Tried to catch the three jetpack changes, and think I got them. If not, the conversion made is here.
jetpack0(2) > jetpack(2)
jetpack1(2) > jetpack-on(2)
voidjetpack0(2) > jetpack-void(2)
voidjetpack1(2) > jetpack-void-on(2)
black_jetpack0(2) > jetpack-black(2)
black_jetpack1(2) > jetpack-black-on(2)
So black_jetpack12 becomes jetpack-black-on2.
