Hey all.
I'd like to introduce to you, Tesla: My answer to the growing need for proper ingame front ends for sysmodules.

What is this?

• Tesla consists of three individual parts. nx-ovlloader, the Tesla menu and libtesla.
  • nx-ovlloader is basically nx-hbloader ported to run as a sysmodule. It runs in the background and loads overlay NROs (.ovl files) given to it.
  • Tesla Menu is the equivalent to the hbmenu. It's the initial thing loaded by nx-ovlloader and acts as a hub for you to select all other overlays.
  • libtesla is where it becomes interesting for developers. It's an easy to use library that handles layer creation, UI drawing and all the overlay UX. It makes it very easy to create a new overlay for anything
• A frontend for sysmodules that before required either a homebrew or a config file to change settings or used sounds or the LED to give the user feedback.

What is this not?

• A tool that lets you create overlays that are always visible. Overlays can get unloaded way to easily for this.
• An excuse to port absolutely everything to a overlay. Nobody's going to need a title manager overlay. If you consider making a overlay, keep it simple. You don't have a whole lot of memory to work with.

How do I use this?

First of all, download the latest release of nx-ovlloader and the Tesla Menu from the GitHub Release page and extract it onto your SD card.
After a reboot, hold down L and DPad Down and push on the right joy stick to bring up Tesla at any time. Navigation works as you imagine it.
Similar to normal homebrews, you place your .ovl files in the /switch/.overlays folder on your SD card.

Notice

Make sure to use the latest Atmosphere release when trying this as older versions ( as the one SX OS uses too ) probably won't have enough memory available for this to run. Overlays do take a lot of space so nx-ovlloader reserves 6MB. 2MB for framebuffers and around 4MB for overlay developers to use in their overlays.

Yes, I confirm the system error. Checked on Mario Odyssey. Launch Tesla overlay, select Edizon, select Cheat, Error. Experimentally, I found out that the system gives an error if the cheat code in the txt file is too large. Removing a large cheat code in txt file, leaving only one cheat in a txt file, it worked. Sorry for my bad English)

I dunno exactly how many lines it can handle, but big codes I break into 2 plus separate codes, no more than 60 lines to be sure
Example:
[Long code (part 1,60 lines)]

[Long code (part 2, 60 lines)]

[Repeat until done]

And enable all at once when I want to use that code

Since I updated my switch to 10.0.1 I can open the Tesla menu in the menu, but not if a game is launched, someone has the same issue or an idea how to fix it?

This is an issue that started happening in 10.0.0. Go under Settings -> TV Output and make sure that the display scaling is set to 100%. Anything else will cause the menu to not appear anymore in games.

Working on 10.0.2 ?

What files did you use? I downloaded the latest releases of the three and overwrote what was on the SD and the overlay doesn't appear even on the home screen

Uhm, make sure to delete atmosphere/contents/010000000007E51A folder when you updating. Hope it helps.

 

[haruka-cantabile]

Did you updated https://github.com/WerWolv/nx-ovlloader ?

I have. Updated the other two files as well, but did what Starhatred has advised and it worked again.

Uhm, make sure to delete atmosphere/contents/010000000007E51A folder when you updating. Hope it helps.

Thank you! Apparently that folder was what's making it not show up lol

1) what game?
2) try loading game, hitting home button (but don't quit!)
3) load overlay and enable cheats from home screen
4) exit overlay completely and go back into game

Give that a try

Game is Mario Odyssey. I tried to do everything as you advised. And still the error at step 3. When I try to open cheat list overlay is freeze.

Try deleting that inf health code or change the first line to 02100000

I just tried to leave only health, deleting everything else and it worked. In my case, the problem is in [purple coins]
