If you already have firmware 1.5, follow these instructions:
1. Download UMD Emulator from here: http://www.psp-hacks.com/file/92 2. Extract the contents to your memory stick. It should have these folders: ISO, UMDEMULATOR, PSP\GAME\UMDEMULATOR, PSP\GAME\UMDEMULATOR%
3. Put your ISO (image file) into the ISO folder.
4. On your PSP insert a UMD and go to GAME-->Memory Stick and select UMD Emulator select direct load, scroll down to your ISO and press X.
Note: Which Need for Speed game are you trying to play, different ISOs require different methods.
Go to Settings, then System Settings and then System Info on your PSP. It will then display your MAC Address, Nickname, and firmware version.
For Need for speed Most wanted you can use the method I explained in my other post. If that doesn't work, you can use fastloader (download from here:http://www.psp-hacks.com/file/90 )
