Also here I can tell you how to turn this code into a "Star Cloud" code. Decrease the fifth instruction by 0x30, (e.g. 76B5 from PAL to 7685) and change "38600008" to "38600004".

Fyi, this code is using an unsafe range in the Exception Vector Area.

Nice!

Thank !
The only problem is when you get hit by another item in the same moment of the end of TC, you cant have the star effect 

Please, can you modify this code and replace Star effect with Bullet Bill ?

I can't give a guarantee that I'll get it right, but I'll look into it.

[Jeffy/Wrath]

great code glad it is now just a gecko code.

Would it be possible to use the Mega and Star Cloud simultaneously? I mean that there is a 50% chance you'll get a star or a mega mushroom.

I do not think so. Main reason would be address conflicts. You would have to recode it to act in that manner.

I converted this code to C2 code to avoid using the Exception Vector Area.
