Metal Gear Solid: Peace Walker

[cns00]

in this mission i have to collect 5 classified documents. the last document is on the roof and i need to do a jumping roll over a gap to get it

the problem is to do a roll i have to lightly tap the square button and i cant lightly tap on the keyboard ((((

can this mission be completed on ppsspp? is there a way?

i forgot i had to roll in the very beginning of the game in the training part. while running just double press the attack button and it will work eventually
