The latest bugfix release appears to be PS3 Cheat Enabler v1.4.1
, but as for learning how to make the cheats you may want to check some of the posts by Skiller
It appears most of the cheat lists used for devices like P3Go
, E3 GoldenFinger
and possibly Code Freak for PS3
are based on them. Some are also uploaded HERE
but you'd probably have to examine how they did them in order to learn.
If I run across any simple guides I will reply back though.
