I've only ever had fat PSPs, and I have the process of installing homebrew firmware down pat,
but now I have to install CFW on a limited edition Final Fantasy Slim.
I know FW150 can't run on it so what are the basic steps?
Usually, the magic memory stick would install 1.50 FW, and I'd go from there.
I'll find the details myself, just after the basic plot! :)
