Another interesting case is GTA SA's lack of need for auto flush on it, and being natively performant. Additionally, its VU0 timing is much better than Jakv2's, making it one of the best emulators on the PS4. || 0.1 || '''Rogue v1 and v2, Arc the Lad, Star Wars Jedi Starfighter''' | ||

FastForwardClock and AdvanceClock help fix core sync issues, but can be used as a speedhack. It is believed that AdvanceClock stalls the EE for a specified amount of cycles, while FastForwardClock behaves similarly. They are commonly used on the offset directly succeeding an affected CTC2 instruction. For a mysterious reason, some offsets are ignored by AdvanceClock - it could be that this function only works on instructions 2 cycles ahead of a branch, likely specifically designed to work at both the start or end of a branch. However, this is only the case for old emulators like King Of Fighters 2000 and War Of The Monsters.
