6 games to beat until the 90% mark.
Try for these 6?

Arkanoid - just have to wait until Saturday to get the supplies to finish Cheat Controller Mk 3
Athletic World - Easiest PP game for me to beat? Start doing 30 minutes of Power Pad practice a day to improve stamina
Flying Dragon - has passwords so I can at least make some progress and pick up later
Krusty's Fun House - another password game, just play along with the guide
Paperboy 2 - already at the 3rd stage w/ password
Star Soldier - Really close to finishing this, should get it in a couple attempts
