Memory Access Violation

Memory Access Violation (also known as MAV) is the most common error message in Wonderland. It can appear in all five games and both editors, though it is more common in the Classic Trilogy games. The error appears when the program attempts to use a part of the memory that it's not authorized to use (therefore "violating" the computer's rules). Other various error messages include Parameter Must Be Positive, Abnormal Program Termination, Illegal Instruction, Unknown Runtime Exception, and General Protection Fault.

Known Causes

The following events can cause a Memory Access Violation error.

WA Editor: Clicking anywhere south of the level when in Tile mode.
Classic Trilogy: In rare cases, loading a hex-edited level can cause a MAV.
Classic Trilogy: Motherships at the edge of the level area attempt to create UFOs outside the level boundary.
RTW Editor: Loading a level with Metatiles will always lead to a MAV.
RTW Editor: When selecting a level to load, if the level list does not fill up the screen, pressing a letter key will lead to a MAV (the editor has to scroll down, which it can't).
