There's a lot of emulators for windows out there.
Can start with dreamcast emulator first cause they have good games and reasonable graphics.
Not sure if I can share the exact name but you can search google for dreamcast emulators starting with the letter R******. Then find dreamcast roms by google also.

Then can move to other platforms emulators also, Psx, Ps2, DS, etc.
Good luck!
