Help trying to create a custom character

I'm trying to create my first custom character using a sprite I created, and whenever I send the file it always says the following:

"Your character width must be a multiple of 24."

My character width IS a multiple of 24.
I don't know what to do.

I'm using the kart sprite from SRB2K by the way.

idk how to help, sorry.

Yeah, that's okay. I'm sticking with the SNES kart template, for now.

Ok. Anyways, If you wanna be admin or mod in my topic, Only Mario Kart Talk, then here is the link: https://mkpc.malahieude.net/topic.php?topic=9411 Please Have A Good Reason To Become Admin Or Mod, We Won't Give Mod Or Admin If You Don't Have A Reason Or If You Don't Have A GOOD Reason.

I know about that topic already, but thanks!

Hey there, as someone who has made characters even with SRB2Kart's kart, it's always a good idea to use Mario's sprite sheet as reference, which you can easily save as an image to use as a base. SRB2Kart's sprites may not include as many angles, so I recommend you split the angles you have onto the several more the SMK sprites have so they match their angle.

I managed to get it to work, but now it has a weird animation and it looks really ugly.

If that's the case, do you mind showing your progress here so I could try to fix your issue?
