{qlaunch-reimpl} is a very ambicious project, consisting on two custom library applets, a custom system application and a custom system applet, in order to replace the console's **HOME menu** with a custom, homebrew-orienteed one.
- For those who are interested in how the UI was done, this project is, like [Goldleaf](https://github.com/XorTroll/Goldleaf), a good example of how powerful [Plutonium libraries](https://github.com/XorTroll/Plutonium) can be in order to make beautiful UIs.
## Are you looking for help with themes? Check [this document](Themes.md) for more info!
- Themeable (not the same way official qlaunch themes work)
- Custom icons, background...
- Custom **background music** and **sound effects**!
- Option to show the suspended title in the **background** (like 3DS's HOME menu did!)
- Users
- PC-like login on startup (select user and use it for everything)
- **Password** support! (up to 15 characters)
> TODO: add more later...?
## Disclaimer
### Homebrew as applications
{qlaunch-reimpl} launches homebrew present (added) to main menu as an application, taking advantage of **flog**'s built-in application title, which was stubbed but not removed, thus it's content can be overriden via LayeredFS and launched.
Since launching this title should be impossible, it might involve ban risk, so **use it at your own risk**. {qlaunch-reimpl} **warns on launching titles this way**.
{qlaunch-reimpl} is split, as mentioned above, into several sub-projects:
### QDaemon (SystemAppletQDaemon)
This is the technically actual qlaunch reimplementation. However, to avoid memory issues it does not use any kind of UI (except console for development debug, which is removed for releases), and thus it uses 16MB of heap, while official HOME menu uses 56MB.
But, if all the functionality is handled by QMenu, why is this daemon process necessary? Well, mainly since the system applet process has a lot of unique code it's the only one who can use, specially, related to title launching, focus managing...
**TL;DR**: this is a simple daemon process which stays communicated with QMenu to perform tasks it is asked to so, specially with code it is the only one that can access.
### QMenu (LibraryAppletQMenu)
This is the HOME menu the user will see and interact with. It contains all the UI and sounc functionality, password, themes...
### QHbTarget
This is the name for two related projects, whose aim is to target and launch homebrew NROs in a simple way. It can be considered as a simple and helpful wrapper around [nx-hbloader](https://github.com/switchbrew/nx-hbloader)'s code:
#### System application (SystemApplicationQHbTarget)
This is the process which runs instead of flog, which is used to launch homebrew as applications.
#### Library applet (LibraryAppletQHbTarget)
This is the same process but, like in normal HOME menu and Album, it runs homebrew as an applet. However, exiting homebrew here will exit to HOME menu instead of exiting to hbmenu.
*QDaemon* daemon process, appart from usual (and special) HOME menu functions, it also sends the console's foreground display via USB as a raw RGBA8 1280x720 ~3MB buffer. **QForegroundViewer** is the PC tool (WinForms) which intercepts those sent buffers and renders them. It is a bit laggy, but can be *very* useful for taking quick screenshots!
Unlike the other projects, this one isn't essential and {qlaunch-reimpl} would be perfectly usable ignoring this sent data.
In order to check {qlaunch-reimpl}'s installation, you will need to pay attention to the `titles` directory of the CFW you're using.
### How do I know whether it is installed?
Check if folders `0100000000001000`, `010000000000100B`, `0100000000001009` and `01008BB00013C000` exist. (and that they aren't empty, or at least contain a `exefs.nsp` file)
### How do I remove it?
1 - Delete the following folders: `010000000000100B`, `0100000000001009` and `01008BB00013C000`.
2 - Delete **only `exefs.nsp` file** from `0100000000001000` directory (if there is a `romfs` folder present it could be a normal HOME menu theme)
## Compiling
You will need devkitPro, devkitA64, libnx and all SDL2 libraries for switch development.
Clone (**recursively!**) this repo (uses libstratosphere and Plutonium submodules) and hit `make` in root. It should build everything and generate a `titles` folder ready for use inside `SdOut`.
## Errors
If you get a crash using {qlaunch-reimpl}, please check:
- If the crash's title is `0100000000001000`, `010000000000100B`, `0100000000001009` or `01008BB00013C000` and **you know for sure you have this project in your SD**, then it is very likely related to this project.
- Switchbrew team for libnx and [hbloader](https://github.com/switchbrew/nx-hbloader), the base of *QHbTarget projects (they're some useful wrappers of hbloader in the end)
