Is there really any "loading" going on, or is that just a branding screen? Those consoles use ROM chips that were fast enough, and the Genesis, for example, only had 64 KB of RAM, so there wasn't even the need or possibility for "loading" a lot of things into the RAM like today, nor was the CPU fast enough to compute anything during boot that couldn't be pre-loaded into the ROM. I also remember some of those being totally skippable as well, not only in the Genesis but also in other consoles. On the Neo Geo, for example (same CPU as the Genesis, 68000), putting a coin completely skips the (kinda long) 7 second logo intro.
