    Would it be possible to ds download play a homebrew application over to a ds? Another question though that likely is no but, would it be possible to then have it wright data to nand and essentially have a really small amount of homebrew on that nand, like modding the system to have cfw that would boot straight to a menu to select homebrew on the nand memory? Either a, download play games don't have nand access or b, there just isn't enough space in nand to put pretty much anything.

    I don't know, I think that would mean coding a whole network system like DS DP. Or reverse engineering it.

    why would the network be needed? pardon the strange idea but I was thinking of using a modded 3ds with a9lh & luma cfw (pretty much the best set up) to run a homebrew application on there to send the data over, I know you can download play homebrew applications on 3ds.

    DS download play applications are signed. There is a custom firmware/firmware hack called flashme that dodges this signing. It is not impossible that you could find an exploit in a game using wifi/local to in turn trigger an exploit in something but flash carts are cheap and readily available, not to mention writing most DS firmwares requires you to short part of the motherboard.

    Beyond that there are custom firmwares other than flashme, the flashme author called loopy did a minimalist firmware, another is called creebome and the most useful being http://fwnitro.caitsith2.net/ . http://problemkaputt.de/gbatek.htm#dsfirmwareserialflashmemory has the various sizes for various models. It is not a lot, significantly lower than the download play files usually clock in at (basically every download play game I have ever pulled apart has been the full 4 megs with wall to wall compression).

    ehh, never mind, my ds is a gba sp at the moment since a while back little ones tried to shove stuff in the ds card slot and bent the pins -.- so it's not a big deal modding the ds, if anything since I started installing gba vc on my 2ds I never touch the thing unfortunately :/
