There are several differences in the behavior of the original executable vs scummvm:

• Ladder to mailbox room instantly has you climb back up again (renders mailbox inaccessible)
• Incorrect timing for demo lockout screens in the plaza (can't walk to the locations before seeing the lockout screen)
• Incorrect lockout screen in the plaza (can't enter TNT building)
