave everything in auto Lakka selects the worst options… 
So the key is lowering the resolution to 360x240 and using Glide64 as GFX plugin. With this setup the emulation is fluid a 30fps and the audio is fine. Even if I like this resolution because it is a bit blurry it would be better if I could apply a scalines shader. So far I saw the best in performance is crt-nes-mini however when I use this shader the graphic is fine and fps as well but the audio isn’t. The audio is completely desynchronized and laggy.
I am trying to figure out how using a shader and having audio without lag, have you any suggestions that I could try?
Thanks in advance,
Daniel
