ARK-4 CFW
ARK-4 CFW
ARK-4 is a modern, actively maintained custom firmware for the PlayStation Portable. It is the spiritual successor to the older PRO and ME projects, rebuilt with cleaner code and ongoing community support. For most people setting up a PSP today, ARK-4 is the recommended choice.
What it offers
- Broad compatibility across every PSP model, including the Go and the Street (E1000).
- Plugin support through a familiar configuration file, so you can add cheats, frame counters, and other enhancements.
- ISO and homebrew loading for your own legally owned game backups and community software.
- Active development, meaning bugs get fixed and new features arrive over time.
How it fits the install
ARK-4 acts as the CFW installer in step two of the standard process. You launch it from the homebrew menu after updating to 6.61, and it boots your console into custom firmware. On its own this gives you a live CFW that lasts until the next reboot.
Pairing with Infinity
To make ARK-4 load automatically every time you power on, combine it with 6.61 Infinity. Infinity hooks the boot process so the CFW survives a full shutdown, giving you a permanent setup.
If you are choosing between projects, ARK-4 and 6.61 PRO are functionally similar for everyday use; ARK-4 simply has the more current maintenance and feature set.
