* Code Patching (ARM Only)
* Logging

The code patching is ARM only because it relies on hard-coded ARM instructions. However, this is irrelevant since code patching is only needed in ARM code (to patch MCPI).
### ``symbols``
This component contains all MCPI symbols.

MCPI-Reborn has several dependencies:
* MCPI (Bundled)
* GLFW (Only In Client Mode)
* Open GL ES 1.1
* EGL

* ZLib (Required By LibPNG; Bundled)

# Manual Installation
[Download Packages Here](https://jenkins.thebrokenrail.com/job/minecraft-pi-reborn/job/master/lastSuccessfulBuild/artifact/out/)
## Supported Distributions
* Ubuntu 20.04+
* Debian Bullseye+
## Picking A Package
### Name Format
```
minecraft-pi-reborn-<Variant>_X.Y.Z~<Distribution>_<Architecture>
minecraft-pi-reborn-<Variant>_X.Y.Z_<Architecture>
```
### Picking A Variant
* ``client``: Client mode, use this if you want to play MCPI
* ``server``: Server mode, use this if you want to host a dedicated MCPI server
### Picking A Distribution
This specifies which version of Debian MCPI-Reborn was built against. Which one you should use depends on your current distribution. If your distribution supports it, you should use ``bullseye`` for better mouse sensitivity.
* Ubuntu 20.04+: ``bullseye``
* Raspberry Pi OS Buster: ``buster``
* Debian Bullseye+: ``bullseye``
* Debian Buster: ``buster``
### Picking An Architecture
* ``amd64``: x86_64, use this if you are using a device with an AMD or Intel processor
* ``armhf``: ARM 32-Bit, use this if you are using an ARM device (like a Raspberry Pi)

# Sound
One of MCPI-Reborn's main modifications is a sound-engine since MCPI doesn't include one by default[^1]. However, it can't be used out-of-box because MCPI doesn't contain any sound data and MCPI-Reborn can't include it because of copyright.
MCPE's sound data can be extracted from any MCPE v0.6.1[^2] APK file, just place its `libminecraftpe.so` into `~/.minecraft-pi/overrides` and you should have sound!
[^1]: The mute button is just leftover code from MCPE, it doesn't actually do anything in un-modded MCPI, however it is connected to MCPI-Reborn's sound-engine.
[^2]: This isn't a hard limit, an MCPE v0.8.1 APK would probably work, but don't rely on it.
