 ## Hex Addresses
 Minecraft: Pi Edition has no symbols so you must patch the hex address of an instruction instead of using a function name. Hex addresses can be found using tools like [Ghidra](https://ghidra-sre.org) or [RetDec](https://retdec.com). To find out what a function does, you can find its equivalent in Minecraft: Pocket Edition 0.6.1 and use its name for reference because Minecraft: Pocket Edition 0.6.1 includes symbols.

 ## C++ Strings
 Minecraft: Pi Edition was compiled with an old version of GCC, so when interacting with C++ strings, make sure you set ``-D_GLIBCXX_USE_CXX11_ABI=0``.

 #### Docker Versions
 While the distribution-provided version of Docker is fine for most systems, in rare cases it can be outdated and cause bugs. Before reporting a bug, try using the official builds of Docker. These can be installed by following your distribution's instructions at https://docs.docker.com/engine/install.
 
-### Specific Notes

-#### Debian/Raspbian Buster
 By default Raspbian Buster ships an older version of the package ``libseccomp2``. This package is used to block certain dangerous system calls from running inside Docker containers. The included version accidentally blocks the system call ``clock_gettime64``, this causes bugs inside Minecraft: Pi Edition. However, the Debian ``buster-backports`` repo includes an updated version. You can enable the ``buster-backports`` repo and update ``libseccomp2`` by running:
 
 ```sh

-### PinePhone (Mobian)
-This supports running on a PinePhone using Mobian. However, you will need to attach a keyboard and mouse because Minecraft: Pi Edition does not have touch support.
