    With DS(i) mode hack, can we now DS roms on 3DS without flashcard?

    probably never.
    has something to do with ds games adressing specific adresses on the flashcarts that don't exist on sd.

    you'd have to patch any and all of these adress calls in a ds game manually to have a chance of making this work. and thats just... too much work

    There has been a kind of breakthrough. There is a possibility of loading DS roms with SD access through NTR CFW. It is still being worked on.

    but running a ds rom from sd and running a ds rom from a flashcart while accessing the sd are two very different things, aren't they?

    it still doesn't change the way ds roms try to communicate with a system

    Yes but if this works then it means you won't need a flashcard for loading DS roms. You'll be able to boot them using ntr cfw from the 3ds sd card.

    no, it does not. having access to the sd card has never been the problem with this. its that the roms themselves want to access original ds cart hardware. because that's how they've been coded to work

    all nitrohax does is access cheats from the sd card and apply them to the game in ds mode. but this is very far from making ds roms work from sd

    NTR CFW, Not Nitrohax.

    Can someone clarify what is currently possible and what the breakthrough has been? :D
    Mabye with a link for proof or something?

    It has something to do with demo download stations. We are not getting full DS games as cia but it has been done with demos I believe.

    Uh... I don't know where people are getting this from. NTR was discontinued ages ago. It is Nitrohax, a homebrew cheat alternative to hardware like the action replay.

    But you can't run ROMs with it, it's just for cheats. Right?

    Correct. My point was that anyone who's saying this has anything to do with NTR CFW is sorely mistaken.

    Probably never? Haha, I expect a method within the next two months. After all, pretty much everything except loading retail games themselves is possible now. Within the last two weeks, we have DS homebrew channel loading without a game card, AR Cheats without a game card and using a legit game, and SD reading in TWL mode.

    BY THE WAY: NTR IS THE DS's CODENAME.

    This has nothing to do with NTR CFW, even though it was also based off the DS codename.

    now this makes sence, the homebrew might not have the problem with specific adresses in the flashcards. would ean it's not that much interesting since it means we created a backdoor to something we could allready use the frontdoor for... homebrew can just be rebuild for 3ds, as long as there's source... ahwell nice to see there's still progress...

    yes, all of that may be true, but it still never gets you around the fact that DS retail games try to access specific addresses on the game carts hardware, even if they're started from sd card. its not dynamic. its hard coded. you start the game from sd card and the first thing it'll try to do is load slot1://somefileswhatever. only that, the files it wants to get are actually in sd://

    Ah, but it is possible. Assuming that you can patch TWL_FIRM or something. Remember that GBA games are similarly hardcoded, and yet AGB_FIRM has no trouble running them from NAND. Emulation and backwards compatibility can be used in conjunction with one another. The later models of PS3 that could run PS2 games used that trick to cut hardware costs.

    I'm not going to say that patching TWL_FIRM to be able to redirect a cartridge game's attempts to read and write from and to Slot1:\ to specific ROM and save files on SDMC:\ would be easy. But it is possible. Consider that you can run cheats using TWL_FIRM already. Think about what was done with the Wii's MIOS in the old days.

    Ahezard plans to start with hbmenu as a base for a new rom loader. hbmenu really only doesn't parse overlays right now so that's why retail games don't boot. Homebrew doesn't use overlays. :P

    But it's clean and stable and Ahezard decided not to use Wood3DS anymore for further work on this. He might reuse the patching system akmenu used though.

    Because of how busy he will be in September it's going to be awhile before he gets serious work into this. So yes there's a good chance we'll get DS games running from SD now. But it's still months away.
