The following info ripped from Paradox .nfo file of the game Ridge Racer 5 (for PSX2)! It is only being released in PSX2 CD and it supposed to act as a cracking lesson for all cracking/gaming releasing groups. Paradox introduced cracking in PSX1 scene. Will they make it again on PSX2? Very difficult task indeed. ;)
"..Paradox is ready to take off with another title. This time it is Ridge Racer 5 from NAMCO. After EURASiA brought us the first PS2 Demogame release, we are happy to bring you the first PS2 "Fullgame" release! We are sure this title will not be playable after burning back to a blank CD! So why the hell did we release it? - Simple: This CD will be very important for Hackers and Crackers, to hack the PS2 CD structure, to disassemble the main-exefiles etc..In one sentence: "GET THIS CD TO SIMPLY HACK AROUND!.."
