Besides that, this thread is specifically about a new JJ2 level editor... Also, if the editor supported multiple games, it should really have a different mode for each game. Opening a battery check level file would mean, for example, that the editor knows not check for JJ2-specific errors (instead it would check for battery check ones, whatever they might be). Sprites would be loaded from that game's anims file, rather than JJ2's. And so on. This way, the editor would (ideally) serve every game equally well, in whatever specific ways are needed, rather than clumsily trying to support everything at once (to the detriment of everything else).
