This page documents the format of the '''NCCH Extended Header''', or '''exheader''' for short.
This page documents the format of the '''NCCH Extended Header''' (''exheader'' for short).
The exheader, has two sections:
The exheader has two sections:
* The actual exheader data, containing System Control Info and Access Control Info,
* And a signed copy of NCCH HDR public key, and exheader Access Control Info. (This version of the Access Control Info is used as limitation to the actual Access Control Info)
* The actual exheader data, containing System Control Info (SCI) and Access Control Info (ACI);
* A signed copy of NCCH HDR public key, and exheader ACI. This version of the ACI is used as limitation to the actual ACI.

The AccessDesc Signature covers the ''NCCH Hdr Public Key'' and second ''Access Control Info''. The AccessDesc public key is initialised by the bootrom.
The <code>AccessDesc</code> signature covers the NCCH HDR public key and second ACI. The <code>AccessDesc</code> public key is initialised by the boot ROM.
When loading the exheader, [[FIRM|Process9]] compares the exheader data with the data in the <code>AccessDesc</code> (note that not everything is compared here). When these don't match, an error is returned. The Process9 code handling this validation was updated with [[6.0.0-11|v6.0]]; the only change in this function seems to be the check for the "Ideal processor" field.

In the exheader data, the ideal processor field is a bit-index, while in the <code>AccessDesc</code> the ideal processor field is a bitmask. When the bit specified by the exheader field is not set in the <code>AccessDesc</code> field, an error is returned.
<pre>if((1 << exheaderval) & accessdescval == 0) return error</pre>
During a FIRM-launch when a <code>TitleInfo</code> structure was specified, the field at offset [[FIRM#FIRM_Launch_Parameters|0x400]] in the FIRM-launch parameters is set to the SystemMode of the specified title, however in some cases other values are written there. With [[8.0.0-18]] NS will now check the output of [[PTM|PTMSYSM]] command <code>0x040A0000</code>, when the output is non-zero and a certain NS state field is value-zero, the following is executed otherwise this is skipped. With that check passed on [[8.0.0-18]], NS will then check (<code>Flag2 & 0xF</code>). When that is <code>value2</code>, the output value (used for the FIRM-launcher parameter field mentioned above) is set to <code>value7</code>. Otherwise, when that value is non-zero, the output value is set to 6.

In order for the exheader to have any of the above new bits set, the <code>AccessDesc</code> must have the corresponding bit set, otherwise the invalid-exheader error is returned.
Homebrew which runs under a title which has the above <code>cpuspeed</code> flag set, runs much faster on New3DS. It's unknown how exactly the system handles these flags.
When launching titles / perhaps other things with [[APT]], [[NS]] uses [[PTMSYSM:ConfigureNew3DSCPU]] with data which originally came from these flags; NS does this regardless of what the running 3DS system is. However, due to a bug(?) in NS the value sent to that command is always either 0x0 or 0x3. When calculating that value, the code only ever uses the cpuspeed field, not the cache field: code to actually load and check the value of the cache field appears to be missing.

When in <code>Legacy</code> mode, the actual memory layout is the same as in <code>New3DS Prod</code>, except the available application memory as reported to the application is reduced to the Old3DS size.
The exheader value for the New3DS system mode value must be ≤ to the <code>AccessDesc</code> value, otherwise the invalid-exheader error is returned.

==== Service Access Control ====
This is the list of [[Services_API|services]] which the process is allowed to access, this is registered with the [[Services|services]] manager. Each service listed in the exheader must be listed in the <code>AccessDesc</code>, otherwise the invalid exheader error is returned. The order of the services for exheader/<code>AccessDesc</code> doesn't matter. The <code>AccessDesc</code> can list services which are not in the exheader, but normally the service-access-control data for exheader/<code>AccessDesc</code> are exactly the same.
This list is submitted to [[SRVPM:RegisterProcess]].
