If i get it correctly, that's setting DISPCNT (0x0400,0000) register to use 32Kcolors-bitmap-mode, right?

then you fill the screen (VRAM @ 0x0600,0000) with some color i haven't decoded yet ...

and finally you enter an endless loop.

My! as i'm using libnds, i tend to skip most of those magic-number-things and have pre-defined nice names for every hardware bits either you need an excellent memory of numbers, or you need a bunch of #defines

You are right that what it does and color is red.
You may need to fill the logo and set check sum, but it work fine on my DS and GBA setup as is, but some say it needs the real logo ?.

jas2o has got this nds http://dsemu.org/The_Smallest_NDS.html
arm asm code, to assemble and run on his DS with FasmArm .

PS: I have also got fasmarm code runing on my GP2x.

hehe... there will always be guys to shrink data smaller than they should ever been (remind me of "how to make ELF/PE executable that suits 4K compos")

btw, i patched "desmume" so that it supports SuperCard-like storage (in an image file created following the OSFAQ, if you wonder), and i was surprised when it reported a PC in system RAM. For non-plumbers here, there is only 4MB of RAM on the nDS and your code typically execute from cartridge ROM (up to 32MB), so that sounds a bit weird to have code _there_ ...

Seems like i'll check my bootstrap code (the one from DarkFader, iirc) and see what it does ... or maybe the .ds.gba files behave differently ...
