Attempting to use Network functions with the .3dsx build fails. It works on .cia and .3ds builds though.
A simple test I put together:

local WHITE = Color.new(255,255,255)
local pad = Controls.read()
local oldpad = pad
Screen.refresh()
Screen.clear(TOP_SCREEN)
Screen.clear(BOTTOM_SCREEN)
Screen.waitVblankStart()
Screen.flip()
Screen.debugPrint(5, 5, "Network: "..tostring(Network.isWifiEnabled()), WHITE, TOP_SCREEN)
while true do
    pad = Controls.read()
    if Controls.check(pad, KEY_A) and not Controls.check(oldpad, KEY_A) then
        System.exit()
    end
    oldpad = pad
end

This code is run in both .cia and .3dsx builds. The following results are achieved

Network.downloadFile and Network.requestString seem to be having similar problems.
Furthermore, I observed that Homebrew Launcher or Gridlauncher both show the Network as disabled after exiting the application.

I am using the lpp-3ds build 26b96a2

It will return nil no matter what. Either that or I'm just stupid. Here's an example:

    st1start, st1end = string.find(st,startst,stoffset)
    st2start, st2end = string.find(st,endst,stoffset)
    stringstloc = st1end + 1
    stringendloc = st2start - 1
    retstring = string.sub(st,stringstloc,stringendloc)
    return retstring
end

while true do
    Screen.waitVblankStart()
    Screen.refresh()
    pad = Controls.read()
    if (Controls.check(pad, KEY_Y) and pad ~= oldpad) then
        st = Network.requestString("http://galladeguy.x10host.com/3DS/test.txt")
        Screen.debugPrint(0,0,insidestring("[MY_NAME]","[/MY_NAME]",st,1),white,tscreen)
    end
    Screen.flip()
    oldpad = pad
end`

It should print GalladeGuy because that's what's in between [MY_NAME] and [/MY_NAME], but it returns nil instead and doesn't print anything. Is there something wrong with my code? Or is String.find just not working properly?

Trying to build lastest commit throws this error: c:/lpp-3ds-master/source/include/lua/lstate.h:144:21: error: 'STRCACHE_SIZE' undeclared here (not in a function)

• strcpy/strcat/sprintf should never be used directly with user-input.
• None of the gfx code does any range-checks for the input x/y parameters, hence arbitrary memory r/w relative to the used buffer.
• lpp-3ds uses lua integers for struct ptrs. Again, more arbitrary mem r/w. AFAICT this wouldn't be an issue if userdata was used instead: http://www.lua.org/pil/28.1.html

For PoCs for some of the affected functions see here: https://gist.github.com/yellows8/614a9c131ee2f3e4a78b

My System:
new 3DS, Europe, 10.0.1-27

Steps to reproduce the Issue:

1. Download https://gbatemp.net/threads/release-super-simple-calculator.399475/ (or any other HB)
2. Close the n3DS
3. Open it again

What should happen:
The app initializes itself again

What happens instead:

• blackscreen / no output
• input does not work (neither does start)
• to fix this state you have to completely hard-reset the 3DS

I'm working on a project in luaPP and I'm trying to make a CIA out of it, but I want to know how I can put it into a folder like this
PayloadUpdater/script.lua
but how would I do it?

In Citra, giving the cube.lua script a texture and trying to run it results in a White Screen. On the 3DS, LPP has issues figuring out where the texture is supposed to come from, and multiple different solutions like using System.currentDirectory().."/cube.png" did not work.

Even if Line 2's Variable is a correct path, LPP has trouble with the variable on line 83, saying that it doesnt exist.
If any of you here are still at all active and can figure out how to get this sample working on either 3DS or Citra or both, please let me know, because I have tried everything and it just does not budge.

When downloading a file via HTTP it freezes the program, and doesent download the file.

Code im using:

if (Controls.check(pad,KEY_A) ) then Network.downloadFile("http://example.com/example.zip","Example.zip"

Is there any way to download a file without it freezing the entire program?

Hey,

I'm trying to use your lua stuff to build a simple tool that installs a cia from network and launches it (a bit like the netloader thing i build for 3ds_hb_menu, but just over http because i don't want to touch sockets again...)

So far i got it to download the cia, install it, and exit back to homescreen where I can then launch my app, but I wonder if you could implement something to launch a specified title directly (it seems to be possible, at least DevMenu can do it)

Calling System.checkBuild() causes not enough memory.

I can't find a tutorial, and I really want to make a game using this library. I would have asked on the forums, but I can't find the button to make a new thread.

SDMC global variable returns nil

Using wav player as cia build corrupts the sound system, also after lpp is closed. (Using rxtools).
This happens on most recent commit, but not the previous.

Whenever i try to load a 3dsx with .cia version of lpp-3ds it will exit to the homemenu and display the error;-"An error has occured,forcing the software to close.The system will now restart."
I am on 10.7 reinand.Please help

Also the 3dsx does not have an xml file

I would suggest an update to lpp-3ds to make it compatible with newest DevKitARM. The app has problems compiling with it, (for example with time.h)

Romfs fails with 3dsx because it's not specifying a romfs directory to 3dsxtool. Here's an example how to do it:

https://github.com/devkitPro/3ds-examples/blob/master/romfs/Makefile#L126

System.listCIA() causes a crash, the app exits and the 3DS restarts.

function checkntr()
local cias = System.listCIA()
local v
local installed = false
local updated = true
local count = 0
if (System.doesFileExist(System.currentDirectory().."ntr/ntr.cia")) then
updated = false
end
for _ in pairs(cias) do count = count + 1 end
for v = 1, count, 1 do
if (cias[v].unique_id == 0x00b00000) then
installed = true
break
else
installed = false
end
end
return installed, updated
end

This script was working correctly before, not on lastest release.

47af2eb ends up giving a default request type of 0 which is invalid and always comes back as an error instead of a default GET (1)

Network.downloadFile("https://3ds.titlekeys.com/downloadenc/", "/encTitleKeys.bin")

Hello I have a problem which is probably something that is so easy to fix that it will make me look like a idiot ^^

Basically what happens is when I try to put the frame size and I set the resolution to 400x240, which is the resolution for the 3ds/2ds screen. Though when I put it the file it and do the rest of the things it want's me to do it says.

"Depreciated pixel format used, make sure you did set the right one" or something to that nature.

Pretty sure I'm just being stupid, but any help is appreciated.

Add support for Fasthax to achieve kernel11 access on firmwares > 10.7 and get access to more syscalls

Trying to connect to a https website (Socket.connect(www.dshack.org, 443, true)) fails with: "Error:[string"?"]:56: SSL connection failed."

Trying to connect to a SSL server randomly causes "Failed creating SSL context". This error persists until you reboot your console. (Tried both with der certificate and without, same result).
Code: http://pastebin.com/jCuH4vzb

EDIT: This was caused by not calling Socket.Term() in some code paths, causing too many soc sessions to get initialized.

3DS applications now need to be built with -mfloat-abi=hard in devkitARM,but all the lib is built with softfp(i guess).

When I try running this, I get the error of "index.lua file not found"

When I extract a .zip file to a certain directory, it gives no errors. However, the contents of the zip are not in that directory.

I've updated devkitarm, and I'm getting this error:

I just don't know what to do for it.

Whenever i try to load a .3DSX through lpp-3ds it comes out with two black screens.
I was just trying something out this morning and ran into this issue.
Help would greatly be appreciated!

System details:

• EU N3DS
• 11.2
• Soundhax entrypoint
• Latest version of lpp-3ds

Problem

Calling System.exit() causes the bottom screen to alternate between red and black, constantly happens until I force close it using L+R+Down+B (doing this sometimes causes a complete crash, meaning I have to reboot the whole system)

Is there any way to set a line of text to copy to the 3DS clipboard?
I'd love to do this but im not sure how..

When I run the attached CIA, loadfile fails with the error Function not implemented when called with a romfs:/ name.

Am I doing something wrong?

• An example of the failing call is loadfile('romfs:/p3600/init.lua')(). (The target file does exist.)
• System.doesFileExist returns false as well. (Once again, the file is there...)

case.zip (contains CIA and the contents of the romfs)

Whenever i try to compile it, it gives me a error saying cannot find 3dsx_crt0.o.Please help.

I'm not a native english user so my grammer maybe wrong.

This only seem to affect audio jack, not built-in speakers. Running lpp-3ds and then exiting, causes the audio output volume to low. (Tested on O3DS nonXL Luma a9lh) I can tell it's not because the script, because even showing "index.lua file not found" causes the bug.

Whenever i try to launch a .3DSX via lpp-3ds, it freezes the app, and doesent do anything past that point.

Update makerom.exe to lastest version to add lastest devkitarm support.

Hi,

Tried running "vid2bmov" but I get the following error message: "The application was unable to start coorectly (0xc000007b). Click OK to close the application."

I'm using a 64BIT system too.

1. Convert a mp4 h264 30fps video to jpgv via vid2jpgv
2. After temp extraction, jpgv compains that cygwin.exe is missing.
3. Get Video converted successfully message.
4. There is no output file.

Is cygwin needed for this?

The Script vid2jpgv.bat should be reworked, it contains no check about if the convert was successful for real or not. It just uses a predefined text string.

Sorry if this is a stupid question, but is it possible to access resources from the RomFS from a lpp3ds script?

Thanks for any help. Have a good one.

Essentially, my Corbenik CFW Updater has to unzip + write a ton of small files to the card. The unzipping takes a very, very long time, especially on the o3DS (I haven't tried it on the n3DS, but it could be faster since I set it to 804MHz).

Right now, all Network functions are blocking. Calling downloadFile makes the application looks like it stopped responding and there is no way to indicate that the System is still doing something to the user.
I suggest adding a callback function to Network.downloadFile and maybe Network.requestString too (although requestString usually doesn't block as long as big file downloads) that gets called so developers can use that to show a progress bar for example, or simply allow for some kind of animated indicator that the download is still going.

If possible, adding the currently downloaded size and the full size of the file in question as arguments of the callback.
Example:

Network.downloadFile("http://www.example.com/example.file", "/example.file",...., function(currentBytes, maxBytes)
   Screen.clearScreen(TOP_SCREEN)
   Screen.debugPrint(5,5,"Currently downloaded "..currentByte.."/"..maxBytes.." Bytes", Color.new(255,255,255), TOP_SCREEN)
end)
