It is an expensive hobby. The computer and hard drives i had lying around. The speaker i got from work… Work was getting rid of it.
It was about $100 in wood. probably $100 for the buttons, but they are light up ones so you can get them cheaper. The player 1 and 2 joystick were $50 each i think, but they are programmable. Player 3 and 4 are normal joysticks, and they are like $10 i think. The trackball was $50 i think. I’ve probably spent about $500 or so so far. You could probably do it for less, or build a smaller bar top type cab.
My dad got the street fighter cab from an arcade that was going out of business for like $100 a long time ago.
