Liquidzigong has released his own custom firmware for PSP-2000 TA088v3 (2000v3) & PSP-3000 models. Really it’s more an add-on as the majority of files that make up this CFW are from 5.03 GEN-C. That said, installation is like this:

  1. Install ChickHEN (or MHUSpeed);
  2. Install Custom Firmware 5.03 GEN-C;
  3. Extract the Prometheus 5.03 files to ms0:/PSP/GAME;
  4. Start the installer; Follow the on-screen instructions (press X to install).

Now you can run all the latest and greatest 6.20-required titles without the tedious patching.
