How do u know R5 holds the ammo?

also try this: do add r5, r0, #1 on the sub

this might work and add bullets instead of subtracting

Then that's not the right offset lol

when did it crash? While shooting?

The #1 in the subs to 0.

 

i'm pretty sure you dont use the right ARM code. Armv7 has diffrent ones, so uze the right one. Covered in tutorial.
