this is just another guide to launching elf's on a ps2. i have only tried this with my own and its a totally unmodified fat ps2. what you will need: ps2 (fat is the only guarantee) AR MAX (must have media player) memory stick (fat format, i used the 1 that came with AR MAX) cdloader.elf some type of elf loader cogswap.elf load up AR MAX and proceed to the media player once the media player has loaded tell it to "play" cdloader.elf after a few seconds it will say swap discs. this is where i took my homemade slide card and opened the tray and swaped to my also homemade elf loader disc. open up cogswap.elf (or whatever elf file you wanted) that simple. pictures coming soon.
