ok it is not a news anymore. It have been in development since a years or so and have been released 2 months ago. Still, i didn't saw any threads about it so. Free MC boot is a homebrew application that give to any ps2 models pal /ntsc , fat and slim. The ability to run illegal homebrews with no needs of modchip or it cousin, the ''independance exploit''. So, basically it act like a mini app installed in the ps2 memory card that redirect while booting to any homebrews desired. This little thing is pretty useful in case of dead laser and works plug an play with any ps2.
You can get the software here and its the place where all is involved :
