Hi Ralf,

The starting position codes work fine in all modes except for LAN mode, would you be able to disable the kart position randomization? That might fix it.

Hi Ralf,

Would you be able to make a fun gecko code that makes all character model heads bigger?
The idea is that everyone has a large head like Petey Piranha.

Co-op Mode: Swap Drivers Automatically When Ending Actual Lap [Ralf]

Hello Ralf! I really like this code. It improves the Co-op mode and makes it way more fun than the vanilla game. :D

The code is great, but I encountered one bug: whenever we use the Chain Chomp item right before the finish line, the game completely crashes. Is there a fix for this code?

I suggest adding a code that makes the Chain Chomp release automatically (meaning it goes forward immediately when used). That would be a useful fix for this issue. Because honestly, with the excitement of the race, we might unconsciously use it right before the finish line and crash the game, and that’s what happened when I played with my friend, unfortunately. xD

Just a quick reminder — Co-op Mode uses three buttons for item usage: A, X, and Y."

I also suggest adding the ability to swap players directly by Player 1 pressing Z, instead of requiring both players to press together.

Thanks a lot. 🌷🌷

The code is working correctly. The only issue is that it crashes when Chain Chomp is used before crossing the finish line, because the game doesn’t allow the player to swap while using Chain Chomp. I hope the point I was trying to explain is clearer now.

Thank you again. 💛

Hey Ralf can you create a code that the L Button use for items similar to Mario Kart DS, Wii, 7, 8/Deluxe and World.
