I need some help to patch FF9 (french)

Do you think it may be due to the patch?
I read that the french and german patch don't work.

If I want to make a backup CD, which specifications are needed? I know for the RAW DAO mode. But what for the Subchannel data?
Do my burner must read, write or both to make a good backup? And do I need a reader that have the same functions?

Many thanks for your answers
