Great list :) I've been working on #43 (Dr. Mario) off and on for a little while - it's my favorite old NES puzzler, better than Tetris IMHO. My (very WIP) version is at http://mrdar.io - the single player version is working OK (except for buggy mobile controls), now I'm working on implementing multiplayer over websockets... It's a lot more challenging than expected, but I'm learning a ton.
