Zoo Keeper on Expansion Module #1

Recommended Posts

Just received my copy of Champ Games new Zoo Keeper cart, and it apparently does not boot up using Expansion Module #1 - anyone else have this same problem?

Tried other Atari carts including more current homebrews and everything works fine, so it seems to be this particular cart...

Hi Chris,

 

I don't have the Expansion Module #1 to test Zoo Keeper on, but if other Melody-based games run on it (Mappy, Scramble, Super Cobra Arcade, Galagon, Wizard of Wor, Epic Adventure, Space Rocks, Chetiry, Draconian, Stay Frosty 2, etc.), then Zoo Keeper should also run.  I do test all games, twice, once with the bare board and again after the board has been assembled into a cartridge, but I'm testing on 2600 and 7800 consoles.  It's possible that either Zoo Keeper doesn't run on the Expansion Module or there's a problem with that particular cartridge. 

 

If someone else with Zoo Keeper can test their copy on the Coleco Expansion Module #1, I'd greatly appreciate it!

I just tested on my module #1 and it works. 

Thanks, was this using a Harmony Cartridge or a Zoo Keeper cartridge?

Thanks all - I own other Melody cartridges that work (Space Rocks, Draconian), and if someone has a copy of Zoo Keeper that works on the module #1 then it must be my copy that's defective...

My copy of Deepstone Cavern doesn't boot on the Expansion Module #1 either.  However, Princess Rescue and Draconian does.  I will have to buy an Atari 2600 evidently.

These issues seem really weird as EM1 *is* really a 2600. I don't know if it is a problem with cart-to-slot connections, EM1 to Colecovision connection or not enough power being delivered to the cart for its extra functionality. As far as I know, the EM1 is not a watered down 2600 like the 2600 Jr that couldn't play Kool-Aid Man or the one-chip successor that has more limitations.

Might be worth someone testing on a Gemini system.

Interesting that some Melody carts (like Zoo Keeper) could possibly have higher power requirements that an EM1 cannot provide - I have several other Melody carts from Champ Games that play well on my EM1 as well as many standard carts, so I know it's not the EM1 slot or expansion port connections that are the issue...if additional power is the problem it would be good to know going forward.

How is everyone powering their ColecoVision system? That might be worth looking into and to test voltages under load… just in case.

 

Again, if someone has a Gemini system and the game, testing that setup could prove useful.

My Colecovision uses the original 28.5 watt "brick" transformer that came with the unit - no problems with it powering all expansion modules including the roller controller...

But as we know from years of experience, there are certain games that push the limits of the original CV Power Transformer and issues can arise whereas everything else works fine as you mentioned. One such game is Lord of the Dungeon with it’s battery backup… it could cause issues with a power transformer that is slightly off spec.

 

This COULD be a possibility with newer 2600 Homebrews that are pushing the hardware further than anyone could have imagined in the early 80s.

 

Just have to consider all the possibilities and have everyone help out by testing on all the variations of hardware that can be used to play the game. Testing voltages under load would be the best test option.

 

I’m still very interested to hear if there are any issues when played on the Coleco Gemini system.

I'm using Canadian Power Supply.  It takes awhile for the system to boot to working state after being off for a long period of time.  Usually sprites x position more than 128 pixels start to phase mirror at 0-128 and sometimes glitch out the vram a bit. I usually put Knightmare on for awhile since it does pushes the VDP during demo mode to unglitch it after awhile.  After I played Draconian for a half hour.  Then I took out the Atari expansion module and didn't bother to reinsert the SGM to play test the game I'm making.  The sprites are perfect and no phasing or mirroring glitch.  I'm using the non-passthrough modified Sega Controller.  Atari usually need 9 volt 500 ma for it to work.  And I still using the original power switch since the day I got it.  Draconian is CDF 32k board and Deepstone Cavern is Melody 32KB board.  I don't know if my Colecovision getting enough power.  The US Power Supply I have cord's are pretty bad so I retired that one so I don't risk frying the Colecovision.
