Issue title: Suggestion: change the internal name of the generated ROMs so they don't share save files.
 Issue body: The emulator I use, Mupen64Plus, uses the same save file for all ROMs with the same internal name.  This means I can't switch back and forth between playing the original Majora's Mask and a randomized version without completely deleting my saves in between.

A potential solution would be to rename the generated ROM.  The new name would incorporate the seed used to generated the ROM, as well as a hash of the settings used.  That way each generated ROM could have its own save file as well.

 Comment 0: I believe this would also allow us to install multiple WADs on Wii, because right now if you try installing another seed it will overwrite the old channel & still have your old save.
 Comment 1: If it uses a sep save hd packs won't work
