Asking for a friend

[Serpent]

Hi!

My friend has an xbox which he is planning to get modded.

The Evo 2.5 mod chip was recommended. Is it any good? I have a Ps2 and I told him that (poor analogy) he needs something like the Messiah2 for the ps2: you pop in the backup and it plays.

Question# 2: How do you make backups of xbox games? For ps2, I can just make a copy on dvd-r and it works. What is the procedure for the xbox?

TIA!!
