Then you have a serious problem on two fronts :

1/
Patching is a hit and missi affair. You might find the right patches at megagames.com but for newer games you won't for some time and they'll be on DVD anyway.

2/
GTA3, for example, doesn't have any patches other than to fix the problem of getting it working in the first place. So any subchannel data will not be carried forward on your kit.

To save yourself a long hard time with patches, do get a CloneCD compatible burner for RAW-DAO+96 on both read and write.
