Requesting help finding software to run Python script on CFW Nintendo 3DS

[HardChibi]

Hi,

I installed CFW today and as such, have Luma3DS. With this 3DS I want to write and run a Python script that would open my Virtual Console Pokemon game and Soft Reset a shiny Lugia. I have previously written a script inspired by a certain public GitHub repo (I do not have enough reputation to share the link) on my PC that allowed me to Soft Reset on my PC emulator.

This is why I am asking whether there is a CFW app that I can install where I can write and run a Python script that would simulate button presses and take a screenshot of the screen to shiny check on the CFW 3DS. Any help is greatly appreciated.

If this is not the right place to ask this question, should I make a post for it?

Edit: I am aware that there exists an SR tool in PKMN NTR but I do not wish to download it as I have no desire to use any of its other features and not to mention it has features like downloading .pk* files. Furthermore, I do not wish to read the internal game data and check whether it is shiny but rather take a more "human approach".

There are ways you could do this, but it would involve using Luma3DS' Input Redirection combined with video streaming with NTR-CFW/HzMod and running the script on a PC. It would work very similarly to doing it in an emulator.
There is no app to run python scripts in the background. A NTR-CFW plugin or Luma3DS modification could do it, but would require C/C++ coding. It's not possible with normal homebrew.


I'm not sure why you want to do this on the 3DS though, when you could do it on a PC emulator and transfer the save onto the Virtual Console version afterwards, which would be easier and more convenient.

I hard-wired testpoints on my 3ds to a 8 port relay attached to a raspberry pi running python (with a lightsensor for the timing). Got all the ultrabeasts and legendary from ultrasun/moon shiny

I've heard of this method, I don't think a light sensor would work for Virtual Console games though.

For the switch I've got a cheap hdmi capturecard thing to replace the simple light sensor. A webcam on a raspberry will work absolutely fine, just read one pixel and adjust thresholds.

Thanks for the response! I am mainly doing this because this is the copy of the VC I bought and I have been SRing for this Lugia for years. I have roughly 14000 SRs done but nowadays if I SR for a longer period of time my fingers hurt and as such I am looking for a more automated option. I will look into the Input Redirection + NTR streaming you mentioned and see what I can do.

This sounds interesting! I am going to look into the method mentioned by @The Real Jdbye at first but I would love to look at your setup as well!

I tried Input Redirection and HzMod video streaming (mine is old 3DS) but it looks like you can't stream VC games. I will try using a webcam/ phone camera instead and see if I can get a good video feed.
