PC 800B068C
SB T6 0x2089 (AT) ; 80062089: [T6 03] but how
---------------------------------------------
try #2

PC 800B057C
SB T4 0x2088 (AT) ; 80062088: [T4]
BEQ R0 R0 800B05AC
ANDI A1 A3 0x0800 ; [A1 0000] = [A3 0011] & 0x0800

ANDI T1 A3 0x000F ; [T1 0001] = [A3 0011] & 0x000F

ADDIU T2 R0 0x0005

JAL 80011BF0 ; that's guRandom() for those of you following along at home.
NOP ; delay is a nop, nobody gives a shit about nops. back after guRandom.
...
PC 800B0658 is the next stop
BEQ V1 AT 800B0688 ; and so it jumped

LUI AT 0x8006
SB T6 0x2089 ; 80062089: [T6 03] ; that's the arena byte alright

then when it goes to the handicap screen, breakpoint is triggered again.
PC 800B05A8
SB V1 0x2088 (AT) ; 80062088: [V1 01]
LBU V0 0x06 (A0) ; [V0 03] from 80062056
LUI AT 0x8006
ADDIU T9 R0 0x06
BEQ V0 R0 800B05DC ; no jump
ANDI T1 A3 0x000F ; [T1 0001]
BEQ V0 T0 800B05E4 ; no jump, [V0 03] != [T0 01]
ADDIU T6 R0 0x02
ADDIU AT R0 0x02 ; (was [AT 80060000])
and it just seems to go on like the above.
