- 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.

And also move the location of IPS/BPS patches for (non-KIP) sysmodules
to /luma/sysmodules/<titleId>.<ips/bps> and only require "Load ext
firm/modules" option for it.
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.
This was a long-standing bug since Luma3DS v8.0.
If you changed the homebrew title and didn't immediately reboot, then
the ExHeader during termination would not match the ExHeader that was
was used for loading the process, and thus sysmodule process refcounts
would get all messed up.
The obvious solution to this is to ensure no application is running
while changing the hbldr titleID (hence the changes in custom PM).
This was quite possibly one of the cause of homebrew failing to load
when using N3DS H&S.
... 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.
When "load external firms and modules" is enabled, Loader will load the
sysmodule from /luma/sysmodule/<titleid>.cxi (all uppercase, and with
the N3DS title ID bit if relevant) and skip patching. Note that this is
a title ID here, not a process name (unlike what we do for KIPs).
While this is aimed at enabling people to easily load replacements for
official sysmodules, you can load your own custom sysmodules that don't
correspond to anything installed. You can use gdb to do so:
set remote exec-file <tid>
run
Not tested (except for HM which is known to work).
And restrict code.bin and exheader.bin to when *both* "external firm
and modules" and "game patching" are enabled.
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).
Caching exheader for applications launched through Home Menu has very
little benefit, as UnregisterProgram is called a lot, and, for 3DSX,
boot.3dsx/target 3DSX can be changed at any time.
Faithfully implement the PASLR algorithm official Loader
uses (it's not very good). Physical address space layout
randomization means that the layout of the pages in physical
memory are randomized, but doens't randomize the virtual addresses.
Also refactor some parts of our Loader impl a little more.
Let's not pretend in 2022 that it needed things from rosalina sysmodule
- it did not.
This moves 3DSX loading from Rosalina to Loader, and also removes all
the dependencies Loader had to other Luma3DS components (if kernel ext.
is missing, a default config will be used). This means that, as long as
you replace Loader to the one in here, you will be able to properly load
3DSX files.
Changes:
- hb:ldr is now hosted in loader
- hb:ldr LoadProcess, PatchExHeaderInfo, DebugNextApplicationByForce:
all removed
- fix a bug where some malformed 3DSX files were not rejected
- grant access to CONFIG11 registers to 3DSX homebrew
- move dirty homebrew chainload (when HM. isn't loaded nor loadable) to
pm
- pm:dbg (ext.) PrepareToChainloadHomebrew: removed
- 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
