Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

MiniScript on a bare-metal Raspberry Pi
If you're a developer and feeling adventurous, you can also try building it yourself. The source is all on GitHub. It uses the circle-stdlib project (which is circle plus some additions to support much of the C and C++ standard libraries) as a submodule; hopefully I've set that up correctly, but you could always clone that separately and place it in the MiniScript-Pi folder. Check out circle's build instructions for info on setting up your toolchain. (Mac users: be careful with the configure script, which does not work properly on MacOS; find me on Discord and I'll help you fix the script or configure manually.)

Bare Metal Emulation on the Raspberry Pi – Commodore 64
I suggest checking out circle https://github.com/rsta2/circle since it's basically a library for the pi hardware. I'm doing some experiments with it myself now.
-
Assembly coding without OS
You can also run a Pi without an operating system, programming it in C or C++ probably. See for example: GitHub - rsta2/circle: A C++ bare metal environment for Raspberry Pi with USB (32 and 64 bit)
- Bare Metal Emulators and launcher for RetroFlag GPI v1

Help with C64 Emulation (never used a C64 before in my life)?
BMC64 is VICE in a trenchcoat unikernel / bare-metal framework called Circle: https://github.com/rsta2/circle

Smalltalk-80 on Raspberry Pi: A Bare Metal Implementation
It uses the circle library (https://github.com/rsta2/circle) to provide a minimal runtime (mainly to interface with the hardware).

How do I get started with making my own Linux based OS on Embedded Hardware?
I experimented with circle the other day (https://github.com/rsta2/circle) Looks promising, and most likely within your knowledge of C/C++ development.

EmuTOS: A Modern FOSS Replacement OS for the Atari ST – and the Amiga Too
Natively would be amazing but a vast amount of work.
The way Apple moved classic MacOS from 680x0 to PowerPC was to write a tiny kernel emulator, with an API to run native stuff on the metal, and run more or less the whole OS under emulation, profile it and just translate the most speed-critical bits.
That's a lot of work for a FOSS project but given the performance delta between 1980s 680x0 and 2020s ARM, total emulation of the whole thing should be perfectly fine. It's how the PiStorm Amiga upgrade works.

So all I envision is something like Aranym:
https://aranym.github.io/
... running on top of Ultibo, say:
https://ultibo.org/
Or maybe Circle:

Solutions for >1GHz microprocessor with option for bare metal or freeRTOS
Circle is a C++ bare metal programming environment for the Raspberry Pi.

New in this sub, some questions…
The only other reasonable option would be to port it to a new platform which is popular that has a few well documented hardware interfaces so as not to create a hellish nightmare writing drivers. Maybe then you could do a one-off port to that platform (though you might have to re-target the HolyC compiler to target it instead if it is not x86_64). The Raspberry PI seems like a decent option here since there is already a baremetal C++ library supporting USB, keyboard, mouse, sound, video, and as an added bonus UART, I2C, SPI, GPIO. You would have good code examples for porting all the necessary drivers. But obviously this would still be a lot of work and the compiler would need to be re-targeted and user space adapted for running on ARM. That being said backwards compatibility is strong, ARM seems actually interested in keeping it that way (at least for now). The library I'm talking about is here: https://github.com/rsta2/circle

Smalltalk-80 on Raspberry Pi: A Bare Metal Implementation
it's based on this

my programming language
When I was googling the link for that book, I noticed an implementation someone else has done that might be helpful for you if you go this route: dbanay/Smalltalk.
- Ask HN: What's the best source code you've read?
- Bluebook Implementation of Smalltalk-80
-
Are there any materials that go through the internals of smalltalk and/or teach you how to implement a smalltalk-like language?
https://github.com/dbanay/Smalltalk And this is the bare metal implementation of it for RPi
