Region ID Changer #3 [Vega]

This code allows you to set a custom region ID when connecting online. The code only effects the Region ID when connecting online, thus there will be no prompt from the game to reset the data save due to a region ID change.

Position Never Changes Online [Vega]

Works online only.

Whatever position you start as in the race will be your position for the entire race. This also effects your items. Such as if you start in 2nd, you will get 2nd place items the entire race.

Please note that if someone DC's in the WW/room you are in while you are running this code, you may cause the entire room to stall once race has finished indefinitely.

Position Modifier Online [Vega]

Works online only.

This code allows you to select a desired position to have the entire race. If you set it to 1st, you will always win (on your screen). If you set the XX value to 00, the code does quite a bit of things: You always win, you always get mushrooms (legit mushrooms, not the 0x14 type), and you stick/freeze your GP points. Regarding the GP points (on your screen), all players will get 0 points. On everyone else's screens, you will always have the same GP points every race.

Another thing to note, that you will get whatever normal items are for the position you set. So if you set the code to 2nd, you will always get 2nd place items.

Wii ID Spoofer [Vega]

This code allows you to put in a fully customized spoofed Wii ID Number. Do not put a value over 002386F26FC0FFFF (9999999999999999 in decimal) or else you will have a negative/invalid Wii ID number and a server admin/mod will notice instantly that you are using spoofing codes. A value of all F's will render a Wii ID number of -000000000000001 (a digit will be missing).
