Well, its nice to see an 11 yr old trying to do somethin the only ones I ever meet on socom are the ones that yell and "hahah I can hack and you can't hahaha". Anyway looking at the subs it looks like you made the hook jump to the same place in both subs mabey you ment to have the 0x08600064 the same as your first sub. And for a little tip if you have an nop (0x00000000) as the hacked value you could make it like this

hook
lui t0, $[first four digits of the address]
sw zero, $[last four digits of the address](t0)
jr ra

wich simply makes the address an nop with out having to load anything extra.
