Help Please...R4 dummy

Sorry to seem like a dork, but I've downloaded the Roms, and got my R$ and my 2gb SD micro.... but I just don't know how to get it to work. Has anyone got idiot-proof instructions please..... Thanks in advance Steve

Extract the ROMs from the archives with Winrar, put them straight on your MicroSD, install firmware, and then boot up. THere's a tutorial somewhere in Tutorials section on this forum.
