Information: the blocks can be moved unlimited (or until you hit an obstacle)

Update There is a bug that you can shoot with the hookshot through the in-move block; which is a possible bugsource. Use this asm to prevent that:

Code:


; it is possible to hookshot through the in-move blocks - which may result in unwanted effects
; this asm code will block this.

Code Addresses: 0x77e00 - 0x77e1c (after pot with sword destroy and icerod freezing water above); restricted to power/titan gloves use 0x77df0 - 07/7e22

Uses free ram (7F/5000 0x1)

ASM for no restriction (always move unlimited times, have glove or not):

Code:


; This ASM was written by Conn
; This is a ASM FrontEnd Code for Zelda ALTTP (US, no header) to move blocks multiple times.
