its a game crash. i used sgdeemer and opened the SDDATA.bin and it has my name there
e.g Kaz, so then i added aload of "a" so it was like
Kaaaaaaaaaaaaaaz <-- u get the idea (but more a's)

and then i got a crash.

I see you only got control over $v1 register. You would need to do some RE work to see if that's enough to be exploitable.
