help with installing games and a question

duz 1.5 required games work with 1.51 psp? and no games work on the psp...it either sayz the file is corupted so it wont start or it sayz "the game could not be started (80020130)". same thing happens to my friends 2.0 with 2.0 games...when installing smash pack i even extract to the root X:\ but it extracts, i see it in the stick wen i check the psp but it never runs..what should i do?

FOR THE LAST F!@#IN TIME HOMEBREW DOES NOT RUN ON 1.51,1.52,2.0,OR 2.50!!!!!! !@#%^%#$@&&^%#%#

but i was confused cuz the smash gpsp i downloaded for my friend said it was for version 2.0 calm down...bully

... sorry i just lost conterol people said i have ADHD but i dont see what theyre are talk- HEY LOOK A TREE

WHERE!??

well since u have 1.51 I suggest u upgrade to 2.0 and use the downgrader for 2.0 to downgrade to 1.5.Very great to use.
Since it only supports to 1.5 then that would be the best option.

And I can probably see that your going to ask where to downgrade it well
you can upgrade here:
