FTA:
"DreamShell
The Dreamshell is the operating system for the Sega Dreamcast based on the KallistiOS[0] kernel. It has a dynamic loadable modular system and interface for creating applications with XML UI and both C/C++ and Lua script on. You can see examples in ready-made applications and modules, drivers for various devices, formats and interfaces. Examples for audio and video decoding, compression, packaging, binding, network, emulation, scripts and more. From hardcore low-level assembler to high-level applications. There are also large subproject is the ISO Loader, which contains emulation of BIOS system calls, CDDA playback and VMU, also it can hooking interrupts for various SDKs and more."
"KallistiOS is an unofficial development kit for the SEGA Dreamcast game console with some support for the NAOMI and NAOMI 2 arcade boards.
KOS was developed from scratch over the internet by a group of free software developers and has no relation to the official Sega Katana or Microsoft Windows CE Dreamcast development kits. This has allowed it to fuel a thriving Dreamcast homebrew scene, powering many commercial releases for the platform over the years. It supports a significant portion of the Dreamcast's hardware capabilities and a wide variety of peripherals, accessories, and add-ons for the console, including custom hardware modifications that have been created by the scene.
Despite the console's age, KOS offers an extremely modern, programmer-friendly development environment. Using the latest GCC toolchain, it supports the entirety of C17 and C++20 including their standard libraries, along with support for portions of C23, C++23, Objective-C, and various POSIX APIs. Additionally, KOS-ports offers a rich set of add-on libraries such as SDL, OpenGL, OpenAL, and Lua for the platform."[0]

240pTestSuite

11 198 7.7 C

A homebrew software suite for video game consoles developed to help in the evaluation of upscalers, upscan converters, line doublers and of course TV processing of 240p video. The Wii and Dreamcast versions have modes for 480i and 480p evaluation as well.

If I might add: using 240pTestSuite or something similar (there are specific hardwares to output a grid signal and the likes) is a good way to check for convergence issues or bad picture quality overall.

MaplePad

3 185 6.9 C

🍁 Dreamcast controller emulator using RP2040. Supports 8-page memory card, SPI/I2C OLED for VMU LCD, and rumble.

The cycle accurate assembly language has enabled a number of timing sensitive FIFO data processes. What had to be done with FPGA's before has some limited support with PIO. I hope RPI increases the number of instructions and simultaneous running PIO machines in the future.

Multi Platform 3D Library for PlayStation 2 /Dreamcast / Game Cube /Wii / PSP
libGimbal

3 60 8.8 C

C17-based extended standard library, cross-language type system, and unit testing framework targeting Sega Dreamcast, Sony PSP and PSVita, Windows, Mac, Linux, Android, iOS, and WebAssembly.

I'm a huge academic fan of what GTk has accomplished (thanks to their GObject type system), and as much as I know the C89 crowd who thinks macros are all evil probably abhor this kind of thing, I think GTk is one of the most epic, impressive, ambitious C codebases in existence. Witness as non-OO C matches, rivals, and quite often beats Qt on equivalent classes/features in plain C... It's even above "just C++ style C," as they have added features like a property and signal system...
Such a fanboy it inspired my own type system and massive core library, libgimbal, which uses a type system similar to GObject and targets game consoles like the Sega Dreamcast: https://github.com/gyrovorbis/libgimbal
