Most of the time you'll have to patch into them to have them jump to some free space elsewhere. All you really have to do is replace as many instructions of it as you need with a jump/call, and make sure to execute those instructions somewhere in your new code.

come on, just release it to everybody...

that remind me, I should release my metroid code

edit: enter this code in MWR: 000012041080E78F0DE8 over a sprite
after, go to an empty area and enter this code: (replace the XX with the sprite number)

08 E2 30 B5 9E C9 XX F0 0C 28 B9 D7 8F 95 B6 B9 DF 8F 95 AA 6B A5 97 DD D4 14 90 10 F0 02 80 16 A5 96 69 08 D5 D8 90 04 F0 08 80 0A A9 F0 95 AA 80 08 74 AA 80 04 A9 10 95 AA A5 95 DD E0 14 90 0E F0 02 80 14 A5 94 D5 E4 90 04 F0 08 80 0A A9 F0 95 B6 80 08 74 B6 80 04 A9 10 95 B6 28 6B

then go to 0x91FE and put a JSL to the code you have entered and finally change 0x9202 to 0x9207 by EA, I will post the disasambly soon

note:this is the version without the glitch

xF4FF the subroutine for yoshi's tongue

sound effect adresses:

xF957 SFX that is played when Yoshi's egg breaks.
xA4C6 SFX that is played after the egg is broken.
xEF60 SFX that is played when Mario jumps on Yoshi
xF50F SFX that is played when Yoshi's tongue comes out.

Dude, you are doing things way beyond the scope of most beginners. I don't really consider myself a vet, really I'm not that great at all, but you've come into this way ahead. Don't sell yourself short .

I don't know how much help it'd be, but there is some pretty in-depth stuff at http://www.zophar.net/tech/snes.html

I was going to post this a few days ago, but I was bored so I wanted to see if there actually was a quick way to change yoshi's color and behavior - mid level.

I used Geiger's Snes9x Debugger and set a write breakpoint on $7E13C7. Turns out this value was getting updated every frame from a location in the array at $7E15F6, X. I don't know that location very well, but it appears to be in the middle of a group of other sprite information. This says to me that Yoshi is just another sprite object on screen that Mario interacts with... am I wrong? Like, is he in the same class as the enemies or is he seperate from them.

Anyways, if you can locate the entry in $7E15F6, X that corresponds to Yoshi, you can change his color to one of the values listed (4, 6, 8, A) and his color and behavior will change within the next frame. I could not figure out how the game knows which entry is Yoshi's since Geiger's isn't as advanced as I wanted it to be. That would have required breakpoints on things like writes to the X register, and being able to filter out certain addresses when using breakpoints. My point is that Yoshi is allocated as soon as he gets on screen, just like any other sprite, and thus his entry could appear at $7E15FE, $7E15F8, or any other byte in that array. I suspect the array is only 10 byte long but again I'm not familiar enough with this game to know for sure.
