Remapping buttons/Making Dpad usable/More than 3 C items

[Jabba]

I was wondering if its at all possible to use more than three C-button items. For example, if you wanted to have the three items in < v > and have say your slingshot as your b button? 

 

The main reason I was thinking about it was because I was wondering if the D pad was usable? My initial idea was thinking about mapping items from the equipment subscreen to it and access them without having to pause the game.

 

I have a feeling its probably a hefty task and the answer will be something like "You have to do ASM" lol.

 

Suggestions?

You can read controller input and store custom items id's in RAM, then when the user presses the d-down have it call the function that uses a c-item.

 

Making the icon appear on the screen tho, I have no clue.

You would have to clone the code for the HUD for the C-buttons, design your own textures, map the textures, and re-position the newly-created hud to wherever you want it.

 

You would also have to make the items map differently to the d-pad also, or else you just have 2 c-button HUD icons.

 

It becomes a bit complicated, but surely it's likely possible. You will have to add a new routine when the D-pad is pressed in the item menu, or change what the input is supposed to be. It might be a simple byte change.

Well, I know that pressing a c-button or putting an item on one calls a function, so perhaps someone could write a new function to a code cave? Not me though. LOL I'm still learning MIPS. (I can't wait til I can do stuff like that though ^.^)
