Amoeba Jump


Atari 2600


by Dion Olsthoorn (Dionoid)



Amoeba Jump is a vertical jumping game for the Atari 2600 where your objective is to guide an amoeba (a single-celled creature) up a never-ending series of platforms without falling. The higher you get, the higher your score will be.

There are three different platform types:


Yellow - these are the basic, stable platforms

White - these are instable platforms that disappear after you bounce off them once

Blue - these platforms are harder to hit because they move back and forth horizontally


Jumping on a red or green spring-button will give you a short boost and some bonus points, but best of all: it makes the little amoeba rejoice! When your score gets beyond 1000 points, little oval-shaped bacteria can appear on the platforms, which can be eaten by the amoeba. Each bacteria holds one of the six letters of the word A-M-O-E-B-A. Collect all six and the single next time you jump on a spring, you will get a super boost.


The screen wraps around, which means that the Amoeba can leave one side of the screen and immediately reappear on the opposite side. You're going to need this to reach some platforms!


Amoeba Jump is the first Atari game developed by Dion Olsthoorn. He initially planned to build this game for the Commodore 64, but after reading the book "Racing the Beam" he decided to buy an old Atari VCS and challenge himself to write a game for this strange, limited but wonderful machine.

Wizard of Wor Arcade
Atari 2600
by John W. Champeau (johnnywc)

Wizard of Wor is a new port of the 1981 Bally Midway arcade game of the same name, with considerable improvements over the CBS version released over 35 years ago. Wizard of Wor arcade will feature all the levels from the arcade, multi-player action, substantial speech (using the AtariVox), 4 skill levels, and much more! Improvements from the CBS version include:

  • Multiple player modes: 1 player (yellow or blue, with or without robot player), 2 player simultaneous.
  • Much improved graphics (thanks to Nathan Strum), including single-line resolution sprites and much less flicker)
  • Much improved sounds (thanks to Michael Haas)
  • All the arcade mazes (not sure how many were in the CBS version)
  • Wizard speech with Atarivox (not sure how many phrases, 50 or so?)
  • Four skill levels
  • Arcade-like gameplay
  • Pause feature
  • High scores for each skill level (saved to Atarivox+ also)
  • Multi-tap joystick compatible allows 2 players with Atarivox

Here's a video of the game running on a real 2600 with an AtariVox connected so you can also hear the speech:

Atari 2600 Trak-Ball Hacks
Atari 2600
by Thomas Jentzsch and Jeff Johnson

For some time we had a hack by Thomas Jentzsch of Missile Command for the Atari 2600 that allowed it to be used with Atari CX-22 and CX-80 Trak-Balls, as well as Atari ST and Amiga mice. Since the original Missile Command arcade game featured a Trak-Ball controller, adding Trak-Ball support to the 2600 version seemed like a no-brainer. And it radically changes the game! Using a mouse with the game is also a unique experience, since you just "point and click" where you want to fire the missiles (almost makes it too easy!)

Over the past few years, Thomas Jentzsch and Jeff Johnson have added this magic to several additional games, bringing the total number of games modified to use a trak-ball or mouse to eleven!

  • Centipede
  • Challenge of Nexar
  • Colony 7
  • Marble Craze
  • Millipede
  • Missile Control
  • Missile Command
  • Plaque Attack
  • Reactor
  • SpaceMaster X7
  • Star Wars The Arcade Game

Additionally, many of these games support all three controller types in a single cartridge! These versions can detect which controller you have plugged in. Some of the larger games (such as Marble Craze) still require a separate cartridge for each controller type (CX-22/CX-80, Atari ST Mouse, and Amiga Mouse). All of these trak-ball hacks are available in NTSC and PAL versions. We don't have these in the store yet, but we plan on adding them after PRGE. All of them available to play at the show!

Aardvark
Atari 2600
by Óscar Toledo G. (nanochess)

Welcome to the nature! Guide Bongy the Aardvark in its quest for the most delicious ants hidden in the earth. The Bongy's tongue is pretty sensitive and you should be careful when searching in the ants' catacombs, because if ants touch the body of your tongue then Bongy will lose a life.
The most delicious ants, the queen ants, are deep in the chambers of catacombs, but watch out, as there are poisonous worms that should be eaten only from the back. And in the night there can appear deadly spiders that you should prevent from touching the tip of your tongue.
You can choose your starting level if you're an experienced player, number of starting lives, and when you receive a bonus life. You can also select your playing mode from Novice, Easy, Normal, Hard and Expert.
Develop a strategy to enter the anthill, as the game gets progressively harder as you advance! This addictive game takes the Atari 2600 hardware to its limits in this 32K game with extra RAM.
Game programmed by the highly-respected developers Oscar Toledo G. (nanochess, author of Space Raid) and Thomas Jentszch (Thrust/Cave 1K). Artwork and graphics by cartoonist Nathan Strum.

Plague

Atari 2600

by János Zoltán Fehér

 

Plague is about a doctor of a less hopeful age as the fatal illness spread and brought disease to the lands, searching for ingredients for the medicine that could save people.

 

Your main goal in the game is to progress from screen to screen, avoid hazards and collect the shiny herbs that stand out from the dark environment. Remember, the doctor can't fight back. If you get injured, you can use one of the collected herbs to heal yourself, but that would reduce the chance to find the useful combination in the last segment.

 

The game contains several unique rooms and puzzles, a boss fight and a little pharmacy.

Crescent Memories
Atari Jaguar
by BitJag

Odd-It has returned to the Crescent Galaxy to make sure that the adventures of Trevor and Friends never end. Whether it's dodging pipes as a disembodied jaguar head in Flappy McFur, playing space tennis with a friend in Odd-Ball, or surviving on a merciless planet in order to see another day in Odd-It Will Be Watching, Crescent Memories is sure to bring a little bit of something for everyone to enjoy.
Crescent Memories will include 3 games packed into 1 cart. Flappy Mcfur, Odd-Ball, and Odd-It Will Be Watching.

Flappy McFur is based off the unexpected hit Flappy Bird, with some additional gameplay modes and elements to add to the already addictive nature of a modern classic. Flap your way to the Crescent Galaxy dodging pipes and collecting coins.
Odd-Ball is a new twist on the familiar table tennis format. With holes at the top and bottom of the screen, and obstacles with game altering pickups that traverse the center of the screen, be ready to create unfamiliar strategies in order to beat the CPU or your human opponents.
Odd-It Will Be Watching pits you against the environment of an unmerciful far flung planet. You must survive 64 days trying to keep your crew warm, their belly's full, and sane enough to not give up hope of rescue.

With a grill in the midst of chaos, you control Pete the chef to build burgers for eagerly awaiting customers. Sounds like an easy job, right?

Robot Zed
Atari 2600
by Chris Spry (Sprybug)

One robot remains in the force and it's up to you rescue your fallen robot colleagues. You control the last Robot, Robot Zed. In this demo, you run through a rogue-like, horizontally scrolling base level to find and locate one of the fallen robots, to take back to your base for repairs, so you can use their abilities in future levels. But to find your buddy, you must run through the base and battle the enemy's own robot force.
There are four different robots in total. The standard robot will sometimes supply you with energy when defeated. The other three robots will give you their power once defeated. After you gather their power you can change with down and jump to cycle through your collected powers to pick. Be careful with how much you use them. Every time you use a special power, it'll drain your power tank. Once you run out, you will return back to normal power until you gather more power capsules from those three special enemies.
Good luck in your quest and don't forget to have fun!

Xevious
Atari Jaguar
by Shamus Hammons

Xevious is a vertical scrolling shooter arcade game released by Namco in 1982, and distributed by Atari in North America.
In Xevious you pilot a combat aircraft called a Solvalou. You will fly through a host of flying enemies and land-based obstacles that try to shoot you from the sky. Your mission is to reclaim the enemy-occupied Earth by shooting and bombing the enemy into oblivion. You must skillfully pilot your spacecraft through harder and harder encounters with the enemy.
The Jaguar version of Xevious was written from scratch by Shamus Hammons. It’s a very faithful rendition of the arcade game, and even maintains the proper aspect ratio, which is why black bars are visible on the left and right sides of the screen in the Jaguar version.
