Unbreakable shells:
Try to find the counter that tells how often the green shell has already hit an obstacle until it breaks.
Not to hard to do.
Modify item maximum:
Spot the correct address(es) that tell how many items are allowed and get the correct ASM to hook.
I think that the maximum item limit must be designed before the course is loaded. Maybe some stack calls are needed.
Try to set a new maximum using a li instruction. It definitely isn´t an easy code to make, even though it can be made in 1-line.
Blue shell speed:
It´s a constant float indicating the default blue shell speed, it´s already released by mdmwii
Blue shell position:
x,y,z item coordinates like for the player (interesting thing for codes, stuff like item riding can be made)
Btw. the video is super awesome
@dxc2:
If one shoots more than 1 blue shell, the previous one vanishes. So there won´t be such a dragon fly like in the video, doesn´t matter how the "activate item" button is hammered. Same for all the other items, just that the limit of items that are allowed to be in use *at the same time* is different! For e.g. green shells, some more are allowed to be in use. Since you have MKWii, you should know
