| 10 | 10 | The initial release of this game was in 1979, known as Pro-Tennis, |
| 11 | 11 | it is unknown if the hardware and/or ROM contents differ. |
| 12 | |
| 13 | This is an early VFD simple electronic tennis game. Player 1 is on the right |
| 14 | side, player 2 or CPU on the left. Each player has six possible positions |
| 15 | where to hit the ball. A backdrop behind the VFD shows a tennis court. |
| 12 | 16 | |
| 17 | NOTE!: MESS external artwork is required to be able to play |
| 13 | 18 | |
| 14 | | TODO: |
| 15 | | - 2-player mode doesn't work: the guys auto-serve and the left player |
| 16 | | always hits the net, mcu emulation bug? |
| 17 | | - difficulty switch changes mcu freq |
