my idea to ppsspp [this is can be help the players]

[vsub_]

This was requested so many times I stop counting.

There are command lines that kinda do what you want.

Code:

--config: Tell PPSSPP you want to use a different config file than the default. Could possibly be used as a primitive per-game settings system, or used for testing.
Example usage: c:\emulators\ppsspp.exe --config="c:\emulators\games\psp\ff4\ff4.ini"

--controlconfig: Tell PPSSPP you want to use a different config file than the default. Might be useful for someone who wants to have per-game control settings.
Example usage: c:\emulators\ppsspp.exe --config="c:\emulators\games\psp\ff4\ff4-controls.ini"

Start ppsspp,make your settings for the game,close ppsspp,rename the settings file,create a shortcuts with those command lines pointing to the files and the game image and your are done...you have per game settings.

The only drawback is that it only works on windows.
