RGME is simply fantastic. His Pokemon cry and sprite encoding is so well done. He did a charity Livestream once where he spent 4 hours decoding a Pokemon sprite by hand. I didn't watch it, because that's too much a time investment for me, but I still find it incredible.
I still can’t believe he actually offed himself. Marcan (or does he prefer Asahi Lina now?) gave us just about the most implausible scenario imaginable, told us that the Japanese government report would prove it (which it didn’t), then claimed they got it wrong (which, while possible, is certainly not plausible), and it wasn’t until a FOIA request was made and answered that we saw that, at least according to government records, it was all somehow true. Just an insanely odd situation and it was a shame to see Byuu take his own life when he had been in such a good place previously. I wish we knew what caused this.
Maybe I'm just old, but the same information that a lot of blogs and youtube videos show (though not Fabien's series above) and more can be grokked by scanning the development docs you can find on archive.org.
