DevHook .51 Help

Installed DevHook .51 with the installer, but when I try to boot it up, it loads like .45 did, but when I try to emulate any version firmware (2.71, 2.80, 2.82, 3.01, 3.02), it reboots, shows the white PSP screen, then shuts off. Is there something I am doing wrong? I am trying to play MGS Portable Ops. I tried running off the UMD, then I tried running the ISO (I own the game, got it for X-mas, I am just trying to play the damn thing). Need some help please.

Iso...we can't help. now, about the Devhook, I am not very good in DH now, what you could do, is check if you have the 3.02 files in your DH :)

only f0 what now?

I got it working. The installer would not create the flash1 folder in each respective firmware folder in DevHook. I just created the f1 folder in each firmware folder and it installed everything like it should. Thanks for the help.
