ps2 tool disk backup
 

anyone know how to backup the ps2 ultility disc(1.01) and the gameshark2 disk.

Depends on how you plan to use them. They can be backed up with CDRWin and patched with Universal Patcher or ASA Patcher but they would have to be booted behind a valid original.

What do you want to do? You certainly can't boot them no swap unless you have a MESSIAH type chip.

thank you so much! i just want to backup the gameshark2 disc to boot the ps2 in case the original one damage.

My ps2 setup like:
15000+modchip+DOA2H
boot up ps2 cdrom/dvd:press reset 2 times
boot up ps1 :press reset 3 times

by the way, i am a chinese

If you go to this website ####://www.cdrinfo.com/software/clonecd/index.shtml and click on the software tab, you could download CDCHECK. Then on your PC check the condition of your GS CD. If it reports no read errors and no repeats, then don't worry, yet.
