Look for some free space in that bank where you can put a JSR to it followed by an RTL. And post the address if you haven't already.  |

Hi,
I have been using Geiger's debugger for a few days now...most helpfull hacking tool i have found in a long time!
I found the actual address although I will have to modify things a little since it seems to do a RET when i would need it to do a RTL...I didn't just chance it to a RTL though since i do want yoshi's fireballs code to still work  it shouldn't be a big deal do take care of when i get the chance although i'm not too sure when that will be.
my notes are at home so i cant post the actual address at the moment, I'll add it to the ROM/RAM thread when i get a chance.

I wouldn't know, but I'll bet if you used tracer and used Yoshi it might work. I'll be honest in saying i have no idea what i'm dong, but I'm trying to help, Right? |

I should be able to figure out the sub routine location of yoshi's fireballs now
I figured out that 7E1616 is the flag that tells us what item is in Yoshi's mouth.
If that item has a value of "04" then he will spit out fireballs each time you hit the proper button....from here i should be able to figure out the code that spits out the fireballs.
Thanks |
