Tutorial How to make 3DS Games with Unity

[grisu_YT]

You still have the banner problem?

no but armcc error

Could someone tell me the steps on how to set up unity for 3ds from archive.org or somewhere else? and also is there some kind of documentation somewhere for this?

Its work on Old 3DS ?

Reading OP under target platform seems to state you can build for old models. ya just got less resources to work with.

Hey, so I'm glad to see this thread is still active.

I'm trying to build a super simple game for the 3DS (this issue appears on both the n3DS and o3DS through Citra. On my physical o3DS, it shows the Nintendo logo then crashes - stack trace posted several posts down).

The top screen is being duplicated with a slight offset to the bottom screen. In unity, each camera's target is different and in unity, it renders properly.
This is what I expect:


This is what I'm getting (note: cube's rotation is intentional):


Does anyone know what could be causing this and how to fix it?

Just set the lower camera culling mask to something different from the upper because the upper camera will duplicate the lower one if you don't do this

Wow, thanks! That made the lower screen stop duplicating the top, however a UI sprite that should be showing up on the bottom screen is not.

Expected:

Try different shaders. Best way to do so fast is to create 5 buttons or so, and see which one shows up when you build. Make them differently colored or something so you know which shader worked. Are you able to build or this is all on unitys editor

I am able to build. Play mode doesn't accurately show what would happen on the device.
Speaking of which, I am only able to run the apps in Citra. If I try running through my homebrewed 3ds, it crashes with errors every time (stack trace posted several posts below).
I will try your suggestion to play with shaders, thanks!

I can't figure out a good shader to use with UI elements - I can get the text and button to show up using `Mobile/Particles/Alpha Blended` yet I can't change the color properly.
Not only that, but the button does not seem to be properly clickable in Citra (I still cannot get it working error-free on my physical device).
I also tried using OnGUI and even Nintendo's own KeyboardExample scene, yet it crashes when Unity tries creating a GUI button.

the UI shaders dont work? i wouldnt use a particle shader for UI i didnt have issues rendering UI on my app

If I use no material for the UI elements, they don't show up. I'm at a loss here.

how about the UI shaders? or some of the unlit ones. Alpha blended is for transparency. While it should be renderable, you could maybe use some other simpler shader

I'm pretty sure those don't show up or don't look proper. I will try again and post results. Thanks for your help!

Maybe you could set up the bottom camera to only render UI elements, worst case scenario it saves you some processing.
Oh and give the background's material a lower render queque (or was it higher?) so you make 100% sure it's rendered below the buttons and not on top of them.

The bottom camera's culling mask IS only set to UI.
As for the background - there actual is none, the camera is just set to Single Color
