the old build required it because he didn't want people to have it easy when adding "roms." the old precompiled version had a handful of homebrew and free roms inside of it. anyways you will find the emulator to be VERY slow on most games still. with no signs of updates in the near future. it may frustrate you but for the few it does work on, it works very well. i recommend giving superman a go.
