What does the ちゃい in やっちゃい mean? I suppose it's not やっちゃう aka やってしまう...




やっちゃいねえ here is a combination shortened/colloquial version of やってはいない.

ない>ねえ is a change that happens frequently in colloquial masculine speech
(which this pretty obviously is, it's got おれ also).

やっちゃ is a shortening of やっては. You're generally allowed to put a topic particle
between the two halves of a -て+VERB construction (unless the verb is しまう).
