Viewing system temperatures, and manually controlling fan speed.Playing PS2 games through software emulation on non backwards compatible consoles.Backing up game discs onto the hard drive, and playing them without the disc.Systems run newer firmware either through the factory, or through official system updates.Ĭustom firmware allows running homebrew software, allowing the PS3 to do much more than originally intended. The majority of PS3 consoles are running firmware versions newer than 3.55, which doesn't have the same encryption problem. In this version Sony messed up the encryption system which allowed the PS3 hacking community to create custom firmware updates that could be installed, also called custom firmware or CFW. Sony released firmware version 3.55 for the PS3 in late 2010. What is custom firmware, and what it's used forīefore I begin I'd like to provide some background information. Update: I have written another post going into more detail on custom firmware installation using a Teensy on a CECH-2001A PS3 slim. This post describes my experiences during PS3 custom firmware installation on my fat CECHA01 console, and my brother's slim CECH-2101A console.

Installing custom firmware onto my PS3 was one of my goals I mentioned in my project introduction post.
