Boot into any menu [Melg] - Melg - 04-10-2022
This code boots the game into a specified menu. By intelligently selecting which menu to boot into, you can start the game directly into a screen of your choice. For example menu 0x49 "Single Player (coming from Time Trial Change Character)" will boot the game directly into that screen.
Please note that the code should be seen as a base. Some menus will work as is, by just changing the menu ID, but others will need some values (such as character, vehicle, number of races, etc...) to be initiated. Considering the sheet amount of menus (roughly 150), I did not make a version of the code for every single one of them.
Refer to: https://mariokartwii.com/showthread.php?tid=1950 for an example on how values should be initiated. The exact hook and method will differ depending on the menu, but it still gives a good idea of what to do.

In case you're wondering what happens when you don't initiate any values on menus that evidently would need to...it either crashes or you get the default values. Here's me booting into menu 0x20 which is single player Versus Mode (yes you can boot directly into a race):
RE: Boot into any menu [Melg] - Zeraora - 07-26-2022
NTSC-J and NTSC-K L values are filled in.
RE: Boot into any menu [Melg] - Zeraora - 11-26-2022
One question I wonder is if there is a way to change certain menu transitions.
Let's say after you complete a VS Race, instead of bringing you to the "pick a track screen" you could change it to a different menu, maybe the credits or something.
In theory, it shouldn't be too hard, simply re-use part of this code at the address that controls the new menu transition.
RE: Boot into any menu [Melg] - seanmcnally - 03-22-2024
Thanks for this code. I'm wondering, is it possible to boot into a specific page of a menu? For example, 4 players, character selection screen?
RE: Boot into any menu [Melg] - Cealgair - 03-25-2024
It is. I see the Wiiki page that was linked has since been extensively modifies. Here's a link to an old version that has what you're looking for: https://wiki.tockdom.com/w/index.php?title=List_of_Identifiers&oldid=332888#Menu_Identifiers
