How to achieve perfect audio/video sync (Retroarch android)

[RaduNastase]

Flycast works really well in Retroarch android. Everything is full speed and virtually zero graphical glitches on the games i play, Atomiswave, DC or Naomi (Capcom vs Snk 1 and 2, Marvel VS Capcom 2, Guilty Gear X, XX, Street Fighter 3 upper, Project Justice).

One thing though, is that i can not achieve PERFECT audio and video smoothness. With the Flycast Core settings: Threaded Rendering ON, Synchronous Rendering ON and General Retroarch settings: Audio Sync ON, i get perfect audio and "almost" perfect video, with very slight stutter when scrolling, unnoticeable in gameplay. If i disable Audio Sync in Retroarch, i get perfect Video scrolling, but the audio has a lot of clicks and slight distorsions.

Any way to have both perfect audio and video?

I dont think its possible to get full speed on libretro-flycast in demanding games such as the first stage in Sonic Adventure 2 (where he skates down the hill in san fransisco).

I get the same issues with the same settings on the XU4 and even the more powerfull N2.

I guess for this reason most retro OS's include the standalone version of reicast because that one is capable of achieving (near) fullspeed.

You should try the flycast WinCE core on android. It has some optimizations of the dynarec that may help non-WinCE games as well.

Can the normal (august) flycast core and the fllycastWinCE core, coexist? I'd love to try the new core, but I'd like to keep the normal core as well, as i managed to get almost perfect sync with a lot if trial and error. I will explain "how" in an upcoming post for anyone interested.

Yes, you can have both cores installed and choose which one to use when starting a game.
