Download link is dead...
Here are some more mirrors to v1.4 also for anyone that needs it:
Also version 1.4.1 is available which is a bugfix update:
Download: PS3 Cheat Enabler v1.4.1
There was an error in the v1.4 release. Version 1.4.1 has a fix for this bug. The bug was a problem with pkg creation that went unnoticed in testing. Apparently I need some new testers, because it was a pretty big bug.
Hehe, sometimes I use MultiUpload to upload to the mirrors and post those instead of the MultiUpload link in case it's Sony taking them down... hopefully it's not in this case but better safe than sorry.
