@Vika23 You cannot adjust clock rate on netemu. Also, that PS4 fix is sort of ignoring the underlying issue of timing handling. Luckily, $ony has a config command that handles this timing issue on netemu. I just ported over Rayman 3's config:
Largo Winch: Empire Under Threat (SLES-50841, SLES-51093)
Code:
3D 00 00 00 57 44 00 00 12 00 00 00 0E 00 00 00
00 00 00 04 00 00 00 00 02 00 04 00 00 00 00 00
AE B3 4E 5D 20 02 00 00 46 02 00 00 03 00 06 00
1C 6E 11 10 F8 6F 11 10 BC 70 11 10 88 74 11 10
C4 74 11 10 58 75 11 10
Tested the very first scene on SLES-50841. May have additional problems later. SLES-51093 is untested.
