When you press two of the three intellivision side buttons at the same time, it's equivalent to pressing all three buttons. The intellivision would have no way of knowing which two side buttons were pressed. Programs would have to be written specifically to handle this case. Defender is one cartridge that does so you can fire a missile and a smart bomb at the same time. Pinball is another but I'd probably play intellivision pinball with keypad buttons. Space Hawk, for example, does nothing when you press top and bottom side buttons at the same time.
The button arrangement described by tripletopper would be a bit awkward with pinball and tutankham. There's only a few cartridges where left and right side buttons are different, e.g. nova blast. The intellivision controller works best when left and right side buttons have the same function.
About Tutankham and pinball, I assume the Bottom left and bottom right are 2 different buttons, and left is left flipper/shoot left, and right is right flipper/shoot right. and i guess either top button (because you have a third button available) or BL+BR (because that's how they do it on Colecovision) is genie wish bomb.
The reason why I ask is because most modern games, when you flip to right handed, make the buttons flip horizontally, so that in Street Fighter, your light attacks are on your index finger, middles on middle finger, and heavies on ring finger, no matter which way you hold the stick. How does INTV deal with flipping? It doesn't, it assumes you use default controller, love it or hate it. :S
Would you say most INTV games have a concept of a left and right button or primary/secondary/tertiary?
The problem is if you use a fight stick, and you define the left stick as "normal" and have 3 buttons laid out (S T BL BR), then flipping it in the traditional would be : (BR BL T S), which makes left to fire right and right to fire left.
So it's kind of depends on what would be both the primary left stick fighting arrangement, and what would be the right. IF (S T BL BR) is normal for left handed, then is the right stick considered (BR BL T S) OR (BL BR T S)?
So more games uses a Left/Right model than a primary/secondary/tertiary model, i suppose. By the way on a P/S/T model, is the left button button considered secondary, or the right button, so is left clawing/ right d-padding considered the baseline normal, and the other an also ran?
Atari 5200 is a truly 2 button ambidextrous setup, there's a bottom button and a top button, but you have an index finger and thumb. Your index finger is always on the bottom button, and thumb is always on the top button, hence the bottom button is always the "main" button, and the top button is the "aux" button. Colecovision Super Action has a similar ambidextrous setup for 4 buttons.
But games with a definite left and right shouldn't be played with a Super Action Controller, like Tutankham, (Stick, Left Fire, Right Fire) vs (Right FIre, LEft FIre, Stick).
But then again, Front Line works right in a right handed setup: (Grenade/Board/Abandon tank, Rotate ACW, Rotate CW, Rifle/Tank fire Stick) works right right handed, but doesn't work right on a traditional left-stick setup: (Stick, Rifle/Tank fire, Rotate CW, Rotate ACW, Grenade/Board/Abandon Tank) Since you're going up mainly, CW is right and ACW is left... unless you "cover your 6", then it makes sense.
