More accuracy on PSP emulation?

Or choose to be sad as that's what you're doing already. If you ever try to write your own emu, at least learn more about PSP first as you're confusing it with older and completely different platforms. PSP for one had an operating system, not just a simple bios, it also involved modern encryption, some required keys are still not known so you need real hardware for decrypting aka you can't even write a low lvl emu with similar compatibility yet if ever.

"Cycle accurate" is not easy, modern cpu's are likely forever too slow for that outside of some very old hardware doesn't matter if it's low or high lvl emulation, i9 is as "fast" as i3 for such usecase.

No idea why would you mention integer scale. PPSSPP has many ways to scale via fixed integer values as well, but it doesn't even matter as PSP games doesn't look any worse without it.

Cycle Accurate is a long distance. But High Accurate is beginning. PS4 emulator in progress now is based on High/Cycle Accurate. lol
Obviously, a long years of road.
