Save Context
The "Save Context" is a term used to reference the z_common_data structure, or the home address of the variables saved by the game. Since the save file is created by copying the 0x???? bytes from the start of the save context, it's possible to peek in ram to determine what each save variable does.

Structs
Scene Flags
There are two sets of scene flags in Majora's Mask, permanent and the cycle scene flags. Permanent scene flags start at Save Context + 0x00F8, and persist for the lifetime of the save, while cycle scene flags are located at Save Context + 0x42F4 in the Japanese version and Save Context + 0x3F68 in the international releases and persist until the end of the current 3 day cycle. Both share a similar structure:
0x00 Chest Flags 0x04 Switch Flags (0x00) 0x08 Switch Flags (0x20) 0x0C Room Clear Flags 0x10 Collectible Flags (0x00) ## 0x14 //size of the cycle scene flags ## 0x1C //size of the permanent scene flags
