v6.5

• Full CTRNAND support: if the SD card is missing, you can boot Luma from CTRNAND with a compatible A9LH install. On CTRNAND, the luma folder is located in /rw and can be managed with tools like FBI and GodMode9. The EmuNAND options will also be automatically hidden.
• Added safety checks everywhere throughout Luma when possible, this also includes FIRM patching (if any patch fails, Luma will either display the amount of failed patches or shutdown).
• Made the exception dump parser output the disassembly of the dumped code where possible.
• Kernel9 patches patterns are now only looked for in Kernel9 itself (might speedup the patching slightly).
• AGB and TWL FIRM from 3.0 onwards are now supported (instead of just the latest versions).
• Fixed the anti-anti-downgrading patch on 11.2 FIRM.
• Removed the eShop update check patch as it caused more problems than it solved, and the background updates patch as it didn't work at all.
• Allowed using the FIRM of SysNAND with EmuNAND and vice-versa (booting with R) if not using A9LH.
• Fixed bug that made it impossible to print to the screen after FIRM was loaded.
• Fixed some files in the FIRM folders being incorrectly detected as FIRMs.
• Major cleanup/minor bug fixing/refactoring of the code, removed several assumptions and switched to structs where possible.

Please note that starting with this release, Luma won't support pre-patched FIRMs or other system titles with the same patches Luma does. Common pre-patched titles include NS, Home Menu, TWL_FIRM and AGB_FIRM (in these cases you will either get a svcBreak in loader or a shutdown when launching DS/GBA games). Clean versions of these titles need to be reinstalled before upgrading (the wiki will be updated with a walkthrough soon™).

v6.3.1

• Increased the maximum custom path size to 55 characters from 37.
• The Luma3DS.dat file isn't needed anymore with the new .3dsx (*hax, menuhax) launchers, arm9loaderhax.bin (or the filename specified with the custom payload path) will be loaded directly.
• Replaced the top screen image in the .nds file.

Reuploaded because people reported the CakeBrah .3dsx launchers wrongly displaying the .dat filename when arm9loaderhax.bin was not found, Luma3DS itself was not updated.

v6.3

• Merged the regular and dev builds into one.
• Custom version changes: if the custom version has more than 5 but less than 19 characters it will be truncated to avoid System Settings crashes; separated the custom versions for each NAND (the paths are now /luma/customversion_sys.txt, /luma/customversion_emu.txt, /luma/customversion_emu2.txt. /luma/customversion_emu3.txt. /luma/customversion_emu4.txt).
• To reduce file accesses for people with high-latency large SD cards, an option to toggle loading firmware.bins and FIRM sysmodules from the SD card and one to toggle loading the splash screens were added.
• External FIRMs support changes: added support for NUS-encrypted firmware.bins (all four are supported, a matching cetk file for each encrypted FIRM is needed: /luma/cetk for /luma/firmware.bin, /luma/cetk_twl for /luma/firmware_twl.bin, /luma/cetk_agb for /luma/firmware_agb.bin. /luma/cetk_safe for /luma/firmware_safe.bin) and New 3DS ARM9bin-decrypted firmware.bins.
• Turned the .dat file into a simple chainloader that loads arm9loaderhax.bin, added .nds file to use it with mset.
• The path changer is now deprecated (although it will still work). To have a custom path you can now enable the option for it in the configuration and type it in a /luma/path.txt file, it must start with a /. This path is also picked up by the above mentioned .dat chainloader.
• A full format of the SD card is no longer necessary to remove an EmuNAND (also fixes crashes when trying to boot EmuNAND with an SD which used to have one and wasn't fully formatted).
• The splash screens now display all at once thanks to the alternate framebuffer support.
• Fixed screen weirdnesses when not launching from arm9loaderhax.
• Added support for text files with a trailing newline (as per UNIX convention) for region/language emulation and custom versions.
• Fixed loading SafeA9LHInstaller and other payloads which need the OTP hash if having a PIN.
• Slightly changed the PIN format.
• Made option descriptions more readable.
• Fixed non-working double newlines in PIN messages.
• Fixed hangs on errors after a firmlaunch, reboots now happen as expected.
• bin2c is no longer needed to compile.

Reuploaded to fix a confusing typo in the config

v6.2.3

Both versions:

• Finally fixed GW-downgraded O3DS(XL) NANDs.

v6.2.2

Both versions:

• If Autoboot SysNAND was unchecked, it became impossible to select the EmuNAND if having a corresponding directional pad payload. Now it's possible to do this by holding A + the directional pad button.
• Added UTF-8 support to customversion.txt. You can now use symbols, including those special Nintendo font ones :P

v6.2.2: Fixed question marks at the beginning of the custom strings with files created by Windows Notepad.

v6.2

Both versions:

• Revamped EmuNAND support: up to four EmuNANDs are now supported, the default can be selected in the config and it can be changed on boot by holding Up/Right/Down/Left (respectively for EmuNAND 1/2/3/4); other than the legacy layout the minsize layout (for RedNANDs only) and the default layout are now also supported
• Added a B payload (b_NAME.bin) to the chainloader
• PIN changes: the number of digits to input is now shown, a message on the bottom screen can be displayed by placing a text file named pinmessage.txt in luma (800 characters maximum)
• Implemented custom System Settings Ver. string, it needs to be in a text file named customversion.txt (19 characters maximum) in luma, with the stock Nintendo string being Ver. %d.%d.%d-%d%ls
• When booting with R and the Use SysNAND FIRM if booting with R option is selected, FIRM will be loaded from the default EmuNAND instead of the first one and you can choose a different one with the directional pad, in the same way you would select the EmuNAND
• Changed the logic of the NIM update patch to only be applied when booting with R
• Hid the New 3DS CPU setting on Old 3DS
• Show descriptions for the options on the bottom screen
• Fixed support for pre-9.0 FIRMs. Luma3DS now directly supports >= 5.x FIRMs, as intended
• Fixed crashes for people with pre-patched Home Menu and NS module
• Added boundary checks for files loaded from SD
• More code refactoring

Dev version:

• Fixed crashes on some Old 3DS FIRMs (such as 9.0)
• Added displaying a partial stack dump on the bottom screen when handling an exception

v6.1.2

On both branches:

• 1.x and 2.x NATIVE_FIRM are now supported on SysNAND with the FIRM writes patch, this allows you to update retaining A9LH on every system version.
• PIN changes: you can now set the PIN length and easily change the PIN (you will get a prompt when exiting the config menu, which can be skipped with START), booting SAFE_MODE is easier with a PIN, the PIN file gets deleted when disabling the PIN lock.
• The TWL dev launcher patch has been removed as it's no longer needed and causes incompatibilities with a lot of NTR/TWL games.
• New config.bin format which allows to automatically discard the configuration as soon as it becomes incompatible with new Luma3DS releases.
• Large amounts of code refactoring and cleanups.

On dev branch only:

• Fixed crashes on New 3DS with the "Disable access checks" option enabled on FIRMs between 9.3 and 10.4. Unfortunately the service and archive checks patch can't work on said firmwares, and won't be applied.
• ARM9 debugging has been removed from TWL and AGB FIRMs as it didn't work and didn't serve a real purpose.
• The "Disable access checks" option has been renamed to "Patch SVC/service/archive/ARM9 access".

v6.1.1

On both branches:

• Fixed a likely issue with the TwlBg patch and made it selectable, as it triggers antipiracy checks for some DS games and possibly causes other issues.
• Fixed 3ds_injector picking up the previous boot configuration, which caused several bugs (like the NIM update patch activating when not needed - remember to select "Use SysNAND FIRM if booting with R" if you use a SysNAND setup).
• 1.25s speed boost on boot.
• Minor cleanups.

On dev branch only:

• Fixed another critical bug in the exception handlers.

v6.1

On both branches:

• TwlBg is now patched on-the-fly to implement the patch that allows NitroHax and other homebrews to work correctly (big thanks to ahezard, Normmatt et al. for the patches. No setup is required at all.
• Fix various bugs

On dev branch only:

• Fix critical bugs in the exception handlers.
• The UNITINFO patch has been ported to TWL/AGB firms (though it's useless). Its behavior has been inverted for dev units.

v6.0.1

This is a quick release to (tentatively) address issues users are having with the .dat payload.

• Updated ctrulib (should fix CakeBrah and menuhax 3dsx launchers)
• Fixed bug that could cause a payload being mistakenly launched after creating a new pin
• Minor cleanups

Note for dev branch users: there was a bug affecting exception handlers in this release. Please use the latest commit
