Japanese 1.0 PSP

I Have one Japanese PSP, firmware version 1.0.
I'm new in PSP stuff, I'm from Brazil. What's the best thing to do with it? (Like Firmware upgrade, programs to run ISO games)
Than k you very much.
PS. Sorry for the English

for you the best thing to do would be to upgarde to 1.50 and ask elsewhere about ISOs, as its against the rules here

update to 1.5
Can be found here http://www.psp-hacks.com/file/4

To install create a UPDATE folder in you game folder and put it in there

And the others firmware? newer ones? is no a good idea?
I saw something about a modified firmware 2.71

just get to 1.50 and then ask from there

To H3L10: what you should do is upgrade to firmware version 1.50 and then move onto 2.71 SE-B. You can virtually run all 1.0 and 1.50 homebrew games and applications on it. It's the best custom firmware around, all thanks to Dark_Alex! :)

you can 1.0 homebrew on 1.5 with custom firmware

true, but 2.71 SE also allows the running of all UMDs up to 2.71 firmware UMDs(possibly some of the 2.8+ firmware UMDs in future updates)
