Backup GTA3 from DVD to CDR

[Tortilla]

\ Hi this is my first post.

I´ve already read a lot of threads about this theme but there was nothing useful. I have bought the GTA3 DVD (Pal) and I want to make a backup on a CDR74 / CDR80. I don´t know wich files have to be left away and wich ones are needed to play the backup with a neo modchip.
I have no DVD burner and I´m not going to buy one. I´m not able to get the "kal-gta3.bin" so I would like to make the copy by myself. Hints like "type DVD rip into the search function" don´t help me much. Most of the tutorials are much too general. Please describe step by step what I have to do to backup my GTA3 DVD correctly.
thx Tortilla
