It can benefit core sync or performance (lowering the cycle rate may affect FMVS). The default value for most emulators is ~1.0. It is highly sensitive, as any slight change may break or fix the game. (Dividing 100 with the entered value is how to find what EE clock speed percentage % the value is setting.

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. Newer ones such as Jak operate differently, where AdvanceClock only works 2 cycles ahead at the end of a branch instruction.<pre> | ||
