Bulky PSP and HomeBrewed Games

Hi there well i've tried some HomeBrewed Games on My Bulky System the first psp version and the games do not wanna load i always get a error saying game can not load Do these games only work on The Slim Version?

Give more information like what version is your psp and what games,just be a litttle more specific.Also they do not just work on slim version,they work on any psp.They game coulnd't started because probably your psp version.

The slim can't play 1.50 homebrew. Well they JUST found a way to make it so you can, but you are probably trying to play 1.50 homebrew.

My System Software is 3.90 and i've tried Super Mini Mario and One of the Dragon Ball Z Games from the site they both faild to Load
Do I Need to downgrade my psp?

They are homebrew games, so an official firmware psp can't run them. You need to be on CFW.

i found your Firmeware but it wont let me downgrade am i stuck with the Offical Version? i wish i foun d this site first before i found the offical Update
