• Answer:

  1. yes you can 2. it lets you run downloded games (ISO CSO DAX) and it lets you run homebrew applications (stuff that sony didn't make like irshell and other stuff) 3. yes, it is illegal 4. yes you can 5. there are three ways. you can get a pandora battery and magic memory stick (i recommend that). or you can open your psp and remove the motherboard ad put another one in that has custom firmware (very dangerous). or you can open your psp and install a mod chip (dagerous). but to make the pandora battery and magic memory stick you have to have custom firmware to do it without opening the battery. because if you don't have custom firmware already installed, to make one will be VERY TOUGH. i recommend just going on ebay and buying one. you can't buy them in stores because they are illegal
