N64 CRC not working?

[BGNG]

In the F-Zero X ROM (North American; Non-Byte-Swapped(Z64)), at offset 0x6E310, the text "mute city" is found, which is used by the game to display the name of the course in various places like the intro to each race and on the records menu.

Changing this text to "mote city" in a hex editor, I get a notorious "infinite loop" error when I load the ROM in an emulator. I've tried a zillion and two different CRC calculators, none of which seemed to correct the problem.

Anyone have any insight on this?

The CRC tool should fix it. Worked for me for GE.

"The"...

Which tool are you using?

EDIT:
Scratch that. I finally found one that works.

Now, as far as CRCs are concerned... How would I go about generating/fixing those myself?

Edit2:
F-Zero X uses the CIC_NUS_6106 boot chip, so... if you can find the algorithm for that one I'd appreciate it.
