Homebrew Developer Dark_Moon, the creator of the kernel add-on for Custom Firmware (CFW) 3.72 HX, has released a kernel add-on for CFW 3.72 HX-1. This application allows users to run the 3.71 kernel on the aforementioned firmware for the PSP.

To make it run on 3.72 HX-1, Dark_Moon patched the original program that comes from Dark AleX. Users should be advised that this add-on utility doesn't work on the newly released 3.72-HX2 though.

If you plan on using this application, be careful since it can potentially brick your Sony PlayStation Portable if you misuse it. All the necessary information can be found inside the readme and by checking the PSP forum link below.
