Yes, very useful feature indeed. Some notes about this: according to my tests, the way the CPU speed option works right now is that you MUST boot the game with the new CPU speed in order for it to have any effect.

For example: if I boot Flatout Head On at 333 mhz it will run with slowdowns; but if you pause the game, increase the CPU speed to 666 mhz and unpause it, it will still have the slowdowns; I would have to REBOOT the game with the new CPU speed and then it will work ok. Using savestates keeps the CPU speed you used when the game booted and you saved it.

AFAIK the cheats are activated AFTER the game is loaded, so based on what I said above, if this feature gets implemented, the speed override cheat command would have to be read BEFORE the game boots, or allow PPSSPP to have on the fly cpu clock speed changes.

Interesting, I think that would be the ideal implementation (like a dynamic CPU clock speed range according to the game needs?), but again the "change the CPU speed before booting the game" behavior needs a change.

This is a video for Flatout Head On (thanks to UnlimateDDDDDDDD) with the 60 FPS patch. If you pause the video around 0:05 you see the guy used 0 (auto, 333mhz?) as CPU clock speed, he obviously didn't read my notes for the cheat and that's why it has those slowdowns: at some points it runs as low as 33FPS.

List of games mentioned in this thread where you MUST increase the CPU clock speed in order to mantain stable 60FPS with/without patches:
Outrun 2006(?), Assassin's Creed Bloodlines, Sword Art Online, GTA LCS, GTA VCS, FlatOut Head On, and more... : 60FPS master list, Mar. 2017 ; Reddit /u/Kabuto_Kun : Unlock FPS in PSP games ("easy method") : Permanently patch a PSP game with CW cheats.
