I am trying to get DS/DSi game forwarding using CIAs to work on my 3DS. I run the latest Luma and the most recent firmware [11.10.0-43] (see below, if you need any information on what I have done so far).

I followed this guide. However, installed CIAs appear as a blank rotating icon, which, when I press to start, lead to the following error screen:

"An error has occurred.
Press and hold the POWER button
to turn the system off.
Please refer to the Operations
Manual for details."

Does anyone know how to solve this?

Originally, I thought the problem revolved primarily around this process, which involves fixing TWL. However, as I said, although it has restored DS/DSi functionality for officially purchased DSiWare, and game cartridges, it does not allow me to run installed CIA forwarders for DS/DSi games. Original post follows:

I installed CFW (Luma - latest version) using the full process @ 3ds.hacks.guide which was successful on my 9.4.0-21E first-gen (ambassador edition) old 3DS. It works fine, and can install and run CIAs and homebrew as expected. 3DS games/software function correctly without any issues.

However, while trying to find a way to run DS/DSi software via CIA forwarding, I realized that this functionality is broken.

I understand that this is a common issue, as evident here and here [to mods: if any of these links is not allowed, please let me know and I will remove it]. The solution, on 3ds.hacks.guide, seems quite straightforward. However, I have read that the most recent firmware does affect CFW on European systems. I could not find any reports that clarify whether these guides can still be followed, after the recent firmware updates by Nintendo. I wouldn't want to lose CFW for this.

To make things worse, I followed only the first part of the 3ds.hacks.guide process, meaning I removed the broken TWL files using TWLFix-CFW. DS/DSi games were not running before, but now when I attempt to run them I get a more serious looking error that says:

"An error has occurred: Failed to mount CTRNAND. Press any button to shut down."

This to me sounds as if I have soft-bricked all DS/DSi functionality. (This is, as I understand, exactly what TWLFix-CFW does, so that's ok?)

I read through this but I was not sure if my case was the same or not, so I decided not to follow this guide. I also found this, which seems relevant, but again I do not want to touch anything until some one who knows can instruct me.

Hopefully someone can help me restore DS/DSi functionality, and also finally get forwarder CIA games to work. I am using my own game cartridge to rip the game from.


Edit: Went ahead and updated, and DS/DSi game functionality is partially restored. However, game DS/DSi game forwarding still does not work.

    @_Ruri_, they slip
  • _Ruri_ @ _Ruri_:
    Hm, it makes sense. Nothing else comes to my mind then :/ I guess you have to either make efforts finding the right screwdriver or just give up
  • Xdqwerty @ Xdqwerty:
    @_Ruri_, I'd rather give up
  • _Ruri_ @ _Ruri_:
    @Xdqwerty, I guess. No places that sell screwdrivers around?
  • Xdqwerty @ Xdqwerty:
    @_Ruri_, not that I remember
  • _Ruri_ @ _Ruri_:
    Oof. Maybe supermarkets sell them?
  • Xdqwerty @ Xdqwerty:
    @_Ruri_, mmaybe
  • _Ruri_ @ _Ruri_:
    They should be pretty common screwdrivers so there's a chance
  • _Ruri_ @ _Ruri_:
    Don't know about the tri-wing screwdrivers though
  • _Ruri_ @ _Ruri_:
    They're basically Nintendo exclusive from what I know so no chance you're gonna find them in random physical stores
  • _Ruri_ @ _Ruri_:
    The normal cross ones you could though so you can probably take out the back cover
  • Xdqwerty @ Xdqwerty:
    @_Ruri_, they don't seem to be tri wing screws
  • _Ruri_ @ _Ruri_:
    @Xdqwerty, You could have a chance to take out at least the back cover then

    Dunno about the insides though, never disassembled a 3ds
  • _Ruri_ @ _Ruri_:
    Try checking out the iFixit guides

  • _Ruri_ @ _Ruri_:
    Huh according to the iFixit guides it doesn't seem like you need tri wing screwdrivers to disassemble the insides
  • _Ruri_ @ _Ruri_:
    That's pretty good news

  • _Ruri_ @ _Ruri_:
    Rest are standard Philips screwdrivers
  • _Ruri_ @ _Ruri_:
    And various spudgers but you could make-do with other stuff no problem
  • _Ruri_ @ _Ruri_:
    What's the issue again?
  • Xdqwerty @ Xdqwerty:
    Brb gonna shower
  • _Ruri_ @ _Ruri_:
    Okay see you

    @Xdqwerty, Dunno if you'll read this but I finished reading the story, I love the humor lol, and the idea of an incompetent hero with a smart kid is really particular, haven't seen it around much. Their dynamic kinda reminds me of Manzai (https://en.wikipedia.org/wiki/Manzai) humor, pretty cool
