#START ASSEMBLY

#Address
#NTSC-U = 800E7E74

#NOTES:
#LR safe
#r0 safe after original instruction
#r27 thru r31 safe for use
#r29 (before original instruction) + 0x1A68 points to player 0's structure
#Structure layout
#0x0 (word) Bit layout: (flip high for yes, low for no. only 1 bit can be high at a time ofc)
#Bit 13 = Final Opponent
#Bit 15 = Human (1P/2P/3P, etc etc...)
#0x4 (word) = Character (last character listed is always final opponent)
#0x8 (word) = Always null?
#0xC (word)::
#00000001 = 2P
#00000002 = 3P
#.. ..
#00000007 = 8P
#0x10 (word) = Slot on current bracket state (always 0x1E for final opponent)
#0x14 (word) = always null?
#0x18 (word) = always null?
#0x1C (word) = always null?
#0x20 (word) = always null?

#Increment by 0x28 to move onto next player/structure

#Original instruction; store final slot value of current bracket state to last regular character

#Now flip human bit high for final opponent (aka character 17) which is listed right after last regular character of bracket in memory
