cargo-gccrs VS KallistiOS

We have `cargo-gccrs` for this, so a cargo subcommand which intercepts arguments given to `rustc` and converts them into `gccrs` arguments :)

https://github.com/rust-GCC/cargo-gccrs/

it's still in a relatively early stage as we are focusing on the compiler. But the idea is for it to be a drop-in replacement for compilation and execution operations, so you'd have `cargo gccrs build`, `cargo gccrs run`, `cargo gccrs test`, etc

gccrs is the compiler (like rustc). You can use cargo with gccrs : https://github.com/Rust-GCC/cargo-gccrs

See https://github.com/Rust-GCC/cargo-gccrs. There will definetly some sort of cargo support in the end. Either by having a behave-like-rustc wrapper around gccrs or by adding support directly to cargo or a cargo fork.

Cargo support for gccrs is part of this project:

Moreover, modules are less interesting to me in embedded development as is access to Rust's borrow checker for gaining certainty of small portions of larger projects, which are written in other languages.

- With the [cargo-gccrs](https://github.com/Rust-GCC/cargo-gccrs/) we want to integrate gccrs as seamless as possible into the Rust ecosystem. So yes.

"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]

You’re going to want to use KallistiOS to get started: https://github.com/KallistiOS/KallistiOS. It’s essentially a pseudo-OS for the Dreamcast that provides a lot of Linux-like functions.
