Help! Diddy Kong Racing cheat not working

I am running PJ64 1.4 with Jabo's Direct3d7 1.40, Jabo's DirectSound 1.40, and Jabo's DirectInput7 1.40. Diddy Kong Racing is (U) v 1.1 and I have verified it is good with GoodRoms lastest version. The game runs fine, but when I try to activate the cheat to stop the octopuss boss from moving in adventure mode, it just turns diddy invisible. The boss keeps moving and I lose again .
Oh yeah, this is with the latest version of PJ64 cheats Beta 1.4.4.
Has anyone got this to work?
Thanks in advance for any help.

Never mind. I don't need it now. I finally beat the octopus boss.
Wish there was a cheat for the walrus boss.
