- Move emuNAND hook to ITCM, fixing previously untested emuNAND support
for 5.0 (and possibly more versions). This was a very long-standing
bug
- Fix booting on versions 4.x to 8.x, and restore full support for 5.x
to 8.x. All Arm11 custom sysmodules and k11ext have been disabled on
4.x because the Luma3DS v13.0 changes couldn't be ported (this means
no Rosalina and no region-free and such, and while I could restore
some of the functionality, you should just update *after* installing
Luma, like you've been instructed to)
This commit adds all the changes made to the 3GX plugin loader fork of Luma3DS. The most important features are:
- Add 3GX plugin loader support. New service added to rosalina: plg:ldr
- Add svcControlProcess, svcControlMemoryUnsafe and improve svcMapProcessMemoryEx (breaking change)
- Allow applications to override certain configurations depending on their needs:
- Disable core2 thread redirection
- Disable game patching for the next app
- Force New 3DS speedup
- Force next application in a specific memory mode
- Block the opening of the Rosalina menu
- Add GDB commands to list all process handles and catch all SVC (latter is for IDA Pro as gdb client supports it)
- Other changes necessary for plugins to work properly. Please check changed files in this PR for more details.

This is a leftover from the Gateway era that has long lost its utility
and that unnecessarily complicated the code base.
Please just load an external FIRM from SD card if you need something
similar.
Also refactor the multi-EmuNAND code and CTRNAND mounting code.
... even when HPs aren't inserted.
This is aimed at people using Bluetooth audio hw mods.
There are some software limitations, please read the INI/option
description.
Closes#1828.
N3DS-only option. See config.ini for details and context. This should
make very demanding games (those which already use 3x clockrate and L2C
by default, like Pokémon US/UM) between 5 to 15% faster. Not widely
tested, and can potentially break some games and other apps.
For stuff like testing PASLR, *hax2x, khc3ds, etc.
Also fix a corner-case bug when changing the 3dsx app from itself to
itself, if its TID corresponds to the default.
Add config option to autoboot into 3DS and DSi homebrew menu, without
going through Home Menu (nor launching it).
For 3DS homebrew, this requires homebrew built with libctru v2.0.0 or
later (v2.0.0 was released 2.5y ago).
We simulate a "reboot into title" to achieve this. This being said, when
launching stuff like Pokemon US/UM on O3DS, Home Menu reboots into
itself and not the game directly. This will cause Home Menu to crash if
you use this feature and configure it to use a non-default memory layout
(but if you don't, Home Menu will work just fine).
This stubs checks in SvcCreateThread and SvcSetProcessIdealProcessor
that applied when creating threads on core2 and core3. This allows
non-sysmodules to create threads on core3.
Please note, core2 access was already being automatically granted to
3dsx apps for a long time (this is controlled through a kernel flag),
and other apps that needed it had that flag too.
This commit thus changes nothing for all these applications.
Do not create threads on core3 unless you know exactly what you're doing.
On N3DS, gsp (GPU sysmodule) depends on qtm (head-tracking sysmodule) which
runs many threads at very high priority on core3. Running code that needs the
GPU (including printf) on core3 can thus result in thread starvation /
deadlock.
If you just need an extra application core, just use core2 as it is intended
for that exact purpose and is by default completely idle.
Closes#1668
This is mostly a libctru bug (well, sort of).
This can only happen to built-in sysmodules, and to
processes waiting for err:f, that fail to obtain
handles through svcConnectToPort first try; and only
prior to 11.0.
Prior to fw 11.0, kernel didn't zero-initialize output
handles, and thus the output handle gets filled with
junk (leaked kernel stack data) in case of failure.
Libctru does not account for this, and closes such
handles anyway (in srvInit, errfInit, and possibly
more).
The problem is that, in our case, that garbage was
equal to 0x8000, actually a valid handle, in fact
the first handle to be created (and not closed) in
a process... a handle to KAddressArbiter.
Accidentally closing this handle resulted in one or
more KIPs spin-waiting and starving core1, resulting
in an inability to boot.
We fix this simply by replicating what recent k11 does,
in kext (for svcConnectToPort). For srvGetServiceHandle,
add two layers of safety.
- Add support for saving screen filters color temperature and NTP timezone offset (you still need to go to misc->save config)
- some advanced options moved to "in ini file only"; "patch games" is now enabled by default
- ntp: fix support for UTC+12 to +14
- remove deprecated custom svc 0x2e
