Update from ARK-4#

If you are already on ARK-4, updating to ARK-5 does not require a full reinstall. You download the update file, run it on the PSP, and it handles the rest.

PS Vita users must update to Adrenaline-8 before proceeding.

Steps#

1. Connect your PSP to a computer

Connect your PSP via USB or remove the memory card and use a card reader.

2. Copy the update file to the memory stick

Download the ARK-5 UPDATE file from the FasterARK releases page↗. Copy the UPDATE folder to /PSP/GAME/ on your memory stick.

3. Launch ARK Update

Safely disconnect the PSP or memory card from the computer. On your PSP, go to the Game tab in the XMB. You should see ARK Update listed there. Launch it and wait for it to complete. The PSP will restart back to the XMB automatically.

The updater may say you are downgrading. This is expected — the version numbers were changed during development. It is not a problem.

4. Clean up and verify

Once it completes, press Square to delete the updater. Then press Select and confirm the CFW shows ARK-5.
