A n x n map consists of 3 (n+2) x (n+2) arrays: int map, float height, and float alt. For all 3 arrays, array[0][k], array[n+1][k], array[k][0], and array[k][n+1] (the four edges of the array) are padded with 0's for internal reasons. map[p][q] contains the texture number + 1 of the block at (p, q) (so a block using texture 0 would have a 1 here). height[p][q] contains the height of the block at (i, j) (each block is 1x1xheight). alt[p][q] contains the altitude of the bottom of the block at (p, q). For a maze, height should be filled with 1's and alt should be filled with 0's.

Well, Ndless 2 is still in active development (I think), so you'll never know what ExtendeD and friends will come up with

Lol Yay bad hardware!

Wait, what exactly are we trying to do here?
We can already execute machine code on OS 1.1, and Ndless 2 is rumored to function on OS 1.7, so barring future downgrade protection, Ndless 2 will bring with it the ability to execute unsigned applications on all versions of the Nspire hardware.
Or are we trying to remove the downgrade protection from 2.1?
Or are we just brainstorming general discoveries?

Expected.

I mean from within a C program.

Does anyone know how to list the contents of a directory on the Nspire?

We should just port Linux.

How would one go about writing a program loader? Would it have to be written in ASM, or can it be written in C?

Well, the Makefile does say
ASFLAGS = -mcpu=arm7tdmi
GCCFLAGS = -mcpu=arm7tdmi

Excellent This should be stickied. Someday, this sub-forum will have many threads in it, and this tutorial will be hard to find.

Yes, that would be ray tracing. Real time ray tracing on an Nspire would be ridiculous.

I should probably allow the client program to turn various features on and off.

sprintf is part of the OS (at least it's defined in os.h).
scrollScreen() arguments:
scrollScreen(char* scrbuf, char* tmpbuf, int lines)
Scroll the screen buffer scrbuf up lines rows. tmpbuf is a temporary buffer of the same size as scrbuf used by the routine internally.

Glad to hear its working I should probably move the scroll functions to graphics.h.
