Here’s a quick list of what you can do so far on a hacked PS4 4.05, in no specific order:
Linux on PS4
Linux on the PS4 was a thing on firmware 1.76 (formerly the only hacked firmware), and that has been ported to firmware 4.05. Multiple distributions are circulating on scene sites, and, although the port has its limitations, it’s always cool to run Linux on yet one more device.
In theory we should be able to start creating homebrew for the PS4, and release them as pkg files (just like official games). So far though, the scene has been a bit slow on that aspect (most “homebrew” code released so far has been binary payloads for the exploit). In theory all you need to get started is a 4.05 compatible PS4 SDK, but maybe what the scene needs is a good tutorial.
Did I miss any cool feature of hacked PS4s? Please let me know in the comments!
