Race condition when reading the firmware settings

[AntonioND]

The ARM7 core reads the firmware setting right at the start of main() with readUserSettings(). Normally the ARM9 won't try to use this data for anything because it needs to load graphics and start the game/application in general. However, is it possible that the code tries to read the firmware settings before the ARM7 has had the chance to read them? This needs to be checked.
