So, since I sufficiently talked up stealth in this topic, let me take the opportunity to talk about some other awesome shit Taxman has done in the past - I posted a video of his Retro Sonic Dreamcast Proof of Concept a page back:
I actually got a story about this from Tax; turns out in the Dreamcast homebrew scene, Taxman was shunned for this. In Dreamcast homebrew, the kosher method of developing new Dreamcast games is to use KallistiOS, a freeware SDK that is community developed. The Dreamcast is pretty interesting because there are currently 3 SDKs for it: Sega had their official Katana SDK that came with the Katana hardware. We obviously now have KallistiOS (also called KOS, pronounced "Chaos") which is a project that was ultimately birthed from Marcus Comstedt (aka the patriarch of Dreamcast hacking). And, ironically probably the most famous,
Microsoft had an official Dreamcast SDK based off of Windows CE:
(This is why the Dreamcast says "Compatible with Windows CE" on the front. No, the Dreamcast doesn't have Windows CE inside, it's a reference to a deal Sega made with microsoft to provide a Windows CE compatible toolchain)
Anywho, it's illegal to use either the Microsoft Windows CE or Katana SDKs without license, even today, which is why KOS exists in the first place. Because of that, the community actually shuns info about the Windows CE and Katana SDKs, it's generally hard to find info about how to use either except in select IRC channels. Finding info about KOS is actually way easier (but still not easy).
So the story with Retro Sonic Dreamcast, and why Tax abandoned it: He used the Windows CE SDK to build it, haha. He had managed to get ahold of such a copy and built that proof of concept with it. That actually makes his work
more impressive as he did so without much documentation, no real community help, and because the Windows CE SDK is notoriously less performant than the Katana SDK.
But that's the reason why Retro Sonic on the Dreamcast never went past the proof of concept, he'd need a complete rewrite due to scene scrutiny. He actually DID start a rewrite... and that became the RetroSDK that powers Sonic CD, Sonic Mania, etc.
