How to re-map control buttons on DKC?

[Markfrizb]

I am wanting to change the button mapping for DKC1,2,3. I'd like to change the functions of button B to be button A and vice versa.

possible? guidance please?

Thanks!

You are trying to do this in software? My inclination is to say that it would be easier to build/hack a controller that would remap any of the buttons for you. A schematic for a controller is over here (if you want to do it from scratch): http://www.gamesx.com/controldata/nessnes.htm

If not, I'm not sure exactly how it would work, but you'd probably have to do something like (in a debugging emulator like the debugging version of SNES 9x):
wait for a read of $4218/$4219

Then there will probably be something like a mask to check a specific joypad button, you'll probably just have to switch which bit is getting masked when.

The issue may be that you'd have to check for all the instances. I am not sure how it would work in an "official game" but the B/A buttons work differently in different situations (ie when you ride different animal characters, or are in a menu for selecting your file...haven't played the DKC games in very long). The input may also be stored in different variables in RAM for different purposes (ie a momentary press, versus a hold). See bazz's sample code:

I think you are right, I'll go the hardware route.

No problem!

I'm surprised that there was never a third party controller like that (the times I needed to remap controllers in an options menu I usually felt underwhelmed by my choices).

Coincidentally, I took apart a third party SNES controller the other day and it seemed to have extra pads it would be easy connect wires to. Also the L and R buttons were a separate little board attached by wires so it would be pretty easy to hack that. This one was a Tomec. Looked kind of like this:

There was the Tyco Power Plug accessory that added macro features to an existing Super NES controller.

ha I think I actually still have one somewhere. I remember it being a bit underwhelming.

Not sure if you are working on this at the moment, but I had a day off and was messing around with stuff related to this thread. This is probably pretty noob stuff if your electronics knowledge is on point, but I haven't messed with TTL-type chips in a long time. Anyway I tried out this circuit I came across:

http://www.gamesx.com/controldata/nessnes.htm

and recreated it on a breadboard. It worked pretty well. Only thing was I had to sacrifice the plug from a third party SNES controller:

Hey,

I've made that circuit before. It works great! The reason why I asked the question of button remapping is that I make an adapter/interface to run a Snes (and NES) to jamma (arcade game cabinet). My arcade cabinets only have 3, sometimes 2 push buttons....so I was trying to get DK's buttons to be the same as mario world and some others......all within the constraints of the arcade cabinet button configurations.. A,B, and Y are my buttons 1,2 & 3. DKC uses button X (to swap kongs) and I don't have a 4th button on the cabinet. So this is why I was asking about the button swapping... To make the game conform to the ABY mapping. But I worked out my issues with some mux's. (yes, I know select swaps the kongs too)

Appreciate you thinking of me. . Thanks!!!!
