SSBB: How to calculate a FC using a PID?

Does anyone know, how to calculate a Smash Bros. friend code from a given profile ID?

I ask, because Smash Bros differs here from all other games and uses another algorithm to create the checksum. And I need it for the statistics pages.

Hmm..

We already know that SSBB has a few "errors" in the net code (for example, the keepalive is sent by the server and not by the client). Maybe it'd a good idea to try a few modifications of the FC function?

(I can't compile C code so it's untested if one of these codes works):

Test 1

Test 2

@Leseratte and all other:

Use this php script for tests and add some other SSBB FC:

ssbb.php

The MKW codes are only for verifying. Add more SSBB codes. Modify the function CalcFC() to find a new algorithm.

Call the script with: php -f ssbb.php

EDIT:
I have added some more smash codes.

I made some more tests without succes. And here is an updated script:
* download.wiimm.de/wiimmfi/calc-ssbb-fc.php.txt
De-comment or add lines for testing.
