So I decided to play around with this game some more, found out GHM3 was out, was deeply saddened by the change in code format, but decided to see what I could do... I didn't have the time or energy to fix all the codes, but I did manage to create an updated version of the slot1 codes. Someone can use this as a base for updating the rest of the codes.
GoHanMem 2.0 format
#1Slot_1_80@0x84AFA69A @1 @80
GoHanMem 3.0 format
# slot1_80
@0,0,0x84AFA69A,0,0x00000000,0,0,0x00000000,1,80,0,0
GoHanMem 2.0 format
#2Slot_1_80@0x84BFA69A @1 @80
GoHanMem 3.0 format
# 2_slot1_80
@0,0,0x84BFA69A,0,0x00000000,0,0,0x00000000,1,80,0,0
GoHanMem 2.0 format
#Code Description
@0xoffset @size(byte,word,etc) @value
GoHanMem 3.0 format
# slot1_80
@0,0,0xoffset,0,0x00000000,0,0,0x00000000,size(byte,word,etc),value,0,0
All those extra zeroes seem to be related to pointers or range manipulation.
I may play with this some more tomorrow..but right now, it's bed time.
