Messed up Control Mapping - How to Fix?

[ZeroX4]

i dont know how on phones or anything else then windows bu probably the same

you go to
PPSSPP\memstick\PSP\SYSTEM

and then u need to find game ID file with setting
like for example this is only one i have from retro city rampage named
NPUH10199_ppsspp.ini

and either you open it and edit where on very end are controls and you just want to set pause to this

[ControlMapping]
Up = 1-19
Down = 1-20
Left = 1-21
Right = 1-22
Circle = 1-52
Cross = 1-54
Square = 1-29
Triangle = 1-47
Start = 1-62
Select = 1-50
L = 1-45,20-102
R = 1-51
An.Up = 1-37
An.Down = 1-39
An.Left = 1-38
An.Right = 1-40
RapidFire = 1-59
Unthrottle = 1-61
SpeedToggle = 1-68
Pause = 1-67,1-111
DevMenu = 1-73

which makes escape and backspace pause key

or delete whole file

but does not escape is the universal pause key?

or you're not on windows well good luck
