DS development > Is there a way to make Download Play Demos?

#115826 - Dox-999 - Fri Jan 19, 2007 12:01 pm

Hi I am not really a NDS developer but I am hoping of one day getting into it :) I was messing around with WMB and discovered that it dosn't play regular .nds files they have to be the speical .nds demo games. Is there a way to make regular .nds games and homebrew apps work over Download Play?

Thanks

First you have to flash your DS ROM or you could use a passme device. This allows the DS to run unsigned code. (official ROM's have some kind of encryption that gets overriden by the ROM hack).

After this:
As long as the NDS roms are below 4MB in size and if they don't require data to be on a storage medium like a slot1 or slot2 card(when such a card isn't present with that data on it), you can run that application through wifime.

ok thanks for this :) but how I "flash your DS ROM" ? I think I know what you mean but how do I go about doing it?

Thanks

Find FlashMe, make sure it's the real thing and the correct version (DS vs DS Lite), follow the instructions that should be on the page it's found on. I don't know if we're allowed to link it here since it's a hacked Nintendo ROM, but I don't remember the address anyway.

Official demos have a digital signature, which is essentially an encrypted hash of the file. Anyone can decrypt it but only Nintendo can encrypt it (or someone having their key, but to crack it would take hundreds of years), so there's no way to add the correct hash for homebrew or hacked ROMs. The standard firmware will reject those without a correct hash, but FlashMe won't. Assuming it either has the correct hash or you're using FlashMe, you can just send over any .nds file that's less than 4MB.

You can post at http://forum.gbadev.org/viewtopic.php?t=5718 to find someone in your region who will flash the DS for you.

Darkfader from the Netherlands was so kind to do mine :)
