Another deep dive is in https://www.copetti.org/writings/consoles/master-system/

I've got a mostly-written emulator (in Rust). It's very easy to emulate, possibly the best gameplay bang for the emulator coding effort buck aside from NES. My main intent in writing this emulator is getting it running on an RP2350 board, like Adafruit Fruit Jam or Olimex RP2350pc.

It should also be possible to get the next generation (SNES, Genesis) on such hardware, but it's a much tighter fit and more effort.

Interesting article.. would have been easier to read the comparison in tabular format (SG-1000 v Master System v NES or so on).
