@d0k3 thanks for the big update!!!
just wnt to ask will it be possible to build a godmode9 with enable/disable write to nand feature... so that building another one (safemode9)... protection will be integrated to godmode9...
Did you even try GodMode9? You know that there is no writing to critical stuff without unlocking it via a button sequence and that there is warning for everything?
I am seeing "8: BONUS DRIVE / IMGNAND TWLN" in the readme, says that the home menu can format it. How does one even set that up? What can it be used for outside of GODMODE9? I've got a n3DS XL if that helps at all.

It's in the readme, "You may set up the bonus drive via the HOME menu on 3DS consoles that provide the space for it.". If the option doesn't turn up for you, your console doesn't have that extra space in NAND. Currently I don't know of any software that would provide access to this memory or even use it in any way, so this is useful for GM9 only, as some kind of on device storage. Maybe other's will follow suit and this drive will be more useful in the future.
Just found that this became a part of the A9LH setup. I honestly use these programs (by these, I mean Decrypt9WIP) to make dumps of game carts, so I'll stick with Decrypt9WIP. It's much more familiar to me.

My N3DS has an additional ~600MB of space after the end of the actual CTRNAND. There are consoles that have even more. O3DSes always have very little to no additional space, and about N3DS / 2DS, just an elaborate guess, but newer consoles are more likely to have mroe space. And, well, as I said, only GM9 can access it right now. You can also dump it and access via OSFMount on PC.

This has been in so called 'alpha' for a long time, while growing an actual user base (right @Shadowtrance ? ). In fact this has been tested enough, and it should be rock solid by this time (read the thingy about challenge below). So Im releasing to you today...
Injecting files into files (must have exactly one file in clipboard)
Faster encryption/decryption of NAND partitions
Tweaked button react times
Half copied files are now properly removed
Countless smaller fixes and improvements
More stuff I possibly forgot
GodMode9 v0.5.1
What's new:
Simple hex editor is now included (only single byte changes, no inserts / deletes)
New hex view, utilizing both screens
Totally revised write permission system, now allowing granular permissions
Writing to memory is now allowed (when the permission is unlocked)
Improved handling when copying / moving to existing files
Encrypting / decrypting sector0x96 is supported (needs otp.bin on entrypoints other than a9lh)
Auto-scroll when holding arrow buttons, thanks to the ARM9 timer register
Multiple minor bugfixes
SafeMode9, a safe variant of GodMode9 which makes it impossible to brick
GodMode9 v0.4.0
What's new:
No more additional files are required for GM9 to work (=> no more slot0x05keyY.bin / aeskeydb.bin)
You can mount a RAMdrive in root via R+X (28MB for O3DS / 128MB for N3DS)
You can now calculate & compare file SHA-256s
Moving FAT files and folders is now possible
Safety check for A9LH when trying to overwrite A9LH regions
Extended and fixed the virtual memory feature
GW Launcher.dat support is deprecated and the Launcher.dat no more included in the archive.
Countless smaller fixes and improvements
GodMode9 v0.3.5
What's new:
You can now mount NAND and FAT images and use them as additional drive(s)
Hexviewer for files from any locations
Virtual Memory drive added (allows you to view and dump certain memory regions)
Dual pane handling added, switch with R + (Right / Left)
Vastly improved button react times on O3DS (thanks @AuroraWright)
More useful info displayed in directory view
Fixed filename input dialogue (this would fail on rare occasions)
Fixed case sensitive renaming
Some minor bugfixes
GodMode9 v0.2.0
Initial release version
Features:
Manage files on all your data storages: You wouldn't have expected this, right? Included are all standard file operations such as copy, delete, rename files and create folders. Use the L button to mark multiple files and apply file operations to multiple files at once.
Make screenshots: Press R+L anywhere. Screenshots are in BMP format.
Use multiple panes: Press R+left|right. This enables you to stay in one location in the first pane and open another in the second pane.
Search drives and folders: Just press R+A on the drive / folder you want to search.
Format your SD card / setup a RedNAND: Press the HOME button, select SD format menu. This also allows to setup a RedNAND on your SD card. You will get a warning prompt and an unlock sequence before any operation starts.
Run it without an SD card / unmount the SD card: If no SD card is found, you will be offered to run without the SD card. You can also unmount and remount your SD card from the file system root at any point.
Direct access to SD installed contents: Just take a look inside the A:/B: drives. One the fly crypto is taken care for, you can access this the same as any other content.
Build CIAs from NCCH / NCSD (.3DS) / TMD (installed contents): Press A on the file you want converted, the option will be shown. Installed contents are found (among others) in 1:/titles/(SysNAND) and A:/titles/(SD installed). Where applicable, you will also be able to generate legit CIAs. Note: this works also from a file search.
Decrypt and verify NCCH / NCSD / CIA / TMD / FIRM images: Options are found inside the A button menu. You will be able to decrypt to the standard output directory or (where applicable) in place.
Batch mode for the above two operations: Just select multiple files of the same type via the L button, then press the A button on one of the selected files.
Access any file inside NCCH / NCSD / CIA / FIRM images: Just mount the file via the A button menu and browse to the file you want.
Generate XORpads for any NAND partition: Take a look inside the X: drive. You can use these XORpads for decryption of encrypted NAND images on PC. Additional tools such as 3dsFAT16Tool are required on PC.
Directly mount and access NAND dumps or standard FAT images: Just press the A button on these files to get the option. You can only mount NAND dumps from the same console.
Restore / dump NAND partitions or even full NANDs: Just take a look into the S: (or E:/ I drive. This is done the same as any other file operation.
Compare and verify files: Press the A button on the first file, select Calculate SHA-256. Do the same for the second file. If the two files are identical, you will get a message about them being identical. On the SDCARD drive (0 you can also write a SHA file, so you can check for any modifications at a later point.
Hexview and hexedit any file: Press the A button on a file and select Show in Hexeditor. A button again enables edit mode, hold the A button and press arrow buttons to edit bytes. You will get an additional confirmation prompt to take over changes. Take note that for certain file, write permissions can't be enabled.
Inject a file to another file: Put exactly one file (the file to be injected from) into the clipboard (via the Y button). Press A on the file to be injected to. There will be an option to inject the first file into it.
You need some way of running ARM9 payloads. One possibility is a 3DS console on FW 9.0...9.2 with *hax installed, another is an installed arm9loaderhax, but there are more. The included readme file details all possible ways.
A Word of Warning:
This is powerful stuff, but precautions are taken so you don't accidentially damage the filesystem of your console. The write permissions system protects you by providing warnings and forces you to enter an unlock sequence for enabling write permissions. It is not possible to overwrite or modify any important stuff without such unlock sequences and it is not possible to accidentially unlock something.
After unlocking write permissions on SysNAND, any writing change to your CTRNAND can result in a brick (still recoverable via A9LH). Writing changes to your TWLN partition can lead to a partial brick, leading to your console not being able to run DSiWare / DS cartridges anymore. If you unlock the A9LH write permission, you are able to overwrite and remove the A9LH installation in your system, which allows you to full brick your console (in that case, only recoverable via hardmod).
As always, be smart, keep backups, just to be safe.
A Challenge for you (preferably hardmod owners):
As I wrote, GodMode9 is written to be rock solid. So, I challenge you to make it crash or at least do something unexpected / unwanted (like writing to NAND without write permissions, breaking files, etc...). If you manage to do so, and give us a description of what you did in thread, you get a free mention in the opening post.
@capito27 managed to crash GodMode9 by removing the SD card while it was in use (without dismounting). There is nothing much that I can do about this, but doing this almost counts as vandalism and is basically the same as removing a game cart while in use .
Is this CTRXplorer v2.0?
No. While GodMode9 and CTRXplorer do have overlapping functionality, both projects are completely separate. CTRXplorer actually has additional stuff in there (like a text viewer) that may never be in GodMode9. It also has much better compatibility and includes a functional CIA, which is not possible with this. If all you want to do is to manage the files on your SD card, I do in fact recommend you use CTRXplorer instead of GodMode9.
Credits:
As always, this wouldn't have been possible without the help from several people. So, my thanks go to:
Archshift, for providing the base project infrastructure
Normmatt, for sdmmc.c / sdmmc.h
Cha(N), Kane49, and all other FatFS contributors for FatFS
b1l1s, for helping me figure out A9LH compatibility
@dark_samus3 for discovery and initial testing of the 6x10 font.
