It's amazing that even as the game reaches its 6th year since the original release, that new things still emerge from it.
This time, using assistance from Prof.9, I was able to get only one battle to load when playing against another person in multiplayer. Using a cheat, it's possible to have them fight on your side, though with odd, annoying side-effects. However, it is possible for both players to fight together, even for a while. Another possibility would be to allow players to fight with AI-controlled opponents. Even so, there are still restrictions to what is allowed since multiplayer battles only allow uncompressed sprites to load. I hope some of the bugs get fixed so the potential of this could be further explored.
