Anyone had any luck getting Mystical Ninja Starring Goemon to emulate on the N64? It has the same issues that have plagued it in the past where it has extreme stuttering/lag when outdoors due to the sky. Overclocking has not helped at all.
hyperxunda's post above did the trick for me. But all I did was take this line:
enable_deprecated_hid_mitm = u8!0x1
and added it to my existing "atmosphere/config/system_settings.ini" file under the [atmosphere] section.
