One of the greatest strengths of GCC is the sheer volume of architectures which it can target, many of which are niche or legacy platforms. But how has this support translated into real-world utility? How well are some of these platforms still supported? Using the Sega Dreamcast and its SH4 CPU as a case-study, we take a look at just how far GCC is allowing its homebrew community to take the platform, providing modern C23, C++23, Objective-C, D, and even some Rust to the 1990s game console.
