I want to be able for the player to access the inventory in level by pressing select.

2 problems.

1) I don't know how to edit so it does that
2) I hacked the register that controls if you're in your inventory or not, and even if you do use an item, it doesn't work, because of the style of initiating the powerup is different I think, but stars do work.

I just got this really REALLY good idea.
I'm really sure it's possible with some ASM hacking.
Ok, if you were to get my idea to make items you pick up usable during in play, you could actually do something really cool.
You could make it so where instead of instantly using items, you keep them, like Mario RPG or something. You can access inventory by pressing select.

Now, you'd need to replace power ups with the treasure box effect.
Replace the spawning sequence for item blocks with the spawning sequence for when you touch a treasure chest, and recode the thing that identifies whether the box contains a fireflower, leaf, or whatever, into the code that adjusts what's inside a chest.

This would seriously be freakin awesome.
