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.

Spoiler: Screenshots

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.

Thanks a lot and have fun using and extending it

So by implementing this to tmemClose()

         if (t->src_addr != NULL) {
+            MemoryInfo m = {0};
+            u32 p = 0;
+            while (m.perm == Perm_None) {
+                svcQueryMemory(&m, &p, (u64)(t->src_addr));
+                svcSleepThread(1000000);
+            }
             __libnx_free(t->src_addr);
         }

I have solved issue without using shenanigans I have implemented into libtesla. Though it will require PR to libnx and then manually compiling libnx to get it right until new libnx release will come. I am trying to see if I can push in this form into main libnx fork or I need to change something, for now my libnx fork is here:
https://github.com/masagrator/libnx/tree/patch-1

Thanks to SciresM for proposing idea to solve this.

if your overlays are not showing at all you must look if your tesla is the latest and your Tesla-Menu (ovlmenu) https://github.com/WerWolv/Tesla-Menu are up to date.

I made sure to delete everything and start from scratch, and it is still not working. Not sure what the problem could be. I even tried with three different controllers and I know they have functioning L, DPad down, and right joystick click buttons.

 

[masagrator]

Well, here is PR.
https://github.com/switchbrew/libnx/pull/606

After accepting it I guess I will send PR to libtesla to revert last commit

 

[ELY_M]

I added the PR to libnx and built and installed libnx then rebuilt everything and installed.
Did testing. it still crashing in pokemon violet.

hmm...I used 20+ times in pokemon scarlet and many times in other games didn't crash for me, docked mode

 

[Runtuntbadunt]

So I figured out my problem (the button combo was different and I didn't know, lol) but now when I try to use sys-clk the console crashes and gives me "Error Code: 2001-0123 (0xf601)." Is sys-clk not updated to work on the newest version of tesla or something?

Oki. So when pr become merge anither night building all my overlays for now primary console still on 15.0.1

Checked your report and video on github and your issue is unrelated to my PR.

First of all you're only hiding overlay while this bug happens exclusively when exiting overlay.
And unlike in this bug, you got 0x2A8 (Prefetch abort) instead of 0x4A8 (Data Abort).

For this even fix with changing sleep to 50ms wouldn't help as it's never executed.

hey @All. If i start my edizon, no cheats loaded, what do i wrong?
Have HOE 16 and the latest atmosphere

it could mean that the cheat file is not found, check your cheat file path and build id

 

[Hando-Redneck]

it could mean that the cheat file is not found, check your cheat file path and build cheats are in contents. And i downloaded all cheats before with all i o updater.

 

[ELY_M]

I admit that I am lazy about closing overlay all way.



yes, simply hiding and unhiding overlay do cause crashes........

I have to fully exit the overlay by pressing the B button 2 or 3 times.
I did few tests this way and I have not got any crashes if I exit fully each time.

So this needs to get pushed to libnx, then libtesla and then to all the different overlays?
Is that the correct path?

Still waiting to upgrade to FW 16.

official path. This can be implemented already by anybody that knows how to compile stuff.

 

[[Truth]]

official path. This can be implemented already by anybody that knows how to compile stuff.

Let´s hope we get official releases till TotK release then.

 

[dsrules]

not all games has cheats, try different games or use edizon se and see if it could detect any cheats

 

[ELY_M]

you have to recompile ovlloader with latest libnx with PR from @masagrator and all overlays need to be recompiled too.

I was able to avoid crashes now.

you can git clone https://github.com/ELY3M/libnx
then cd libnx and make and make install
