Is neo 2.2 mod chip good enough - Dad newbie

[longshort]

Charlie

Thank you for your post

Please help me to understand a few things

Will the neo 2.2 work with import back ups?

Is that version of Gameshark out dated and how can you tell what version you are buying?

Based on your experience what mod chip would you suggest that would play import original and dvd backups on a version 4 machine. Is it something that I can install?

Thanks
LS
