Hello i want to know if there is some kind of software i can install with LCFW 6.39 ME-9.1

to allow me to cheat on some PSX game

i don't want to brick my psp and im highly satisfied with LCFW 6.39 ME-9.1

i just want to know if its possible to use TempAR or something similar without bricking my psp

otherwise its okay i can run all the games i want so i don't really care
