mac help

hello all.this is my first post on here. i have found this site quite helpful but i have a problem i still need help with.when i download a game and unzip it, it is a document file and not a .nds (unix executable file). it is driving us crazy as we cannot convert or change them.please help. could it have something to do with us using a mac? i use unRaR to extract.cheers.

What game did you download, by any chance? Is the extension of the file ".nds" ?

i downloaded the don king boxing game and another called "imagine doctor".yes they are .nds files, but when i extract them they are documents, not unix executable files

they arent supposed to be executable files. They are binary files that must be run in an emulator or on a flashcart.
