Mach 4 Crash: Known Issues

On Startup

Data Files

Mach 4 relies on a number of data files, early in the startup/initialization process. If any of them are corrupt, this can cause immediate crashing.

Corrupt Mach4GUI.ini

This INI contains settings saved from the last run, like window size/position and a few behavioral settings that are "global" behavior rather than profile-specific behavior.

Symptoms

  • happens before screen load
