Im having trouble upgrading

Ive been away for awhile and im currently using devhook 0.51.I had outrun 2006 running on it before but now everytime i load outrun my screen goes blank.I was gonna upgrade to devhook 0.52 but someone said it might brick your psp.Then i saw dark_alex release but im confused on how to use it.All i see is updates and i dont know what version to download so i have to start from the beginning and put in all the updates or what??.I really wanna play PSX 1 games and get my psp iso's workin again.I just got a wireless router and i wanted to play outrun online but the game wont load now.Someone please tell me how do i get started with dark alex releases.

Are you on 1.50?

If you are, I would recommend updating to 3.03 OE-A (then OE-B). Look to my sig on help for the installation.
