In Devil May Cry 3 by using infinite double jumps code at the very end of mission 17 it is possible to jump over invisible wall that triggers mission end and explore locations from next mission. There every room is considered as cleared with no enemies and open portals. Secret mission is still accessible. The samsara item is there, but is not obtainable, so we can't go further to Arkham's dimension. If we come back to top of the tower and go downstairs then we reach the end mission screen. Doesn't matter which region or version you play, regular or Special Edition, it works in all of them.
