It's a bit hard to get Zsnes to compile... You need not only SDL ( http://www.libsdl.org/
) but also Assembler to compile it (http://www.rocklinux.org/packages/nasm.html
). If I'm not mistaken, it was used assembler to emulate the sound of Snes into Zsnes as they did with Final Burn for Linux...
The first adress is correct, but I'm not sure about the second. Anyway, if it's wrong make a search on google after NASM...
Install first SDL and NASM, then try to compile Zsnes. It should find automaticaly those libraries. Alternativly, you could use Snes9X. It's not the same good as Zsnes (odd audio output in some games (Super Street Fighter and Megaman X series ) and some games runs bad as the last stage of StarWars; A New Hope and bad support to special snes chips like SFX (Star Fox and Doom ). Yet, it's a great emulator and gets a respectable second place and easy, really easy to compile
