How to generate a Cracker launcher shot ?

[Dr.Party]

Hi,

I'm trying to spawn a "Cracker launcher shot" which is 0E for the "Dr.Mario over ike" port's neutral special (since Mario's fireball is very hard to port) but when I do the attack the game freezes, I tried to use the code from the  "ItemLauncherFire" subaction with no success,

Then I tried to generate the launcher (which is 0D) its self along with a subroutine  to "ItemLauncherFire" and then "consume" item 0D, hoping that he fires the gun once and then let it disappear  it but then he spawns the gun and  nothing happens,

So, can someone please tell me what i'm doing wrong with one of the two methods  ?

I've got the PAL game if it matters.
