Thanks for the list.
It appears Canyon Bomber used paddle controllers which means the Fire button on the left paddle should activate joyright. I could easily add a toggle switch inside the controller for paddle support.
I had this game at one point but ended up selling it back as it's not that great, though I can always go back and pick up one of the five copies my local GameXChange has in stock. I actually thought my joystick was broke when I first played it, until I looked and it said "use with paddles" but even then rotating the dial didn't do anything.
Swoops is also mentioned on the list as well but Flappy (well at not the 2600 version), Wall Jump Ninja, and Jump VCS are missing. Wall Jump Ninja is an excellent game btw.
The reason why most single button games are post Y2k is due to the smartphone phenomenon. Touch screens are poorly suited to action games or arcade style gameplay but work surprisingly well if you treat the entire screen as a single giant button. So they made some time wasters like flappy bird for you to play while sitting on the crapper.
Activision's Barnstorming has deeper gameplay than say Flappy Bird and I suppose the game could be hacked to use a single button if the throttle was always on and the plane drifted down except when Fire is pressed (instead of up). However this new control change would require retuning the physics and possibly reworking the level design.
