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

[LunaMoo]

I don't think UMD and PS Store copies of this game really differ in any way, they even share same ID while modified releases usually get new ID.

Either way importing character for new game between different saves is allowed normally in this game and does not have any special protections(which hotswapping in-game would:]), so if it does not work for you, it might be for example due to cheats used since most of the simple cheats made for PSP(and MH games have tons of those) does not have any safety checks and while they might work in some locations, they're actually corrupting the game in others.

Anyway to do what you want while technically supported, you don't have to eject/insert memory stick at all. Simply swap savedata folder you have now with one you want to import the character from by renaming/moving the files, it'll be "memstick\PSP\SAVEDATA\*gameID*"(where "memstick" location differs depending on your platform and user priviledges, on windows for example it would be either inside ppsspp folder if the user has full access to it or in "my documents" otherwise). If you're lazy you might even get away by swapping just the .BIN file inside that folder.
I would just backup that file, copy new one on top of it to import character when game asks for it, then restore the backup when game wants to save that imported character to your old savedata.

It's really nothing complicated, the only reason it might appear more problematic than on real PSP is the fact you're dealing with files and not eject/insert physical objects, but in the end you actually doing less as you can swap just required savedata file instead of whole memorystick.
