I began disassembling the sprite code bank to find unused sprite code not even pointed to by any used or unused sprite.

Two days and about 3600 lines of disassembled code later, I realized that it was worth it.

Change Rex's (will probably work with other sprites too) ASM pointer to 87D9. This will create six sprites you can stand on. Standing on sprite 1 moves sprite 2, 3, 4, 5 and 6 to the right. Standing on sprite 2 moves sprite 3, 4, 5 and 6 to the right. Standing on sprite 3 moves sprite 4, 5 and 6 to the right, etc. Also, they will follow the ground.

My theory is that it was the beta "floating skulls" sprite. (It's code starts right before the final skull code and it uses the same tiles.)

If I find any other unused sprites, I'll post them in this thread.

I'd try this out immediately but I have no idea how to change Assembly pointers.
Perhaps you could take Legoman's advice and fill us up with some screenshots, if not a patch of such?
Thanks in advance. This sounds incredible.

Interesting find. I'd try to utilize a sprite like that in my hack, if I could space them out and give them seperate graphics (number them)

I made a short level with the sprite in it.

Download it HERE.

I can definitely see why this was removed

It doesn't seem to work properly for me -- one of them will always be in the same spot but will occasionally move around

So you end up making a gigantic string of platforms that is hard to cross, or even worse pushing them so far off that they disappear...

I can't get this patch working. I keep getting a corrupted ROM when trying to apply it on Super mario world(U)[!]

The ROM I used to create the patch is clean (yes, I checked before making this post), so either you've got a crappy IPS patcher, or your SMW ROM isn't clean.

...

This is awesome. It took me a few tries to figure it out, and then a few more to properly use it. This is great. I like it.

A few, if not many, more possibilities for level design have been opened.

Now, if I could only get the motivation to start hacking again...
