can someone explain elf files to me? i first saw them in psx developement, and figured they're the psx executable file. then i saw them in ps2, so im like, well maybe sony kept them as the format of choice, but then i saw them with gba and now gamecube developement, so im assuming its a sort of universal bianary/executable file format used in *nix (aka open source) systems. if someone can explain more or provide a link or three, i would really appreciate it. thanks.
