Way back in the last century, I bought a Sega Dreamcast. One of the reasons that I like it (apart from some great games), was that there was a burgeoning homebrew development scene for it. I went and bought the various bits of hardware I thought I needed to get going, but ended up never doing anything, and it all sat in storage for 20 years. Recently, I unpacked everythying and decided to figure it all out.
