;$3C5: $00: Unset, Will put Link in his bed state at the beginning of the game. (Also can't use sword or shield)
|
|
; $01: Start in the castle on start up.
|
|
; $02: Indicates you have completed the first Hyrule Castle dungeon.
|
|
; $03: Indicates you have beaten Agahnim and are now searching for crystals.
|
|
; $04 and above: meaningless. Though, you could write code using them to expand the event system perhaps.
|
|
|
|
;$3C6: Progress Flags (bitwise)
|
|
; 00 - Set after your Uncle gives you his gear in the secret passage. Prevents him from showing up there again.

|
|
; 02 - Set after you bring Zelda to sanctuary?
|
|
; 03 - Unused? (98% certainty)
|
|
; 04 - Set after Link's Uncle leaves your house. It's used to prevent him from respawning there.
|
|
; 05 - Set after you obtain the Book of Mudora (this is a guess)
|
|
; 06 - Seems to be a persistent flag that toggles between two possible statements that a fortune teller can give you during your "reading".
|
|
; In other words, don't expect this to stay in one state if you're using fortune tellers. Has no other known purpose.
|
|
; 07 - Unused? (98% certainty)
|
|
; 10 - Start value (in house, bed)

|
|
; 07 - All crystals shown
|
|
; 08 - Agahnim (skull icon at Ganon's Tower)
