Cool articles :) I got into emulation in the late 90s and eventually wrote both an NES and Genesis emulator. I always appreciated how cleanly organized Sega’s systems were, at least superficially considering the memory and register layouts.
You should take a look at Sega’s arcade systems, which were very cool, especially the Model 1, 2, and 3. Supermodel, an open source Model 3 emulator I co-wrote, and MAME have good emulation of Model 3 and 2, respectively, these days. Absolutely fascinating rendering architecture. It was early modern 3D when things were still weird and custom, before the industry standardized on OpenGL and Direct3D.
