I found out about MiSTer via LGR's MiSTer Multisystem video, since then I've been enjoying it very much.
One thing I've had difficulties with was the original OS. Despite it being designed to be an appliance, it seems very brittle to store an OS's worth of data (and precious saved games / hard drive images) on a exfat SD card. Also, any modifications you make to the OS might be lost come update time.
I want to be able to run Arch on my MiSTer! If you want to do the same this project is for you.
Chat with other MiSTerArch users on:
This repository contains the PKGBUILDs for the arch linux arm packages required to run the MiSTer hardware. Including MiSTer's official uboot, kernel, binaries and support files (ex: .rbf files for cores). Ideally all updates will now be done through arch package managers, and there should be no need to run MiSTer's update scripts.
Complete builds of these packages can be found in the binaries
repo of this org. It's also served with gh-pages, which means it
can be directly added as a repo in /etc/pacman.conf
so your MiSTer knows
where to get MiSTerArch packages automatically at update time. See
installation instructions for how.
Some binary packages that are easy to "build" on a MiSTer (ex: mister-bin, mister-menu) are also mirrored on the AUR, in order to delegate the frequent repackaging to the each MiSTer device (similar to what the older update scripts used to do, but easier to manage). This might become handy once we get a couple [PKGBUILDs that can automatically version themselves](https://wiki.archlinux.org/title/VCS_package_guidelines#The_pkgver()_function).
We follow the -bin and -git naming conventions of the rest of the Arch community. The only added exception: -bin suffix is not required for bitstreams (pretty much all of the cores), as running quartus to compile a new binary on an armv7 MiSTer CPU would be laughable.
The main MiSTer binary and quite a few MiSTer scripts are hardcoded to
use /media/fat
as a case-insensitive location for doing everything.
For now this path's contents is under the user's control. One can even mount
an old style exfat partition using /etc/fstab
. For now mister-bin
's
post-install hook
has a suggestion on how to populate things in Mister by cloning
Distribution_MiSTer.
There's a couple of other techniques that might be of interest here:
/media/fat
/media/fat/
are not directly on the sd card, but others areIn the future it's possible we'll package up such content somewhere like
/usr/share/mister
, and use various mounts so MiSTer can see a view of
it in /media/fat
. Bonus: If packaged this way such packages could be
installed on x86 Arch machines that could act like a sshfs or samba server
for various MiSTers on a LAN.
Now that the MiSTer runs Arch, what more could it do?
