Noob in need for some urgent help

[FNS]

Hi, I just bought a original psjailbreak last night for my 60GB US Fat PS3. I backup 3 games: Ninja Gaiden, Dante's Inferno, Uncharted 2 Among Thieves to my usb ext harddisk. But I can only play Ninja Gaiden. When I try to play Dante's Inferno and Uncharted 2 Among Thieves. It's show a error asking me to insert game disc to play. Did I miss any step? Or do I need to uninstall anything from my PS3? Really deeply appreciate any helps. Thanks in advance.

There must be an original game disc in your PS3 when launching a game, no matter which one.

Some games need a disk some games don't its a bit of trial and error also make sure your using the newest hex codes for your board that support peek n poke and backups with no disk http://www.ps3news.com/forums/ps3-ha...es-113434.html also some work from external some don't check the Ps Jailbreak compatibility list at the top of the page.

I found out why already. Cos I didn't delete the game data which I did update before I use PSJailbreak. Now most of my games can except Darksiders and Uncharted 2 Among Thieves.
