Noob having trouble installing ISO

[QuoteUnquote]

Hello,

I am brand new to CFW on the PS#, though I have modded Wii's, PSP's etc.

Yesterday I went from 3.55 OFW to 3.55 CFW to 4.30 Rogero CFW.

Everything seems fine however I cannot get ISO's to work from the internal HDD. The game I am speaking of in particular is Disgaea 4.

The ISO is in the game folder of my HDD(I tried GAMES as well), but it does not show up anywhere on MM or the XMB. I have toyed with this
for hours and googled every subject I thought would be relevant with no help.

Please help me

EDIT: Wanted to add that when I try to run the ISO through MM root directory I get an error saying I need "Cobra USB"

You cannot run ISOs. Only Cobra can. You need the raw files and place them in the GAMEZ folder. Rip your original game in MM and it will automatically put it in the right place.

thanks to give the information
