It helps fix timing issues. It runs the specified functionality each time a selected IOP offset is reached. FastForwardClock and AdvanceClock help fix core sync issues. It is believed that AdvanceClock stalls the IOP for a specified amount of cycles, while FastForwardClock behaves similarly. 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 (on newer emus, only the end of a branch works). Mfifodrain is still unknown, but only works on modern emus such as Jakv2. || --iop-hook=0x0086ac,FastForwardClock | | --iop-hook || {{Variable}} || AdvanceClock<br>FastForwardClock<br>Mfifodrain || style="background:#212d9c; color:#ffffff;|4 Byte hex (offset),string,4 Byte hex (opcode),4 Byte Decimals (advanceclock value) || IOP native hook, Sony uses it on their official release of Red Dead Revolver.
