I got a Phat PSP thats hacked and I wanna update to 5.50 GEN-B so that I can play Disgaea 2 and Persona PSP and also Soul Calibur.Is there any downside to upgrading from 5.00m33 - 6 to 5.55 GEN-B e.g does 1.50 kernal work?

what is your current CFW? GEN D2 is now released. As far as I know, it doesn't have any effect on upgrading from m33 to Gen. So I think it's great. Btw, I play Disgaea 2 and Soul Calibur using 5.00m33  I use the hacked version of the game though 

Hm...if you love Fable, then you will probably love Fable 2.
For RPG, I love The Last Remnant...maybe you should try it too.
And for FPS, Doom 3 is still great for me...
