Yes, I know. I even suggested a solution, which is the ffmpeg core of libretro.
I would also like to mention that Anarchy Arcade is essentially a bootstrap that does not run the emulator within the game, but directly calls the emulator itself. So it is different from the VR environment that calls librerto API, such as TU, NRAN, and EmuVR.
The summary is that AA is a bootstrap launcher, NRAN and EmuVR are libretro front-end, and TU is an online game that uses the libretro API.
