I had another issue finding the new value for $HEADER_SIGNPOST_RUN which caused game crashes right before opening a chest.
On the gwca git repo the constant equivalent is this one (which is harder to find because of names difference):
Code:
#define GAME_CMSG_INTERACT_GADGET
So new header for $HEADER_SIGNPOST_RUN:
Code:
Global Const $HEADER_SIGNPOST_RUN = 0x50
Everything works fine now, at least for boreal chest run
