best for ps2 is without doubt nero version 5.5.7.x or above, try to stay clear of versions above 5.5.9.0 as there have been several reports of problems with the later versions.
to back up your original game (or a back up of it) do the following
open nero
cancel any window that opens
select your cd writer or dvd writer (depending on what you are backing up
) from the tools menu
from the file menu select new
a window opens, select wizzard
follow the wizzard through to select copy a cd or copy a dvd
if you are running windows xp on ntfs or if the game is LESS than 4gb in total size if on win 98 or fat32 uncheck the box that says fast copy on the fly (you must leave it checked if your game is over 4gb and you are on win 98 or fat 32)
select your recording speed (try to stick below 24x for ps2 cd's and use 1x for dvd's unless you are using top quality branded dvdr media (apple, pioneer, tdk or verbatim)
now depending on how much time you have and what file system you are using (fat 32 or ntfs) select test and burn or just burn (if you need to copy on the fly its best to test and burn, if you are not copying on the fly then just burn)
then hit start (you did remember to put your discs in the reader and writer didnt you
)
when its done, just throw it in your chipped ps2 and away you go
