Scripts are technically copyrighted works so sharing them with all and sundry is not always the done thing. Similarly the "simple" games can be simple but for traditionally low on text things like puzzle games you can just as easily find yourself with a complex file format and most text in it being in the form of pictures rather than encoded text.
To go further scripts can often include an awful lot to make the programmer's life easier (commands to make text bold, italic, coloured......) as well as other programming oriented things. http://www.loekalization.com/mistakes.html
makes nice reading at this point.
A good hacker can work around such things and present you with text capable of being translated though I will say if you can deal with some markup type arrangements it does help.
Normally I would point you towards some of the hackers that deal with the language you expressed an interest in but I am afraid I do not know any, Brazilian sure and going back there were a few (though without checking I probably should make a disclaimer and say they might be Brazilian too) but right now I do not know of any.
Still I should say gamefaqs seems to have a few for various games, for reasons mentioned above they are not so useful for hackers though.
