#14861: M4: Orion Burger demo crashes when using the hamster wheel
-------------------------+-------------------------------------------
Reporter:  antoniou79    |      Owner:  (none)
    Type:  defect        |     Status:  new
Priority:  normal        |  Component:  Engine: M4
 Version:                |   Keywords:  demo, crash, drawing, palette
    Game:  Orion Burger  |
-------------------------+-------------------------------------------
 This is on Windows 10, with a local build from current master HEAD,
 2.9.0git with the interactive demo from the ScummVM website.

 Steps:
 After starting the playable part:
 - climb down the chutes until the bottom level
 - Use the hamster wheel.

 ScummVM will crash with no error message, not in the default debug level
 at least.

 In comparison, when demo is run with DosBox, that animation plays out
 fully, the door is raised and then lowered.

 There are a few other discrepancies I could spot with running the demo
 with DosBox:
 1. There is a drawing issue with the hamster wheel on ScummVM, when it's
 idle/unused, that DosBox does not have (screenshot attached). When the
 protagonist starts to use it, in ScummVM, its proper colors are restored.
 2. The main menu for the demo when run with DosBox is minimal and
 different than the one with ScummVM (for the demo). I suspect that ScummVM
 shows the menu for the main game here.
