Nope, this code still doesn't work.

Last view: 594 days ago 		So, where do you suggest I should hook it? Possibly the power up class constructor?

Also, I should add that it freezes when I choose the star.

Last view: 3744 days ago 		Well, with the exception of your write offset being 0x15 when it should be 0x1B, your code checks out. But I don't have a Wii to test it on, so I only tested it using Dolphin.

Last view: 594 days ago 		I'm pretty sure it should be 0x15, because 18 + 3 = 21, and 0x15 is 21 in hex.

Last view: 3744 days ago 		Sorry about that, I listed it in the Wiki as 18, but it's 0x18. 0x18 + 0x3 = 0x1B...

EDIT:

Hey MN1, if you haven't got it running already, can you try patching the game using these patch strings and seeing if it works?

Last view: 1261 days ago 		It's not that simple SSL. This is existing code that is being corrected and called in teh right order to work again. That has no real code, we would have to look extensively to reverse engineer, then find functions in SMG2 that are the same, send new info to them, and patch it. This thing that he did in a few nights? Yeah, that will probably be a few months, so check back then.
I don't think you quite understand ASM hacking, so I would kindly ask you to put your childish desires aside and have patience while we gather info on more functions to make this POSSIBLE.

Last view: 1261 days ago 		Well think of it this way. It's not about the powerups. It's a way to test what we know and can do on something that has existing code but is broken. It's basically step 1. Once we have the basics down then we can move onto something simple that we can port. We would debug to find memory values and then find functions. Once we know what functions an object uses then we can find the same functions in SMG2 and start to call it and patch in teh new code. However, debugging takes time since PW is the only one with a USB gecko to make it easy. MN1 and MM are doing it by dolphin and by hand. So it takes even longer. It's for this reason that you have to have patience. Once we finally port a simple object over to SMG2, we can move onto something bigger, and try again. We would repeat this process and eventually have lots of functions and we can do a lot. But this point of knowing a lot is YEARS off.


Take Bean and chadderz for example. For the multiplayer they are doing the same thing, they are editing and changing the memory to make existing code work in new ways. It's the same way with the powerups.

Last view: 1261 days ago 		Yes, however, all they did was resize screen dimensions, which is simple, and create 2 running instances of cameras and stuff. All it is is simple resize and "duplication", though duplication is a very specific context.

Last view: 3744 days ago 		I should probably mention that I don't have a Wii anymore - it's part of the reason why I quit most forms of serious hacking. These days it's just manually looking at data files or using Dolphin.

I haven't actually gotten a chance to test my code with 0x1B instead of 0x15. I will when I get home, and if that doesn't work, I'll try your code.

Nope, looks like your code doesn't work.

Last view: 3744 days ago 		Alright, I'm going to remove a possible source of error, but I have a feeling that we may be stuck if we don't have someone who can use Gecko. Try this patch:



<memory offset="0x803B6E80" value="38800003"/>
<memory offset="0x803C84F8" value="60000000"/>
<memory offset="0x803C84E8" value="3BFE15083BBE1518"/>

Unfortunately, with that patch, Starship Mario doesn't load.
