I am trying to get non-patched GBA roms. Also, if I want the complete sets of roms should I be obtaining the merged sets? Are the merged sets patched or trimmed? Please excuse me if I am using the incorrect terminology as I am still learning about all of this. http://grn.dl.am/ seems to have roms up to the most recent releases although it appears that once they are unzipped they need to be renamed from a .bin extension to a .gba extension (At least for Visualboy Advance to play it; is this true for carts/cards in a GBA SP?). Are there torrents or eMule links that will provide what I am looking for? If someone could explain the difference between merged sets and clean dumps I would have a better understanding of this too. Thank you.
