PPSSPP Crahes with more than 4 Inputs/Key presses

[Drogiri]

Evening guys.

Sorry first of all if this the wrong place to ask such a question, never properly used a forum before.

Essentially i got into playing Monster Hunter Freedom Unite with my friends on a private network and have been trying to set up my PPSSPP to run with keyboard and mouse.

Two hours into playing the game or so, i start getting these weird crashes , no warning messages no nothing , just sent back to the menu screen where you can choose the game you want to play.

I read up that originally the PSP doesn't support more than 3 inputs at a time , so i believe that using the keyboard and doing more than the 3 said inputs that the game just crashes.

I apologise for my lack of understanding of Emulation software , but i hope i can get some help on this issue or at least a confirmation/correction.

Thank you for all the answers upfront.
