Edit: Nevermind, I got it.
Alright, I'm...confused. This guide says that if I want to install Firmware 3.40 OE-A on my downgraded PSP, I need to use IRShell. However, to install IRShell, I apparently need to "Copy /IRSHELL folder to your ms." This folder is 52MB in size. So...what am I doing, exactly?
Essentially, I'm requesting an in-depth guide to installing Firmware 3.40 OE-A on a system that has only a 32MB memory card. Can anyone help?
