great post, great effort!
what you should add though, is a README. Something to get new users started. What do i do once i download the files? Do i copy it onto the SD? Then what? How do i switch FW's?
Like for example, holding down the A button only lets me choose Sakura and TP, how do i boot into other Firmwares? How do i access RTS features using the different firmwares? What are the hotkeys?
Of course i know all these things, but i had to figure it out myself. A short and sweet section, call it "QUICK START GUIDE" maybe, and this thread becomes even more awesome. I still don't know how to access RTS in the R4iRTS fw.
