Memory Stick hotswap savedata import possible? [Monster Hunter Freedom Unite]

As for the cheats affecting savedata, unfortunately yes, in fact Patapon 3 you mentioned has a whole infamous case of what some people called "infection" where not only your savedata can be corrupted, but also savedata of people playing with you through adhoc:]. All caused by a poorly made cheat constantly writing memory at same location to change chest rewards, which ends up offsetting some important pointers a few moments later when it's trying to save them.

Most of such problems happen because PSP doesn't have much ram and in many games simply has to move stuff in memory quite often. Unfortunately PSP cheating scene on the west was kind of meh, most people involved never even tried to learn so there's a lot of potentially unsafe cheats out there. In worst case scenario something get's successfully saved which game was not programmed to see which might lead to crashes, permanently glitched items and other weirdness.
Fortunately it's not that common, typically if cheat breaks stuff it can be fixed by restarting/reloading the game with those cheats disabled.

Sometimes unsafe cheats might also cause instant crash on boot even while working in-game, so it's worth mentioning that PPSSPP also has game/info screen accessible via triangle, right mouse button or touching for few seconds game icon on the list where cheat menu can be safely accessed before launching the game:3.
