I also compared the differences between the two file; battlea.j2l has 100 bytes more than battle1.j2l.



Some don't know this: Battlea.j2l contain thorns and events that are added or that won't work (especially the Generating Bird. The bird in the cage doesn't appear in Multiplayer; however, in Single Player mode, it regenerates immediately when you leave the screen).



Both levels's secret room has no differences though.
