Apparently its for booting PSX games on a PS2, and its called the PS2 Independance hack
Heres some info:

I dont know how but apparently by putting an exploit into your ps2 memcard's System Configuration save it allows you to boot backup/import PSX games
At least................ thats what I understand
I still dont understand this fully and and not sure how to use it.
One person actually had the save itself to download onto your ps2memcard using link software, eliminationg the need to burn that cd.
But ATM this is all the info I can find.
Anyone got any other info?
