EDIT: holy crap I'm dumber than I thought. 3 button works. My 3rd button wire was not making a connection. I know somewhere I read naomi ikaruga doesn't work with 3 buttons but I have to assume that person was just looking in the service menu and didn't bother trying it. crazy.
I guess I'll change this thread to a real problem I'm having. Getting my Blast city monitor running in 640x480. I'll post the model # of my monitor and what I have tried so far.
below is some nonsense, now I have no reason to wire up my circuit. maybe i'll find another use for it. I could wire it up to connect to a nes to have A, B, or A+B for fun. but then it wouldn't need to be like this using the NC connection to provide ground to the other buttons. what made me think of this circuit was wiring up a joystick and 9 button setup for commodore/amiga. the idea being one button in the middle for fire then the 8 outer buttons were fire + a direction. the issue was if i left the joystick active it didn't work as expected. for instance if you are holding left then press the fire+up button it would fire diagonally. so i figured a way using diodes and normally closed so when you pressed a fire+direction button it also disconnected the joystick ground I think. practical use for this is easily executing all the functions in games that used lots of directions+fire and being able to do things like run left then quickly fire in an opposite direction then keep running left. useful in archon for example.
I was not sure where to post this. I suppose here. This is dumb and my a result of my lack of research. I designed a 3 button ikaruga panel and had https://www.arcade-projects.com/members/rbtamanini.2056/ make it. It’s great but what I didn’t check was of the arcade game even supports a 3 button option. The Dreamcast version does. The nesica version does I think. I’m assuming the GameCube version does. Unfortunately the original Naomi version does not. So I get art, this custom panel, a naomi and a cart version of ikaruga, I assume some horse racing game was sacrificed and I spend a lot of time trying to get one of my blast city cabs running in 640x480 but no luck I can’t get it to run above standard resolution. Then I finally realize the game doesn’t support 3 buttons. So I’m two steps away from the vision. I’ve always wanted this game in a cab running at the right resolution. For now I’m just trying to get the 3 buttons working and here is my idea. For the 3rd button I will try a 3 terminal button with normally open and normally closed. For fire and change polarity I’ll use the usual Japanese style two terminal buttons. Here is my diagram. I will admit I am not that knowledgeable with circuits, but it looks like it might work. What do you guys think? I’ll give it a shot. The theory is fire and change polarity will work as usual then when I press the special (release power) button it will first disable the other two buttons then engage fire and reverse polarity at the same time engaging the special attack, but I can’t really say what the game will do until I try it. Here is my diagram and the cab and panel.
