This code hides the different countdown and "finish" text.

- First line: FINISH!
- Second line: YOU WIN!
- Third line: YOU LOSE!
- Fourth line: 3, 2, 1, GO!

On the first three lines, the BMG ID is modified to be zero, but you can change it to any BMG ID you want, by changing the last two bytes on each line. You can also remove any line you want if you, say, want to hide some elements, but not others.

This code allows the player to modify the countdown time before starting a race.

The values are:
- XXXX: The number of frames the countdown lasts. This is gotten by adding 1 to the number of seconds you want the countdown to last, and then multiplying that with 60 (or 50 if playing in PAL 50Hz). For example, for a 100 seconds countdown, this is (100 + 1) x 60 = 6060 (put 17AC in the code).

- YYYY: The number of seconds the countdown lasts. For example, for a 100 seconds countdown, this is 100 (put 0064 in the code).

- ZZZZ: The number of seconds the countdown lasts plus 1. For example, for a 100 seconds countdown, this is 100 + 1 = 101 (put 0065 in the code).

- RRRR (optional): This is the number of frames during the countdown where the player's nametag hides. This is gotten by substracting the total countdown time in seconds + 1 with the number of seconds you want the nametag to hide, and then multiplying that with 60 (or 50 if playing in PAL 50Hz).
For example, for a 100 seconds countdown, if I want the nametag to hide after 3 seconds from the start of the countdown, we do ((100 + 1) - 3) x 60 = 5880 (put 16F8 in the code). If you don't care about this, you can remove this line, but this makes the nametag hide three seconds before the countdown ends, as usual.

- QQQQ: The BMG ID for the first number displayed by the countdown. Every second, the game adds 1 to this ID, so you get the different text that is displayed.
This means that, if you want to display a sequence of strings during the countdown, they must be put one after the other when it come to their BMG IDs.
For the video below, I modified Race_E.szs to change the text there to have each number from 100 to 1 (and then GO!). Then, I noted down the BMG ID corresponding to the number 100, and put that into this code.

Slippery Ink [KooShnoo]

This makes the blooper ink slippery, just like it is mario kart 8 and mario kart 8 deluxe.
There are two variants, slippery and super slippery.
Slippery ink makes the kart act like it's on sand when inked.
Super slippery ink and makes the kart slip out and act like it's on ice when inked.

Known Issues:
I think that slightly slippery blooper option *increases* your traction on sherbet land because of the way i made it
you see, the slippery ink just gives you sand physics when inked
but sand is weaker than rSL's ice slipperiness >.<
unimplmented fix:

Select any Mii in Character Selection Screen (Single Player Menus) [B_squo]

Video

With this mod, when selecting a Mii in the character selection screen, you will be able to select any Mii from your console / a Guest Mii by bringing up the selection menu typically only used in Local multiplayer.
This code is offline-only, at least temporarily, in order to prevent situations where the player's Mii name would not match the Mii name seen by the Wiimmfi server, which according to that server's rules, it's banworthy.

The Gecko code itself won't work as is. You have to copy some specific files from MenuMulti.szs to MenuSingle.szs and Event.szs (otherwise the game will crash).

The following BRCTRs must be present in those files:

• /button/ctrl/MiiSelectArrowLeft.brctr
  
• /button/ctrl/MiiSelectArrowRight.brctr
  
• /button/ctrl/MiiSelectMii.brctr
  
• /button/ctrl/Back.brctr
  

• /control/ctrl/MiiBlackBack.brctr
  
• /control/ctrl/MiiSelectName.brctr
  
• /control/ctrl/TabControlMiiSelect.brctr
  
• /bg/ctrl/MenuObiBottom.brctr
  
• /bg/ctrl/MenuObiTop.brctr

Hey Guys, I have an idea. Does anyone think it would be possible to design a code that can make knockout mode work offline in the game. basically something simple like if you finish last in a race you instantly get eliminated and have to spectate the rest of the game until its over. just asking if that were able to happen cuz it would be quite fun to do. if not than it's cool. thx

Like in Mario Kart DS, Time Trials race start music is also used as Wi-Fi and VS Race start while in Mario Kart Wii for Time Trials it shares a sound entry inside the BRSAR with Battle and Mission/Competition/Tournament (using "o_Start2_32_fan.brstm") and VS Race shares its entry with Grand Prix (using "o_Start32_fan.brstm"). So I was wondering if there already was or if somebody could make a code which makes Time Trials and VS Race mode use "o_Crs_In_Fan_Wifi.brstm" instead of "o_Start2_32_fan.brstm"  and "o_Start32_fan.brstm" for their race start themes.
