The game's requested CPU frequency wasn't stored anywhere, only the effective CoreTiming clock. So a state saved with a locked clock kept that speed when loaded with the lock off, and turning the lock off in-game left the CPU at the locked speed until the game set its clock again (most only do at boot). Changing the lock in-game didn't take effect either, until a reboot or a state load. Now RealcpuFreq is tracked and saved next to the PLL and bus, the setters record the game's request even under a lock, and one function applies either the lock or the game's clocks. It runs at init, on state load, and at vblank whenever the setting has changed. Older states guess the game's clock from the saved effective one, capped at the game's PLL.
