I have 1.50 version on my psp can i now put games on my psp?

Can anyone help me im new to all this ive downgraded to 1.50 from 3.03 but the network config backup wont load it just says some number game cant be started.what can i do?
and do i need network config to play games and stuff?
can i now put games from my comp on my psp now i have 1.50 or do i need to upgrade to 3.03 oe or something like that?

thanx in advance

You can put games on 1.50 yes. However, i strongly suggest upgrading to at least 3.03 oe-c. You can find a winstaller HERE All you have to do is connect your psp to your computer start up the winstaller and it installs everything on your psp itself. Once thats done just cycle to game memory stick and click update to 3.03 oe-c. Simple, and will make your life easier when your trying to play homebrew on your psp.

thanx
but do i still need to get the network config backup to work or does it not matter as long as i dont want to use the internet on my psp?

if u get a custom firm ware (3.03 oe-c is the best) u wont need to do any of that. once u get it u just get proper emulaters then put them in the game folder on ur mem card. then get roms and put them in the emulators

thanx already upgraded to 3.03 oe_c

if u want 2 play psx (ps1 game) put the eboots in the game folder and homebrew in the game150 folder (if dont have make 1)
