I have a Raspberry PI 3B model in great shape with a 16GB mini SD and an HDMI cable (if wanted). It already has emulator station with a ton of roms and emus dl and odyssey to stream movies. The sound is off since I have used it on multiple TV's so you will have to fix it via command in the console or just wipe the SD and start over.
I am willing to negotiate a price or trade it for some PS1, PS2, or PS4 games.
