To clarify my steps... And add a safety feature to it lol...
1. Play hard to unlock the other difficulties
2a. Skip Hardcore. Play through on Oldskool.
2b. When you reach the objective where you must destroy the plane, quit the game via the in-game menu.
2c. Backup your save... +, USB, another user account etc.
2d. Load the game and continue. As soon as it begins, Lower the difficulty to Hardcore. Prepare to quit via the XMB as soon as you pop Payne In The Ass. You do not want to give the game the chance to save, which it will do after the cutscene.
2e. Load the game and continue. You are still on Old Skool (Like you never changed the difficulty). Destroy the plane and pop Maximum Payne.
The cutscene is not short, so there is plenty of time to quit before it saves.. But have a backup just in case.
Almost messed this up. Saved game but finished on Old School without changing to Hardcore. Maximum Payne popped. Luckily I had save at the beginning of the hanger section on PS+. I deleted my game data on my PS3 then loaded the PS+ save. I had to play Old School in the hanger again then switched to Hardcore during the plane section to get Payne in the Ass. lol Got it done though. Thanks for the post.
