Hide Your FC
#1
Hide Your FC

This code will spoof the FC that is sent on your USER packet in Mem90. If anybody is viewing the USER packets (via a RAM viewer or packet sniffer program) of a race/WW, they will read your spoofed FC. If you are too lazy to fill in the values, you can simply nop the address to put the FC as 0000000000000001 (0000-0000-0001).

And No, this doesn't hide your FC on the Wiimmfi MKW page.

XXXXYYYYWWWWZZZZ = Spoofed FC in HEX.

For example, if you want the spoofed FC to be 2468-0990-5553. Put that value in a decimal to hex converter (with no dashes), and use the hex result for the code.
