so, when attempting a run of this, I could not find pac-attack or pac-mania, are there pre-req's to unlocking those modes?

EDIT: did a search and found that I needed a score of 20K on pac-man for Pac-attack and 15K on ms. pac-man for Pac-mania. I was wondering if there should be 2 high score categories? one for completing the game normally (like I did without pac-attack and pac-mania) and have the current all high score setup as a sort of NG+ since you need standing scores on some in order to do the run.
