RAM: Bank 0x7E: Page 0x01

This is a subpage of RAM

This is beyond direct page and you can assume that all addresses here are $7EXXXX until you reach bank $7F.

• $0100 (02) = Numerical index that controls the graphics that are blitted for Link during VRAM. See DMA variables for additional info.

• $0102 (02) = See DMA Variables
• $0104 (02) = See DMA Variables
• $0106 (01) = free ram?
• $0107 (02) = See DMA Variables
• $0109 (01) = See DMA Variables
• $010A (01) = Set to nonzero when Link incurs death. Used if the player saved and continued (or just continued) after dying, indicating that the loading process will be slightly different.
• $010B (01) = free ram?
• $010C (02) = Temporary storage for a module number. Example: If we're in Overworld mode (0x09) and have to display a textbox (module 0x0E), 0x09 gets saved to this location on a temporary basis. Once the textbox disappears this module will be resumed.
• $010E (02) = (Dungeon) gives the entrance index of the current dungeon
• $0110 (02) = In the context of loading dungeon rooms, contains the index of the room (see $A0) multiplied by 3. Allows for indexing into 24bit pointer address tables.
• $0112 (02) = Apparently a flag indicating the bombos medallion is falling. Stops the Menu from being dropped down too. It seems to work as a flag for any general extended animation that is currently in progress.
• $0114 (02) = Value of the type of tile Link is currently standing on. Only the lower byte is used.
• $0116 (02) = Used with routine $008CB0 to transfer 0x0800 bytes from $7E1000 to a variable location (determined by this memory location)
• $0118 (02) = Local portion of an address used to transfer data from $7FXXXX to vram whenever variable $19 is nonzero.
• $011A (02) = BG1 Y Offset. Gets applied to $0124. Can be used in quakes/shaking
