I have some in mind that could be fun to run, like Softlock%, Unlock All Doors and (All Bosses which still hasn't been added) I have videos for Softlock% and Unlock All Doors btw. Rules for these categories are simple, for Softlock%, it's just like Crash% but you softlock instead, for Unlock All Doors, you go through the missions on a complete file and unlock every door the game has to offer. All Bosses is just the same as LM2HD but you add up the IGT like in All Bonus missions instead of timing it.
