Could you add a way to read files as binary?

You can write a converter from hex value to binary value if you really need it. To read a file in hex values you can see ORGANIZ3D or Sunshell Filebrowser sourcecode for the Hex Viewer ( https://github.com/Rinnegatamante/Sunshell/blob/master/LUA/modules/fb.lua#L549-L581 + https://github.com/Rinnegatamante/Sunshell/blob/master/LUA/modules/fb.lua#L592-L607)

Thanks, I didn't know about string.byte. Most other lua implementations I've used have a native way to read binary files.

Pretty strange issue, if you only need latest commits, you can grab a build up-to-date here: https://github.com/Rinnegatamante/Lua-RayCast3D

Hi there! This interpreter is awesome, but I'm running into a couple of problems with some of the System functions. For me it seems that System.launch3DSX() doesn't work. My homebrew just hangs when I call it and I have to do a soft reset to the homebrew launcher to get out of it. System.exit() also doesn't seem to work, it begins the exiting process and the bottom screen flashes red, but then instead of booting to the HBL it just continues flashing red then black then red then black. During this time I can soft reboot (hold bumpers + down + B) to properly boot back into the HBL but it seems the System.exit() function itself isn't working, at least on my 3DS. Any help I could get with these issues would be greatly appreciated! I'm using a N3DS XL and the latest Menuhax on 10.3. Thanks for the awesome app!

this has been solved in newer commits. it was an issue with *hax 2.x changing how it launches 3DSX files. if you would like, I can compile the latest commit for you.

this only happens with mashers's grid launcher. it might be related to sound, I think.

That would be amazing, thank you! I'm running Windows so compiling these things is a bit over my head.

Ah that's fine! I was just worrying it would affect my users, idm it myself. Thanks for the reply

and as if by magic, a built 3dsx appeared.

just for posterity: based on a34b5bf

Thank you, that fixed it!

@ihaveamac I wanted to take a few screenshots of the homebrew app I made with lpp, but it seems like the standard Home button shortcut to take a screenshot doesn't work. Would you happen to know of any easy way to do it?

lpp-3ds handles the home button so you can use it in a script somehow.

an easy workaround is to add something like this to your script:

if Controls.check(Controls.read(), KEY_Y) then
    System.takeScreenshot(System.currentDirectory().."/screenshot.bmp")
end

Or, couldn't you just use KEY_HOME instead of KEY_Y? To make it more like the *hax 2.5 payload's screenshots.
Or is the home button only usable in the CIA build(s)?

When I try to load an image iit gives me the error "attempt to access wrong memory block"

and this is what I wrote that gave me this error

Screen.drawImage(0,0,background,TOP_SCREEN)

background appears to not be an image for CPU rendering system. (loaded with Screen.loadImage)

Ok I named my bmp file wrong. Is it possible to make it that if you touch an image on the touch screen it controls something?

Yeah, just check touchscreen coordinates with the image coordinates (Controls.readTouch())
