Gorf (program 1, with German Language ROM)
The player's goal is to defeat the Gorfian Empire and safeguard the future of mankind. Gorf is a single screen shoot-em-up in the classic "Space Invaders" mould, the prime difference being that Gorf offers 5 distinct levels of shooting action. The levels are as follows :
* Mission 1, Astro Battles : The first mission is more or less a straight clone of "Space Invaders", set against a sky-blue background. The player is protected by a glittering parabolic forcefield, which is gradually worn away by enemy projectiles. The forcefield also works in BOTH directions and therefore it must momentarily deactivate in order for the player's ship to fire out. To advance to the next mission, the player must destroy all the invaders.
* Mission 2, Laser Attack : The other missions are all set in space. In this mission, the player is faced with 2 formations each made up of 5 enemies. The formations are cross-shaped, and at the bottom of each formation is a single laser gun. The laser guns fire a long, dangerous yellow beam at regular intervals. At the same time, the other enemies may break formation and attempt to divebomb the player. Destroying a laser gun causes the corresponding formation to break apart. To advance to the next mission, the player must destroy all the enemies.
* Mission 3, Galaxians : This mission is a clone of "Galaxian". The player is faced with a swarm of galaxians, which continually divebomb and shower the player with deadly projectiles. To advance to the next mission, the player must destroy all the galaxians.
* Mission 4, Space Warp : A wormhole is situated in the middle of the screen out of which enemies ships emerge - one-at-a-time - and spiral outward at increasing speed; whilst growing larger and flinging fireballs at the player. The Space Warp level would have an influence on Konami's superb "Gyruss", released 2 years later. To advance to the next mission, the player must survive a number of these enemies.
* Mission 5, Flag Ship : The final mission is a 1-on-1 confrontation with the alien Flag Ship itself. The Flag Ship is one of the earliest examples of the 'boss' enemy in mainstream video games. It is equipped with its own forcefield, through which the player must blast in order to get a clean shot on the ship. It is also armed with a powerful fireball weapon. The player's weapon has a minor effect on the Flag Ship's hull, and can only blast off tiny pieces of it. This adds to the player's problems, as stray pieces of hull can destroy their ship. These pieces can be destroyed with a single shot. The only way to destroy the Flag Ship is to hit the glowing reactor at the heart of the ship, either by first blasting away the hull to expose it, or by managing to fire a shot directly into the tiny vent that leads to the reactor.
Each time the Flag Ship is destroyed, the player advances in rank. Initially, the player begins with the rank of Space Cadet, before moving on to Space Captain, Space Colonel, Space General, Space Warrior, and finally Space Avenger. The player's spaceship is equipped with a Quark Laser which allows the player to cancel a poorly aimed shot and fire another shot.

Tips sur Gorf (program 1, with German Language ROM)
* The action starts immediately as soon as you start your game. The first sight that will greet you are the Space Invaders. From that point on, the action will be non-stop with the only things changing are your rank and the difficulty of the enemies. Also, there is an interesting quirk in the game. If your ship hits a displayed score (after destroying some enemy), your ship will be destroyed. So avoid flying into scores. Also, you can only have one shot up at a time. This, though, can be countered by the fact that you can prematurely end a shot and fire another thus saving yourself a lot of time and perhaps your ship.
* Due to Gorf's limited hardware not being powerful enough to move the game's colourful sprites around easily, it's possible, on the Astro Battles screen, to slow the last two invaders down to a crawl; simply by repeatedly firing. On the Laser Attack screen, if you shoot all the enemy ships EXCEPT for the laser shooters, you can sit forever on the far left hand side of the screen. Useless, but interesting all the same.
* Astro Battles :
1) Fire immediately when the mission starts. You may get lucky and hit the Gorfian robot distributing the Space Invaders. Also fire at the invaders as they are being distributed for more points.
2) Instead of the normal 11x5 grid of invaders, you only have to deal with an 8x3 grid.
3) Instead of buildings to protect your ship, you now have a shield dome over you. It briefly disappears when you fire, but the invaders have to cut through it with their lasers.
4) Remember, you have a lot of maneuverability in your ship (i.e. you can go up and down) so it should be easy to avoid the invaders bombs.
* Laser Attack :
1) Your first priority should be the laser ships. Wait until they have fired and send a shot right up their laser cannon.
2) The escorts tend to make random movements so be wary of them coming at you from all directions.
3) As you advance higher in rank, everything speeds up accordingly.
* Galaxians :
1) Try to shoot the Galaxians when they are setting up to get the score for attacking Galaxians.
2) At first, only a couple will come down. After a while, though, the Galaxians attempt to swarm all over your ship. Since they each fire 3 shots apiece, this can present a particularly deadly situation.
3) Keep moving. There is no safe place (not even the corners).
4) At later ranks, it isn't uncommon for a whole bunch of Galaxians to attack your ship at once.
5) If you can, try to hit the Gorfian robot that sometimes bounds over the top of the Galaxians.
* Space Warp :
1) This is the mission that tends to kill off most players. You will see a black hole with dots in it. These dots represent the number of fighters you have to deal with coming out of the black hole. As a Space Cadet, you only deal with 12 fighters. From Space Captain onward, it will be 16 fighters.
2) Fighters leave fast or slow and rotate around the hole. In addition, they will also fire at you. It will take some fancy maneuvering to avoid both the fighter and the shot it fired.
3) Some fighters go around so fast, you just have to try to keep out of its way.
4) Sometimes fighters will launch a slow shot from the side of the screen. Watch out for these shots.
5) In the later ranks, it will take all of your skill to survive since everything moves very quickly on this mission.
* Flag Ship :
1) The Flag Ship will fly back and forth slowly. It will descend then ascend as it completes a back and forth movement.
2) There is a shield around the Flag Ship you must cut through to hit it. The Flag Ship can fire through the shield at you.
3) On the later ranks (starting with Space Captain), the Flag Ship is escorted by two Gorfian robots.
4) Plan your shots so you can expose the reactor. This will mean cutting through a little bit of the ship to accomplish this. Watch out for the debris you create since it is as deadly as the Flag Ship's laser shots. If you feel really daring, hit the debris for extra points.
5) After you have stripped the ship away from the reactor, a well-placed shot should obliterate the Flag Ship.
6) Again, in the later ranks everything moves much faster.

- 0.31: Alex Judd added clone Gorf (Program 1). Added better speech in Gorf (MAME Gorf voice samples v1.0: Kevin Estep (Original Machine samples and recording) and Alex Judd (Sound driver and sample manipulation)). Known issues: Colors are wrong in cocktail mode.
- 0.28: Mike Balfour added high score saving to Gorf.
- 0.27: Mike Coates improved again the Gorf driver. It's now (sort of) playable. Control: Arrows = Move around and CTRL = Fire. Known issues: Speed of invaders/galaxians/scrolling text is too fast. You can crash into the background (i.e. on the warp screen).
- 0.26: Mike Coates improved Gorf (which is still unplayable).
- 0.07: Added Gorf (Midway 1981). Game doesn't work, colors are wrong and missing sound. This game runs on the same hardware as Wizard of Wor, but doesn't work yet. It boots, shows some text on the screen and that's all.
STORY:
- The evil Gorfian Robot Empire has attacked. Your assignment is to repel the invasion and launch a counterattack. You will engage various hostile spacecraft as you journey toward a dramatic confrontation with the enemy flag ship.
