This is a bug in retroarch / rcheevos, not in PPSSPP. I think it's just that retroarch doesn't know that PSP games can be chd yet, and thus falls back to just hashing the first 64MB which will be wrong.

@Jamiras I think we talked about this once, maybe in the context of CSOs?

[Jamiras]

Yea. rcheevos was updated to allow for that on 7 October, and that, and that was merged into RetroArch on 2 Nov via libretro/RetroArch#15859, so it should work in any nightly after 2 Nov. There hasn't been an official release yet since then.

Alright, I'll close this as fixed then since it's been fixed in code, just not in an official release yet.
