Here is the tool for you: http://www.asharer.com/download-video-sharer

Go to 4shared and search gba roms or or any other media for free, no download of program.

Www.limewire.comor www.itunes.com

My solution would be 2 download a torrent called Frostwire which allows you 2 search and download millions of files posted by other users. You can download games for all platforms, all media files such as music, video etc and much more. And also this program doesnt require u 2 sign up to it , you just install it and u can start searching straight away. However, it requires an internet connection and u need to unblock ur firewall. If you want it to work even faster, u can buy frostwire premimium but it is not required. I hoped this solved ur problem! =)
