Zoo Keeper (2600, Champ Games)

Brick pattern display:  Zoo Keeper uses a special technique to draw the vertical lines in the brick pattern on the first and third screens.  This feature requires that the game be played on a CRT with real hardware or that S-Video video effects are enabled (in Stella).

Excellent work so far!

 

But I think you can use any TV mode in Stella, not just S-video.  RGB/Composite/Bad Adjust also show the vertical lines.  So there's some choice there, as long as one of the TV modes are used.

Never played this game until I got me an xbox with CoinOps on it. Very challenging game and was amazed to see this for the 2600. I've been following its development and eagerly awaited the demo. Does not disappoint, amazing work by Champ Games yet again. This version is just as tough as the arcade version and look forward to this being released next year. Outstanding!

Been playing the mess out of this since last night, any chance our demo will include the escalator level as well as the game develops. Watched the ZPH stream and I'm gathering ours only has 4 regular and 2 platform stage right?

Hello there!

 

The demo should include 6 zoo stages, 3 platform stages and 2 escalator stages.  After completing the 2nd escalator stage, it should wrap back to round 1 zoo stage.  :)

Thanks Stephen!  Yes, you are correct, any of the the TV effects in Stella will simulate the vertical brick pattern - thanks for the clarification! :thumbsup:

Sweet, wasn't sure because I've yet to get passed the 2nd platform level lol. Kicking my butt but I'm determined. Going to be playing this as well as some other Champ games this holiday season.

Hi there,

As promised, here are the demo ROMs for Zoo Keeper, both NTSC and PAL60.

I saw the demo on ZeroPageHomebrew's Twitch channel. Very impressive as usual.

 

How would these graphics work on for PAL50 refresh? Would the screen refresh too slow to give the same effect of NTSC or PAL60?

Hi Dennis!  Thanks!  This one has been a year in the making but we're pretty happy with how it's coming along. :)

Hmmm, maybe - honestly I'm not even sure what causes the vertical lines to appear.  I just happened to notice the effect while working on the MAPPY logo with Thomas Jentzsch last year and we were trying to make the 'M' larger with another sprite and I saw the vertical line down the middle that inspired me to try to use it for a brick pattern like Zoo Keeper. :D

Is it just me, or is there a spot on the lower right bottom wall that, when moving counter clockwise, that Zeke just stops?  If you try running or jumping over it, he won't continue counter clockwise?

Hmmm, I just tested it and Zeke moves fine around all corners.  Note that, like the arcade, when you reach a corner, you can keep pressing in the same direction as you hit the corner, he'll keep going around the corner for a bit.  At that point, you need to press the joystick in the direction he's moving.  For example, as you approach the lower right corner going counter clockwise, you are pressing the joystick right.  As you approach the corner, keep pressing right and Zeke will take the corner and start moving up for a bit.  At that point, you should start moving up so Zeke continues in that direction, otherwise he will stop if you're still pressing right but he needs to move up.

 

Hope that helps!

Thing is, this wasn't at the corner.  It was about an inch the the right of it.  I'll try again

I never heard of this game before I started seeing it in the AtariAge forums.  I love the gameplay and graphics, but my personal preference is to have the bricks solid, but then again I was playing on Stella on a laptop so even with the various effects I may not have been getting the optimal appearance.  That being said, I cannot wait to see this one completed and added to my "to buy" list along with other great Champ Games, like Mappy.

Thanks!  I should have mentioned in the original post that you can set the LEFT DIFFICULTY switch to A to disable the vertical lines in the bricks which eliminates the flicker on the play field. :idea: :)

Luckily I read the forum first! The gameplay was very addictive with building new bricks. It is amazing to read about the development of these games and just imagine what could have been had these been developed in the past. Keep up the great work.

 

I see so many posts with people showing off their Activision or Spectravideo or Parker Bros collection.  I imagine people showing off their Champ Games collection will be soon to come.

One thing i still can't get my head around with Zoo Keeper and Galagon is the shear amount of sprites on one screen. I can't help but think a Lemmings port would be possible with this sort of technology.

Hello all,

 

Here are the updated ROMs for Zoo Keeper (demo #2).

 

:idea: The original demo (demo #1) and instructions can be found here.  

 

There are numerous bug fixes, game play enhancements and additional bells & whistles. 

 

Some of the major updates are:

  • Updated the bonus (escalator) stage to be more like the arcade, including:
    • Updated jump and collision logic with the cage
    • Added in Zeke "triple hop" start level animation (like the arcade)
    • Added in Zelda ❤️ graphic when she's rescued
    • Cages are multi-colored now
    • Updated jump logic to be more like the arcade
  • Added in Zoo rounds 7 - 12, plus additional platform and bonus screens
    • ROUND xx ENDED message displayed for rounds >=10 
  • Added in Savekey support to save high scores and game options (disabled in demo)
  • Added in 2 player (alternating) support (players take turns).  (disabled in demo)
  • Added in continue feature that allows the player to continue the current game (with the score reset to 0) up to 3 times.  (disabled in demo)
  • Updated the Zoo Keeper title logo to be shorter (same size as the arcade)
  • Updated the platform stage:
    • Updated monkey animation and throwing patterns to be more like the arcade
    • Increased height on the platforms to be more like the arcade
    • Tweaked the platform collision logic
    • fixed the bug where Zelda could not be rescued from the right side of the platform
    • added in platform bonus for jumping on top platform
    • added in sound effect when you land on a platform
    • the "SAVE ME" message is displayed intermittently during the level now (was only displayed at the beginning)
  • Added in the "CAN YOU HOLD IN THE LION?" intermission screen after completing Round 5 (needs music still)
  • Added support to display high scores up to 99,999,999
  • Updated the zoo stage:
    • Animals will return to the center when captured in a direct path
    • Added in higher frequency sound effects when jumping over more animals
    • Added support to display jump scores up to 30,000,000 :cool: 
    • Updated the brick fade/wipe animation when completing a level to be more like the arcade
    • fixed a bug where multiple animals could be caught with the net at the same time
  • Added in the Credits screen.  We're looking for someone to help with a couple tunes (the lion intermission tune and "NO BONUS" tune when no animals are captured) if anyone is interested! :D 
  • Updated the player score border to be more like the arcade
  • Changed the score color to match the skill level:
    • NOVICE: flashes green/yellow-green
    • STANDARD: flashes turquoise/purple (like the arcade)
    • ADVANCED: flashes red/red-orange
  • On ADVANCED level, the platforms will reverse direction when they are landed on.  This is experimental and may be removed or changed to only appear in later levels (it seems to be a tad too difficult) 
  • Modified flicker logic so Zeke is more solid.  This is very helpful for later zoo levels when there are many animals on the same horizontal area.
  • Changed the difficulty switch actions:
    • LEFT DIFFICULTY controls the location of bonus items on the zoo stage
      • If set to 'B', bonus items are always in the same location as the arcade
      • If set to 'A', bonus items are placed in random locations around the cage
    • RIGHT DIFFICULT controls the brick display pattern on the zoo and bonus stage
      • If set to 'B', the bricks are displayed with vertical lines between bricks (like the arcade).  Note the you must enable TV effects in Stella to see this properly.  In this mode, the bricks are a bit darker and flicker a little.
      • If set to 'A', the bricks are displayed in a solid pattern with no vertical lines between bricks and no flicker.

 

We estimate the game to be around 98% complete.  Nathan Strum has graciously volunteered to do the artwork for the game, and we expect the full version to be available sometime in August of 2020.

 

This is a fully-functional demo, with the following features disabled:

  • Savekey support has been disabled.  You can still enter your initials in the high score screen at the end of the game, but scores will not be saved.  Additionally, your game options are not saved.  
  • Two player (alternating) is disabled (one player only).
  • Continue feature is disabled.  In the full version, you are allowed 3 continues once your game ends to start the next game at the current level/screen.

Any feedback or suggestions are welcome.

 

Have fun!

John

 

NTSC version: zookeeper_20200308_demo2_NTSC.bin

 

PAL60 version: zookeeper_20200308_demo2_PAL60.bin
