Renders a malformed sprite on pressing z and the sprite doesn't get cleared

image

the keypad layout seems to be messed up as well, pressing x chooses rock and pressing c chooses paper (expected z to choose rock and x to choose paper)

Fixed. It seems like a bug in instruction 8xy5 or 8xy7 (or both), the flag register was being set incorrectly
