Homebrew and custom firmware (CFW)
Homebrew refers to games, apps, and utilities produced by hobbyists for proprietary video game consoles which are not intended to be user-programmable. These homebrew apps can include save editing tools, emulators, cheats, and more.
Custom firmware (often abbreviated as "CFW") enables you to use more advanced hacks that homebrew alone can't do. For example, installing games, apps, or game modifications. CFW is similar to "administrator access" on a computer: it allows you to do anything that the device is physically capable of doing, rather than being limited by whatever the manufacturer allows you to do.
