Disable Engine Pitch Sound Limit [Ro]

Posted by: _Ro - 02-28-2024, 06:21 AM - Forum: Visual & Sound Effects - No Replies

Disable Engine Pitch Sound Limit [Ro]

This code removes the vehicle's engine pitch limit, if driving at max speed normally, no difference can be heard, but if using speed hacks, the pitch different is noticeable and the fastest you are, the highest the pitch is. This code will make the vehicle sound exactly the same when you use speed hacks in MKDS.

Balancing Code Request

Posted by: DracoTH - 02-06-2024, 05:48 PM - Forum: Code Support / Help / Requests - No Replies

I have been testing out some codes, specifically the MKDS Snaking, Mini Turbo boost is Mushroom boost, Wheelies don't lose speed while turning and wheelies don't time out, and I realized that I made karts way too powerful with that combination of codes.

So I had an idea, but I don't really know nor have the requirements to make a code, that's why I'm requesting here.
My idea is to make a code that makes mushroom boost speed lower to balance it out, or one that makes wheelie speed higher for the same reason, I don't know if it's possible, but if someone could do it, it would be greatly appreciated.

Set User Favorite Combo as Defaul like CTGP [Bully, CLF78, Kazuki]

Posted by: Kazuki - 02-01-2024, 12:22 AM - Forum: Offline Non-Item - Replies (2)

Set User Favorite Combo as Defaul like CTGP [Bully, CLF78, Kazuki]

Set the default combo to the most used character and vehicle in the upper left license.
If the upper left license is empty, the upper right license is used, if the upper right license is also empty, the lower left license is used, and if the lower left license is also empty, the lower right license is used.
Mii is excluded.

This code uses 0x800011DA

Hi, I'm new here! Smile

I've played Mario Kart off and on for the last 10-15 years or so as I've found it to be a fun game to play with friends and such. I'm not great at the game (sometimes I even *gasp* lose to some of the CPUs) but even so I have fun playing it.

Learning about different things with regards to the game, seeing what everyone has discovered (and what remains to be discovered), and how it works has also intrigued me. Mario Kart Wii was my second Mario Kart game that I've ever played (after Mario Kart DS).

Anyway, I hope everyone here is having an excellent day! Smile
