Cruel: /* Flags */

This page describes the format of the icon stored at [[NCCH#CXI|CXI]] ExeFS:/icon and [[CIA]] icons.
The size of icons is 0x36c0 bytes. The CXI icon is displayed by [[Home Menu]] and [[System Settings]](3DS Software Management), while [[CIA#Meta|CIA icons]] are dummies and not yet utilised by Dev 3DS' (as of rev 47586).

All encoded in UTF-16.
There are 16 app title structs(currently only 12 are used), each one for separate languages.

The languages by order of appearance:

* 1st: Japanese title name
* 2nd: English title name
* 3rd: French title name
* 4th: German title name
* 5th: Italian title name
* 6th: Spanish title name
* 7th: Simplified Chinese title name
* 8th: Korean title name
* 9th: Dutch title name
* 10th: Portuguese title name
* 11th: Russian title name
* 12th: Traditional Chinese title name

== Application Settings ==

Most of these flags are only used by the [[Home Menu]]. All of these are represented in SMDH files in little endian. But when documented below, the tables represent values in big endian.

=== Region Specific Game Age Ratings ===

These flags tell the 3DS the 'Age Rating' of the software for the below regions:

|}

Active ratings have a bitmask of 0x80, and inactive ratings have no bitmask at all. Ratings without the 0x80 bitmask are ignored. 0x40 bitmask indicates Rating Pending. 0x20 bitmask indicates No Age Restriction.
Age limits are set by adding the minimal age to 0x80 (for example, limiting to 12 years and up would give a bitmask of 0x8C)

=== Region Lockout ===

This u32 flag is what the Home Menu uses to determine the [[Home Menu#Region Lockout|Region Lockout]] of a title.

{| class="wikitable" border="1"
|-
! REGION
! BITMASK
|-
| Japan
| 0x01
|-
| North America
| 0x02
|-

|-
| Australia
| 0x08
|-
| China
| 0x10
|-
| Korea
| 0x20
|-
| Taiwan
| 0x40
|}

Regions are 'included' in region lock by setting their bitmask value. Nintendo defines region free as 0x7fffffff. Early in the 3DS' development, Nintendo grouped the Australian and Europe markets together. Nintendo defines market Europe as having the combined bitmasks of Europe and Australia. No 3DS' which check the Australia bitmask have been seen (Australia uses the European 3DS model).

=== Match Maker IDs ===

These IDs are an application's online gaming IDs.

=== Flags ===
The u32 is used for storing flags as bit-masks.

{| class="wikitable" border="1"
|-
! FLAG
! BITMASK VALUE
|-
| Visibility Flag (Required for visibility on the Home Menu)
| 0x0001
|-

| 0x0002
|-
| Allow use of 3D? (For use with parental Controls. An application can use the 3D affect, even when this flag isn't set)
| 0x0004
|-
| Require accepting CTR EULA before being launched by Home (see below)
| 0x0008
|-

| 0x0010
|-

| 0x0020
|-
| [[SMDH#Region Specific Game Age Ratings|Region game rating]] required
| 0x0040
|-
| Uses save data? (see below)
| 0x0080
|-
| Application usage is to be recorded. If this is not set, it causes the application's usage to be omitted from the Home Menu's [[Home_Menu#Cache.dat & CacheD.dat|icon cache]], as well as in [[????????|other places]].
| 0x0100
|-
| Disables [[SD Savedata Backups]] for this title. This is in addition to [[NS CFA|the blacklist]].
| 0x0400
|-
| New 3DS exclusive title. Shows an error if used on Old 3DS.
| 0x1000
|}

====Effect of SaveData and AutoSave====

These options have no effect on the performance of the application itself: they're used to select an appropriate warning when closing an application from [[Home Menu|Home]].

* Both off: "Closing software" (no warning if quitting directly with X)
* SaveData: "Do you want to close [...]? (Unsaved data will be lost.)"
* AutoSave: ?
* Both on: "Saving data and closing software..." (no warning if quitting directly with X)

=== EULA Version ===
This is the EULA version which is checked when the Accept EULA flag is set, the version is compared to one stored in the 3DS. If the SMDH version is greater, then the user will be prompted to accept the EULA.

{| class="wikitable" border="1"

|-
| 0x202C
| 0x01
| EULA Version Minor
|-
| 0x202D
| 0x01
| EULA Version Major
|}

=== 'Optimal Animation Default Frame' (for BNR) ===

This is a float, indicating the preferred (or 'most representative') frame for the banner animation.

=== CEC (StreetPass) ID ===

This u32 represents the application CEC ID. This is likely loaded by applications for use with the CEC services as well.

== Icon graphics ==

At offset 0x2040, there are two icons:
{| class="wikitable" border="1"
|-
! START
! SIZE
! DESCRIPTION
|-
| 0x2040
| 0x480
| Small - 24x24 (shown on top screen when pausing the app)
|-
| 0x24C0
| 0x1200
| Large - 48x48 icon (the general icon)
|}

Both of the icons are encoded in RGB565 meaning 16bpp. Although both icons are known to be RGB565, developers have the option of encoding icons (and banners) with the following encodings :

* RGBA8
* RGB8
* RGBA5551
* RGB565
* RGBA4
* LA8
* HILO8
* L8
* A8
* LA4
* L4
* ETC1
* ETC1A4

This does not necessarily mean the other encodings will be used, it is just that those are the options when compiling. Like we've seen with Super Mario 3D Land Nintendo has changed save file encryption, and likewise they can encode icons and banners differently ''should they choose to''. Currently we've seen just RGB565 so don't be fooled if an icon doesn't show up right! It is probably one of these formats above. Although we will probably not see other formats used for a while it's nice to know they have an opportunity to change.

The data is encoded in tiles (starting from size 8x8, continuing recursively).

If the buffer is like this:

{| class="wikitable" border="1"
|-
! 0
! 1
! 2
! 3
! 4
! 5
! 6
! 7
! 8
! 9
! 10
! 11
! 12
! 13
! 14
! 15
! 16
|-
|}

Then the image would look like this:

{| class="wikitable" border="1"
|-
! x=0
! x=1
! x=2
! x=3
! x=4
|-
| 0
| 1
| 4
| 5
| 16
|-
| 2
| 3
| 6
| 7
| ...
|-
| 8
| 9
| 12
| 13
|-
| 10
| 11
| 14
| 15
|-
|}

=TLS Root CAs=
Initially a HTTP context will not trust ''any'' root-CAs at all. Which root-CAs to trust must be ''explicitly'' specified via the add-root-CA service command(s).

RootCertChains can be used to easily select a particular chain of trusted root-CAs with multiple HTTP contexts, without having to re-send each of the root-CA commands for each HTTP context. The maximum number of RootCertChains that can exist for an user-process, is only 2.

When using the context-specific RootCA commands such as [[HTTPC:AddTrustedRootCA]] where [[HTTPC:SelectRootCertChain]] was already used, the cert will just be added to the selected RootCertChain.

=ClientCert Contexts=
These are basically the same as RootCertChains except for TLS client cert+privk. The maximum number of ClientCert-contexts that can exist for an user-process, is only 2.

IDBE

2016-07-10T01:08:10Z

Cruel:

IDBE is Nintendo's title icon database. Entries contain title icon, region, and name (in various languages). Similar to the [[SMDH]]. All game titles are on the server (excluding DSiWare?), including demos and updates.

== URLs ==
<nowiki>https://idbe-ctr.cdn.nintendo.net</nowiki>/icondata/'''%02X'''/'''%016llX'''.idbe

'''%02X''' seems to always be 0x10 (?)

'''%016llX''' is the title id.

'''%d''' is an optional title version.
== Encryption ==
The icon database is encrypted with AES-128 CBC. All icons use the same IV and one of 4 possible keys (as specified by the key index in the header).

The IV/keys are likely hardcoded on the 3DS, but not sure where. [http://wiiubrew.org/wiki/Nn_idbe.rpl#Encryption They are also on the WiiU].

GPU/Internal Registers

Cruel: /* GPUREG_TEXUNITi_PARAM */

[[Category:GPU]]

== Overview ==

GPU internal registers are written to through GPU commands. They are used to control the GPU's behavior, that is to say tell it to draw stuff and how we want it drawn.

Each command is at least 8 bytes wide. The first word is the command parameter and the second word constitutes the command header. Optionally, more parameter words may follow (potentially including a padding word to align commands to multiples of 8 bytes).

In the simplest case, a command is exactly 8 bytes wide. You can think of such a command as writing the parameter word to an internal register (the index of which is given in the command header). The more general case where more than one parameter word is given is equivalent to multiple simple commands (one for each parameter word). If consecutive writing mode is enabled in the command header, the current command index will be incremented after each parameter write. Otherwise, the parameters will be consecutively written to the same register.

For example, the sequence "0xAAAAAAAA 0x802F011C 0xBBBBBBBB 0xCCCCCCCC" is equivalent to a call to commands 0xF011C with parameter 0xAAAAAAAA, 0xF011D with parameter 0xBBBBBBBB and 0xF011E with parameter 0xCCCCCCCC. If consecutive writing mode were disabled, the command would be equivalent to three consecutive calls to 0xF011C (once with parameter 0xAAAAAAAA, once with 0xBBBBBBBB, and finally with 0xCCCCCCCC).

Invalid GPU command parameters including NaN floats can cause the GPU to hang, which then causes the GSP module to hang as well.

The size of GPU command buffers must be 0x10-byte aligned; the lower 3 bits of the size are cleared. A common pitfall is having the finalization command (write to register 0x0010) not executed because it was the last 8 bytes of a non-0x10 byte aligned command buffer, and having the GPU hang as a result.

=== Parameter masking ===

Using a value other than 0xF, parts of a word in internal GPU memory can be updated without touching the other bits of it. For example, setting bit 16 to zero indicates that the least significant byte of the parameter will not be overwritten, setting bit 17 to zero indicates that the parameter's second LSB will not be overwritten, etc. This means that for instance commands 0x00010107 and 0x00020107 refer to the same thing but write different parts of the parameter.

=== Types ===

There are three main types of registers :
* configuration registers, which directly map to various rendering properties (for example: [[#GPUREG_FACECULLING_CONFIG|GPUREG_FACECULLING_CONFIG]])
* data transfer registers, which can be seen as FIFOs that let us send sequential chunks of data to the GPU, such as shader code or 1D samplers (for example: [[#GPUREG_SH_CODETRANSFER_DATA|GPUREG_GSH_CODETRANSFER_DATA]])
* action triggering registers, which tell the GPU to do something, like draw a primitive (for example: [[#GPUREG_DRAWARRAYS|GPUREG_DRAWARRAYS]])

=== Aliases ===

It is possible for multiple register (sequential) IDs to correspond to the same register. This is done to leverage the consecutive writing mode for GPU commands, which makes it possible for a single command to write data to multiple sequential register IDs. For example, register IDs 02C1 through 02C8 all correspond to [[#GPUREG_VSH_FLOATUNIFORM_DATAi|GPUREG_VSH_FLOATUNIFORM_DATA''i'']] so that a consecutively writing command based at 02C0 will write its first parameter to [[#GPUREG_VSH_FLOATUNIFORM_INDEX|GPUREG_VSH_FLOATUNIFORM_INDEX]] and ever subsequent ones to [[#GPUREG_VSH_FLOATUNIFORM_DATAi|GPUREG_VSH_FLOATUNIFORM_DATA''i'']]

== Miscellaneous registers ==

=== GPUREG_FINALIZE ===

{| class="wikitable" border="1"
! Bits
! Description
|-
| 0-31
| unsigned, Trigger P3D Interrupt (0 = idle, non-zero = trigger)
|}

Writing to this register seems to signal the GPU to stop processing GPU commands from the current buffer; any command following a write to this register will be ignored. The value written to this register does not appear to matter, although 0x12345678 is the value typically written by commercial software.
Failure to write to this register in any command buffer will result in the GPU hanging.

This register sets a shader unit's code entry point.

For geometry shaders, this sets the entry point for the single shader unit which can be dedicated to running geometry shaders, regardless of the current geometry stage mode. This is means that while this register is normally used to set the geometry shader entry point, it can also be used to set this single shader unit to run from a different entry point than the other three, even when running a vertex shader.

For vertex shaders, this sets the entry point for the shader units set to vertex shader mode. Depending on the current geometry stage mode this can include either all 4 shader units or just 3 of them.

This register sets the shader unit input register index which will correspond to each attribute contained by the input buffer (which in the case of geometry shaders is the vertex shader output buffer) for attributes 8 through 15. For example, having bits 0-3 set to 5 means that, in the shader program, v5 will contain the input buffer's 9th attribute.

|-
| 31
| unsigned, Transfer mode (0 = float1.7.16, 1 = float1.8.23)
|}

This register sets the shader unit's target floating-point register and transfer mode for the data transfer system. As such it is typically used right before [[#GPUREG_SH_FLOATUNIFORM_DATAi|GPUREG_''SH''_FLOATUNIFORM_DATA''i'']], though writing to one register does not make writing to the other mandatory.

=== GPUREG_''SH''_FLOATUNIFORM_DATA''i'' ===

{| class="wikitable" border="1"
! Bits
! Description
|-
| 0-31
| Floating-point register component data
|}

This register is used to set the components of a shader unit's floating-point registers, each having 4 components. The data format which should be written to it depends on the transfer mode set with [[#GPUREG_SH_FLOATUNIFORM_INDEX|GPUREG_''SH''_FLOATUNIFORM_INDEX]]. This register functions as a FIFO queue: after each time a 4-component uniform register is successfully set, the target register index is incremented, meaning that groups of uniforms with contiguous register IDs can be set with only one initial write to [[#GPUREG_SH_FLOATUNIFORM_INDEX|GPUREG_''SH''_FLOATUNIFORM_INDEX]].

* In the case of float24 transfer mode, data should be sent by writing three words which are the concatenation of the float24 value of the uniform register's 4 components, in the reverse order. Assuming each letter corresponds to 4 bits, the format becomes:
** first word : ZZWWWWWW
** second word : YYYYZZZZ
** third word : XXXXXXYY
* In the case of float32 transfer mode, data should be sent by writing four words which are each the float32 value of the uniform register's 4 components, in the reverse order.

This register is used to set the offset at which upcoming shader code data transferred through [[#GPUREG_SH_CODETRANSFER_DATAi|GPUREG_''SH''_CODETRANSFER_DATA''i'']] should be written.

=== GPUREG_''SH''_CODETRANSFER_DATA''i'' ===

{| class="wikitable" border="1"

This register is used to transfer shader code data. This register behaves as a FIFO queue: each write to this register writes the provided value to the GPU shader code memory bank at the offset initially set by [[#GPUREG_SH_CODETRANSFER_INDEX|GPUREG_''SH''_CODETRANSFER_INDEX]]. The offset in question is incremented after each write to this register.

=== GPUREG_''SH''_OPDESCS_INDEX ===

Homebrew Applications

Cruel: Undo revision 15769 by Plutooo (talk)

==Installing==
Applications are installed by copying the necessary files to the 3ds/ folder in the root of the SD-card. Most applications come with two files:
* (app name).3dsx: The executable.
* (app name).smdh: The icon/metadata.

The [[Homebrew Launcher]] will scan the sdcard for all .3dsx files, but will only display an icon for those who have one according to the format described above.

GPU/Commands

2015-09-14T03:27:48Z

Cruel: Add combiner function definitions

This page describes the structure of the buffer submitted via the registers at [[GPU|0x1EF018E0]] (or equivalently via [[GSP_Shared_Memory|GX command]] 1). This buffer is used for GPU commands including functionality equivalent to OpenGL commands.

[[GPU Internal Registers]] provides a more structured overview for the available commands but is still work in progress, and hence should be used as a complementary source of information.

=== Overview ===
Each command is at least 8 bytes wide. The first word is the command parameter and the second word constitutes the command header. Optionally, more parameter words may follow (potentially including a padding word to align commands to multiples of 8 bytes).

In the simplest case, a command is exactly 8 bytes wide. You can think of such a command as writing the parameter word to an internal register (the index of which is given in the command header). The more general case where more than one parameter word is given is equivalent to multiple simple commands (one for each parameter word). If consecutive writing mode is enabled in the command header, the current command index will be incremented after each parameter write. Otherwise, the parameters will be consecutively written to the same register.

For example, the sequence "0xAAAAAAAA 0x802F011C 0xBBBBBBBB 0xCCCCCCCC" is equivalent to a call to commands 0xF011C with parameter 0xAAAAAAAA, 0xF011D with parameter 0xBBBBBBBB and 0xF011E with parameter 0xCCCCCCCC. If consecutive writing mode were disabled, the command would be equivalent to three consecutive calls to 0xF011C (once with parameter 0xAAAAAAAA, once with 0xBBBBBBBB, and finally with 0xCCCCCCCC).

Invalid GPU command parameters including NaN floats can cause the GPU to hang, which then causes the GSP module to hang as well.

The size of GPU command buffers must be 0x10-byte aligned; the lower 3 bits of the size are cleared. A common pitfall is having the finalization command (write to register 0x0010) not executed because it was the last 8 bytes of a non-0x10 byte aligned command buffer, and having the GPU hang as a result.

=== Command Header ===
{| class="wikitable" border="1"
! Bit
! Description
|-
| 15-0

|-
| 19-16
| Parameter mask
|-
| 30-20
| Number of extra parameters (may be zero)
|-
| 31
| Consecutive writing mode
|}

=== Parameter masking ===

Using a value other than 0xF, parts of a word in internal GPU memory can be updated without touching the other bits of it. For example, setting bit 16 to zero indicates that the least significant byte of the parameter will not be overwritten, setting bit 17 to zero indicates that the parameter's second LSB will not be overwritten, etc. This means that for instance commands 0x00010107 and 0x00020107 refer to the same thing but write different parts of the parameter.

==== Command Sets ====

===== glDrawElements() =====
See [[GPU_GL_Arrays|GPU GL Arrays]].

===== glClear() / glClearColor() =====
The GPU does not have dedicated commands for clearing the color buffer, therefore applications implement color buffer clearing by rendering a quad. Applications normally store this vertex and color [[GPU_GL_Arrays|array]] in the GSP application heap.

===== Command 0x0081 =====
This sets current texture info, see [[GPU Textures|GPU textures]].

Alphablending and color logic op can't be used together. Attempting to issue commands 0x0101 and 0x0102 at the same time can freeze the GPU.

For blending to work correctly, color buffer reading needs to be enabled (see command set 0x0112). Otherwise zero values will be used as destination color/alpha.

{| class="wikitable" border="1"
! Bit
! Description
|-
| 0
| Weird mode (see below)
|-
| 1
| When set, nothing is drawn to the color, depth and stencil buffers. This bit can cause a noisy picture when used with bit 0 (this seems to also cause the depth buffer's endianness to be reversed, and forces stencil values to 0xFF).
|-
| 8
| Selects blending mode. 0 = color logic op, 1 = alphablending
|-
| 23-16
| Unknown, typically set to 0xE4. No observed effect when changing this.
|-
| 25-24
| 0 = normal, 1-3 = apply dithering (3 = 0% source)
|}

When "weird mode" is enabled, the source color/alpha values are ignored. Instead, each 16-bit value in the destination color buffer is converted according to its bits 14-8, as follows:
* if bits 14-8 are between 0x00 and 0x03, the value is replaced with 0x0000
* if bits 14-8 are between 0x7D and 0x7F, the value is replaced with 0x7FFF
* in all other cases, the value is left unchanged

=== Parameter value format for command 0x0101 ===
This command controls alphablending. To disable alphablending, the value is set to 0x01010000.

=== Types for command 0x02C0 ===

The 0x02C0/0x02C1 is actually used as a generic way to set uniforms, regardless of what they represent. 0x02C0's parameter represents the ID of the destination GPU register (0x0 is c0, 0x1 is c1 etc). As such, the meaning of the data being sent over is entirely dependant on the shader currently in use.
The values below may be "default" values used by Nintendo's openGL implementation.
