Yeah... That worked... Why?

well the issue has been narrowed down to lpp-3ds not knowing what folder it's in I guess.

with that, edit the index.lua file and put this in it instead:

Code:

Screen.waitVblankStart()
Screen.refresh()
Screen.debugPrint(5, 5, "CDir: "..System.currentDirectory(), Color.new(255, 255, 255), TOP_SCREEN)
Screen.debugPrint(5, 25, "B - Exit", Color.new(255, 255, 255), TOP_SCREEN)
Screen.flip()

repeat until Controls.check(Controls.read(), KEY_B)
System.exit()

It says that the current directory is the root. "/"
Weird.
Anyways, thank you so much for doing this.
I guess this is just some strange bug with lpp, since I can't think of anything else it might be.

Huh, it's nice that that lets you use lpp-3ds apps but I guess that means you can now only use one at a time until this gets fixed.

Can somebody tell me how to take multiple screenshots.I tried using this command

Code:

System.takeScreenshot("/file.bmp",false)

but this always deletes the older screenshot

try this:

function getTimeDateFormatted()
	local hr, mi, sc = System.getTime()
	local dw, dy, mp, yr = System.getDate()
	return yr.."-"..mp.."-"..dy.."_"..hr.."-"..mi.."-"..sc

What will be the command to zoom an image?

Is it possible to make the screen fade to black and then back to normal?

Yeah, just use the blending features for GPU textures, a sample on how it works can be found in CHMM2 sourcecode: https://github.com/Rinnegatamante/CHMM2/blob/master/source/index.lua#L443-L449 (It's the preview system).

Looks like the hblauncher you're using seems to not properly send homebrew directory to lpp-3ds.
Where your files are?

Use drawScaleImage or drawImageExtended

I'm using gridlauncher. It's the boot.3dsx on the root of the SD card, and my files are pretty much all in the 3ds folder except for that "gridlauncher" folder that comes with gridlauncher.

However, I'm also using the same version of gridlauncher on my O3DS, and lpp-3ds works just fine on it. So I don't think gridlauncher is the problem.
Just to be safe, I redownloaded the normal Homebrew Launcher and used it to launch instead, but I just got the same error, "Error: index.lua file not found"

A single program will work if I put all its files (other than its 3dsx) on the root, but that means I won't be able to use more than one program at a time.
What else could it possibly be? I know I've said this a few times, but the only abnormality my 3DS has compared to most people's is that it's Japanese.
All I can think of is getting another person with a Japanese N3DS to test it, and if it works for them, my 3DS clearly just doesn't like me.

So it can't be solved by me, i'm quite sure the problem will appear for any homebrew relying on setArgs of hblauncher to get hb folder.

For bottom screen, you're calling a termBlend right after a initBlend... it obviously print nothing.
For the keyboard, you should call it before flip+waitVblankStart.

Do you have any examples of other homebrew that use setArgs? Every homebrew I've downloaded so far has worked other than this, so I kind of want to know which ones won't and test them.
And wait... Then why did 3DSHangman work? Isn't it using lpp-3ds?

Alright, this is somewhat related to my problem with index.lua not being found, but I'm trying to compile the source code of lpp-3ds and I keep getting this

Code:

linking lpp-3ds-master.elf
c:/devkitpro/devkitarm/bin/../lib/gcc/arm-none-eabi/5.3.0/../../../../arm-none-e
abi/bin/ld.exe: cannot find 3dsx_crt0.o: No such file or directory
collect2.exe: error: ld returned 1 exit status
make[1]: *** [/c/Users/bobbin/Downloads/lpp-3ds-master/lpp-3ds-master.elf] Error
1
make: *** [build] Error 2

I tried Googling it and I can't find a mention of "3dsx_crt0" anywhere. I also couldn't find any referrals to it in the makefile or in main.cpp.
Is there a library I'm missing or something? I already downloaded Python.

EDIT: Nevermind, I found 3dsx_crt0.o in some folder in the devkitpro files and copied it over. Now it compiles.
