Sega Master System:
Just get a flashcart, load your (legally dumped) ROMs onto an SD card, plug it in…
…and you’re done.
Sega Genesis:
Use a flashcart (like EverDrive-style carts), load ROMs onto SD card and.. plug it in and play.
If you want to play sega CD games, you just burn them. That's it.
Sega Saturn:
NOW things get interesting.
Sega actually tried here.
You can use a Pseudo Saturn Kai card or Modchip.
The Pseudo Paturn Pai.. DARN IT!! it really is a tongue twister. You use a special cartridge. It lets you run burned discs.
So, burn your games, insert the cart and boot the game.
Sega Dreamcast:
This is where Sega just gave up.
The Dreamcast can run burned games
WITHOUT modding.
All you do:
Burn a CDI image onto a CD-R, put it in the console, and it just… works.
Sega Pico:
You are NOT hacking this.
It’s a children’s edutainment book-console hybrid.
Just no.
