Im getting a scary error when i try to build from source.

Spoiler: error code

Go in devkitPro\devkitARM\arm-none-eabi\lib and do a "make CRT=3dsx"

ah thanks man that has got it to build. thank you.

also with the new payload functions are they on the documentation? or will i have to use the code you committed to find the functions I need to call?

Not in documentation but it's pretty easy to understand how to use.

Have i got the right idea in thinking that i need to have brahma.init() at the top of my code, to have everything related to payloads working. and then when i want to load arm9 stuff i need to have

arm9.start()
--arm9 stuff goes here
arm9.end()

and also somewhere i need to load.arm9.payload.offset (char *code.bin, u32 0x12000, u32 0)
and use launchPayload to load the rxtools code.bin right?

also does anybody have an app they have made which uses brahma i can look at to get the right idea here?

thank you

That is the C function, not the LUA ones.
This is the lua function: https://github.com/Rinnegatamante/lpp-3ds/blob/master/source/luaSystem.cpp#L1740
And these the arguments type: https://github.com/Rinnegatamante/lpp-3ds/blob/master/source/luaSystem.cpp#L1344-L1345

Whenever i load a .3dsx with System.launch3DSX()
I get two black screens.. Am i doing something wrong? @Rinnegatamante

I have a similar problem, i can load and boot minipasta.3dsx just fine, but loading cakes.3dsx and rxtools.3dsx gives black screens and wont boot, (using both arm9 payloads and 3dsx loader gives black screen as well).
i think its something to do with how they boot on the system and there is a timing issue here, if you can add a delay like you can with ctr boot manager maybe it can be fixed?

 

[Tech Freek]

I tried it with A test homebrew i made, and @TheCruel 's "Draw Attack". Neither of which worked.

yea it does depend, as i just tried booting back to homebrew launcher by pressing A with my app and it worked just fine

here is my code if anyone wants to see

Graphics.init()

-- Main Loop

if (Controls.check(pad,KEY_SELECT)) then

If an homebrew uses an xml descriptor, then it won't boot properly. current launch3DSX is just a minimalist bootloader.

I'm still havkng problems with sound playing, when I try to play an streamed ogg, it loops at second 5 or 6

Post your code. Also are you using csnd or dsp?

 

[PabloMK7]

Post your code. Also are you using csnd or dsp?

bgm = Sound.openOgg(System.currentDirectory().."resources/bgm.ogg", true)
Sound.init ()
Sound.play (bgm,LOOP)
while true do
--Some other things
end

I'm using Sound.play, so I don't know which service I'm using.
Ask me if you want the full script.

If you don't have an XML with CSND, you're using experimental DSP which is unperfect.
Anyway you're not calling Sound.updateStream in your main loop so it obviously loop only initial part.

Added Sound.updateStream () to main loop, but now crashes after a few seconds. (Using cia build)

Is your script fast to execute? updateStream need to be called like every 2-3 secs.

It is, I added it at the start of the main loop.

Post the entire script if you can.
