it, and so the finding-must be affirmed. Likewise we must sustain the hearing court’s finding that the plea was knowingly and intelligently entered, a finding not vigorously disputed in this appeal. Further, since the confession has not been shown to have been improperly obtained, we need not consider whether it primarily motivated the plea. Appellant’s final contention is that he was denied his right to appeal. Appellant was found guilty of first degree murder after a plea of guilty to murder generally, and hence the denial of his right to appeal would be prejudicial, there being the possibility of non-constitutional errors in his degree of guilt hearing. See, e.g., Commonwealth v. Zaffina, 432 Pa. 435, 248 A. 2d 5 (1968) ; cf. Commonwealth v. Walters, 431 Pa. 74, 244 A. 2d 757 (1968) (<HOLDING>). This claim was raised in appellant’s
holding that where both firstdegree and felony murder were possible bases for a murder conviction a jury instruction that suggested the jury could rely on felony murder as the predicate offense for a conviction for conspiracy to commit murder was improper because under arizona law a conviction for conspiracy to commit firstdegree murder requires a specific intent to kill holding that indictment for murder in the first degree charges murder by whatever means it may have been committed regardless of the theory of murder presented to the grand jury holding different rule applicable for conviction of second degree murder holding that defendants conviction    must be vacated where defendant argued that trial court committed plain error in instructing jury on nonexistent crime of attempted second degree murder holding that there are no lesser included offenses of second degree felony murder because of the multiple means of committing the offense
