Audio output stuttering

[Fautenic]

I’m developing a LibRetro-compatible core for my F8 Emulator system:

FautenicOfficial/f8emu-libretro

However, for some reason the audio is extremely stuttery. Even using audio batch callbacks doesn’t help.

I currently have the audio sample rate set at 48000Hz, the video mode set to NTSC, and I output 800 frames of audio each frame.

Here is a test ROM you can use to test the audio if you wish:

test-v2.f8

[EDIT]

Apparently it was an issue with the emulation, I forgot to &= a thing. Should work now.
