Backup.zip contains only the original files that were modded, the whole smash is less than 1 meg so a backup of the entire game wouldn't fit in there.
Allegedly this is the JGSME version;

Personally I wouldn't bother, I looked over some of the files and he has zero set for all the enemy AI detection capabilities, with one million hit points and one million armor for all the player subs in the ZON files. I didn't even install it, if the enemy can't even see you to shoot at the hit points and armor are superfluous anyway. This mod changes it from a simulator to nothing more than a kid's arcade game.
