i have a new ps2 case top which allows me to load games through the top, like a dreamcast, rather than using the cd tray. by doing this, the ps2 will never know that the tray opened up allowing me to bypass the copy protection.
how to play backups ...
- open lid and insert either the DVD boot disc, or the CD boot disc (depending)
- slip the black cog back on top of the spindle
- power up
- when the disc stops spinning, swap to your burned game
- press X and you're done
