Homebrew Python Tools for 3DS

[Snailface]

Reformatted and used the latest ROP_Loader. Installs fine but exploit still crashes 3DS :|

Is it a grey screen crash or a dialog box reset crash?

Grey screen likely means it's a problem with your code. Dialog box might indicate a badly formatted SD card (one user isolated the problem as an emunand partition).

Getting a dialog box with "An error has occurred".

Getting a dialog box with "An error has occurred".

Try a different SD card.

 

[sonic2756]

Try a different SD card.

Did, same thing. Trying to open any DS game after running ROP_Loader gives me "An error has occured".

Sounds like your DS mode is bricked. You'll have to do a system format.

Did, multiple times. Running ROPLoader results in the same thing every time.

Do a system format & try again.

This is what I get while running ROPLoader. Everything seems to check out ok.

Just formatted and tried that. DS profile isn't corrupted but still can't get anything to launch.

Edit: DS games launch but this is what shows up after running a DS game. http://d.pr/i/x3Dc

Fill the entire screen with a solid color then write_word() over it.

What parameters do I fill it in with?

Sorry, its paint_word().
The parameters for all functions are spelled out in the memory.h file. Have a look at it.

Edit:
Made a little mandelbrot for fun. There is no input yet so I just have it cycle automatically.

Does anyone know what the address for the right framebuffer of the top lcd is?

Source is attached if you want to look at it.

This is great! How did you find the address for the numbers and other characters?

3 byte colors, 400*240 pixel screen

Spoiler

You can hard-code an array with a 8x8 font then code a function to draw it making use of the drawpixel (or whatever is called) function.

 

[nop90]

Attached you can find file with an ASCII-64 font.

Have fun.

This is like watching the birth of homebrew on the 3DS.

 

[Snailface]

This is great! How did you find the address for the numbers and other characters?

I put them in the letters.h file. I use my own addressing to find them.

Each inputed ascii char is 0-FF. That number is multiplied times 8 (in the memory.c file) to find the correct 8 byte sequence in the 2048 byte array in the letters.h header.

2048 / 8 == 256 ascii chars. And yes you can put an arbitrary .pf file array in the letters.h for custom fonts. I'll demo it later today.

Tried this today, stuck at "arm-none-eabi-gcc: error: source/*.c: Invalid argument".
