Title says it I want to play old games without going broke. Do I need a vpn, where do I find roms. There are a lot of games I want to try but only so much money so help would be appreciated. PS2 games N64 games PS1 games and the like.

Edit got f zero gx playing on dolphin but it jumps up and down on fps. Playing with the settungs is making me this that the computer might not be powerful enough. Gonna try more later because brain outta juice.

Thanks everyone who helped.
