Level loading cut scenes fail in Mupen when in "multiplayer mode", but switching to single player mode for the cut scene makes switching back to multiplayer mode a pain. Switching back after the first player has been loaded by themeselves will crash the game, and in the time the first player is playing alone, the effects of their data constantly being overwritten by temporarily unused multiplayer data could be seen and annoy the player.

Using the warp code to skip level loading allows for play, but there is no interface for its use. Programming the map menu to have the A button disabled and still allow for level selecting would work, but the level selecting would have to be triggered outside of the menu - warping in the menu crashes the game.

Finally, level loading cut scenes and similar are unavoidable anyway, as the progress made can't be saved unless they are viewed because they occur between the time scores are moved to the save area and the time the players regain control.

Possible solutions are to force players to either manually dictate the game mode and avoid crashes with difficulty, or to find some way to switch the mode to single player for those cut scenes and then somehow switch it back without causing a crash before player 1 is loaded and given control on their own in the wrong mode.

Note: Setting the mode to single player while in the map menu and then setting it back to multiplayer when the screen is completely black once the level loading cut scene ends allows for play; the usual screen splitting issues will still apply.

Better note: It seems using the warp code just once to warp into a single player level and skip the level loading cut scenes associated with that level will allow the game to be played normally with the usual menu hack (force screen splitting/single player menu hacks, specifically) from then on.
