Downgrading, Setting up Custom Firmware + arm9loaderhax

Can I downgrade from 11.0.0-33?

You can use a console with custom firmware set up to use DSiWare exploits and use System Transfer to use it to downgrade a 11.0.0-33 system. https://github.com/Plailect/Guide/wiki/DSiWare-Downgrade

You can also get a hardmod for your device. Don't update to any future firmwares, as they will prevent any chances of downgrading until we get new ARM11 + ARM9 exploits.

Then, follow the "hardmod downgrade". https://github.com/Plailect/Guide/wiki/Hardmod-Downgrade

There are currently no software-only solutions besides DSiWare.

Can I use ROMs through the Homebrew Launcher?

No, downgrade and install CIAs.

Should I use rxTools? Why should I switch from rxTools? What about dukesrg's fork?

rxTools's custom firmware portion (rxMode) is not actively maintained anymore. Any future update can prevent rxMode from booting since it's using older firmware. dukesrg isn't currently maintaining the rxMode portion, so it will stop working properly as well.

See this link for more information: https://gbatemp.net/entry/rxtools-why-should-you-stop-using-it-and-what-can-you-do.11313/

If I change custom firmwares, will I lose my games/saves/etc?

No, everything will stay.

I found this video guide to help set up cfw/a9lh...

Don't use video guides. They usually get outdated quickly and are hard to update. For custom firmware and arm9loaderhax, Plailect's guide is the go-to one for everything. Read all of it. It will bring you eternal youth and happiness. https://github.com/Plailect/Guide/wiki

Is a 4GB SD card good enough for following Plailect's guide?

Technically yes but it's not a good size for long-term use. You should consider getting a larger card.

How do I move files to a new SD card properly?

If you are using arm9loaderhax + updated SysNAND, you can simply copy your files over. If it's above 32GB, you'll need to format it with EmuNAND9 first.

When I turn on my 3DS, the power light just turns on and off!

arm9loaderhax is working as intended (you're not bricked!), but you don't have an SD card or you don't have arm9loaderhax.bin.

Why should I use custom firmware if I already have Gateway?

You don't need to move from Gateway if you already have the card. Feel free to keep using it all you want.

Gateway has their own a9lh. Should I use it?

No, Gateway's arm9loaderhax implementation is unsafe, ties your console to your Gateway card, doesn't let you boot other payloads (Decrypt9, etc.), and in general is not recommended by anyone. https://gbatemp.net/entry/psa-dont-use-gateways-arm9loaderhax-installation-tools.11242/

If you want to use Gateway mode with arm9loaderhax, use this guide.

Should I buy a Gateway/Sky3DS card?

No, waste of money. You can do everything with free custom firmware. Use Plailect's guide for that. https://github.com/Plailect/Guide/

Playing Games, Using Custom Firmware

Will Nintendo ban me for using cfw/pirated games/etc?

No, they won't. They probably can't detect it properly either without accidentally banning some legitimate users either.

Note that using ROMs on Gateway/Sky3DS requires private headers to safely play online. If you use public headers you can be temporarily banned. CIA/digital games don't have this issue.

Why is Decrypt9/EmuNAND9/etc exiting back to Homebrew Launcher?

• If you're using arm9loaderhax, you should use the .bin payload (e.g. ) through arm9loaderhax with some chainloader (e.g. Luma3DS).
• If you're not using arm9loaderhax, make sure you're running it from a 9.2.0-20 or lower SysNAND.

Why am I getting 022-2452 when trying to use the eShop?

Turn off dev UNITINFO patches. Or stop using things like Luma3DS dev version.

Can I transfer to/from a 3DS to one with cfw?

Yes, the transfer will work just as fine. Illegitimate tickets (homebrew CIAs, Illegitimate games, etc) will be lost, so you should re-install game tickets and homebrew CIAs after the transfer. You should save your Home Menu layout before transferring to save time re-organizing Home Menu icons.

Can I use .3ds ROMs with cfw?

No, convert them to CIA. 3dsconv is the easiest method for doing that. If the ROMs are encrypted, you should decrypt them first or generate XORpads.

How can I play GBA games?

Use 3DS Simple GBA Converter. Don't bother patching AGB_FIRM, Luma3DS does this for you.

If you're still using Emu/RedNAND, you'll have to install GBA CIAs to both SysNAND and Emu/RedNAND.

How can I play DS games on 3DS? What is a good flashcart for DS games?

Get a flash cart. DSTT is a good choice that works with DS game forwarders and is pretty cheap.

Why can't the 3DS run DS games without a flashcart?

Because we can't just redirect reads/writes to the SD card. TWL_FIRM does basically nothing; DS games run "bare metal" on ARM9 and directly communicate with the game card. If TWL_FIRM handled reads/writes, we could redirect them easily.

But there's a DeSmuME port!

That's an emulator, not exactly native. It's still a work in progress, and New3DS only for the most part.

Why is my DLC/custom themes I installed as CIA getting deleted?

Illegit DLC (DLC you don't own) can sometimes get deleted when you open the eShop or any DLC shop.

How do I dump my DSP firmware for use with Retroarch/CHMM2/etc.? (dspfirm.cdc)

Use DSP Dump. Just run this at Homebrew Launcher once. https://github.com/Cruel/DspDump/releases/download/1.0/DspDump.3dsx

BootNTR is giving me "firmware not supported"!

Make sure you're using the 11.0 FIRM (for Luma3DS, make sure there's no firmware.bin in ""), and use this one instead: https://github.com/astronautlevel2/BootNTR/releases/download/3.3.1/BootNTR.cia

BootNTR is crashing!

If you're using Luma3DS, use the latest version.

Why can't I import my game card save into my CIA/digital one?

You need to start the CIA version at least once before you can import the save.

How do I use out-of-region DLC? How can I use region/language emulation?

If you're using Luma3DS, check out its wiki on how to do this. https://github.com/AuroraWright/Luma3DS/wiki/Options-and-usage

• Enable region/language emulation: Enables the region/language emulation feature. This allows some games which need a specific language to be set to work, and DLCs for foreign games to load.
  • To use it:
    • Create a folder named locales inside luma/
    • Create a .txt file with game's title id as the name (look them up on www.3dsdb.com).
    • Inside the file,
      • Put 3 characters for the region ("JPN", "USA", "EUR", "AUS", "CHN", "KOR", "TWN")
      • Put an empty space
      • Put 2 characters for the language ("JP", "EN", "FR", "DE", "IT", "ES", "ZH", "KO", "NL", "PT", "RU", "TW").
  • For example, to play Pokémon™ Y in Japanese language and region:
    • Create
    • Put in
    • Save

Miscellaneous

I just crashed a game! Exploitable?

tl;dr Probably not.

Here's a more detailed explanation from topkeknosnek...

A crash does not equate to an exploit. From a gravely oversimplified view, exploitable bugs are a subset of all bugs. Crashing can happen due to circumstances completely useless for exploitation, mainly if the game's programming is just shoddy and can't handle a certain corner case.

Without going too deep or technical into the details, exploitable bugs require a certain amount of user-provided data that can be put into place in order to be executed. While QR codes provide a convenient means for providing large amounts of user-controlled data, but it may be properly validated so that no exploits are possible.

Why are 3D shacks allowed?

Because /u/dequo said so. And there's nothing that can be done about it right now.
