Do you hear sounds? Screen is completely black, with or without a cartridge. Sounds like the TIA. Are you're chips socketed?

The multicart idea sounds good, except that the cost of the cart would be so much larger with a bunch of games on it, that few would buy it. If you wanted to give the developers of the games any money, the price of the cart becomes prohibitive. If you simply wanted to distribute more games on a physical medium, then multicarts are great. None of the people making 2600 games, can be doing it to even attempt to make a profit. I've been working on a game for 4 years(it still looks terrible, and is barely playable). I hope to someday to put it on a cartridge, and if I get enough money to go out to a nice restaurant, I will be very pleased. The idea of getting a game published on a machine that wasted so much of my youth appeals to me. Even if only 10 people might ever buy it. A section on the store here for buying the rom, would probably work, for most people. Maybe even an embedded emulator in Al's store, where you log in, and can play any game you purchased via a Java emulator. You're still talking a 100 dollars for a 100 hours of work.

I would check the caps and 7805 inside the atari. Most likely it's a bad 7805, that's not giving enough current. If you use a volt meter, it should show 5 volts. Here is a video that shows the inside so you can tell what you're looking at.
-
Do you have access to volt meter, and are you willing to open your atari? I'm not sure how much power the melody cart uses however, I suspect that the new boards use more power than the old school eproms did. If some of the components in both your atari's are a little flaky, you will get weird problems. Simple games will work while more complex games won't. Not because of new versus old. But becuase the new stuff has more stringent power requirements. Capacitors die slowly with years of use, and both consoles may have this problem. The 7805 is well known to cause problems as it ages as well.
-
Here is a youtube video that describes replacing the 7805.
-
Set the multi-meter to Volts,or v. Inside the atari in the upper left hand corner there is a square piece of plastic that sticks up with three legs, it's close to the power connector. Place one of the two leads from the meter to the middle leg, and put the other lead on one of the other legs, one leg will show 9-12 volts, and the other will show around 5. The black lead should be the one you put in the middle. I suspect you'll find that one to be 4.5v. Most likely this is the part that is broken. It's inexpensive and easy to replace. You can get a 7805 at any store that sells electronics components, such as radio shack or frys. They are 1 to 2 dollars. They can be found on ebay very easily as well. The 7800 is compatible with the 2600, there are only a couple games that don't work, and some of those can work if you modify the hosing so the cartridge will fit.
-
Do you have a multi-meter? Checking the voltage on the Regulator, is quick and easy. Since the game gets worse the longer it's on, it's probably heating up the 7805, and reducing it's output. The minimum the 7805 should be giving out is 4.95v.
-
If you use the selector switch for the power pin that would allow the unit to be used without an additional power supply. These were originally designed with eproms in mind. Would there be damage to an eprom? Modern devices are much less tolerant of this type of arrangement. 2k and 4k games probably had no trouble in these units.

You would need to use 24 pin card edge connector for each cartridge you want to plug in, and a donor 2600 cartridge. You only need the donor cartridge, so you have something to plug into the 2600 that looks and fits good. Then you will need to connect 23 of the pins on the donor cartridge to the corresponding pin on each of the edge connectors. So that pin 1 of the donor is connected to pin 1 on each of the edge connector. This is done for all the pins except the topside pin 11, which is the 5v pin. The power pin is how you're able to pick which cart you want active. You connect the 5v pin 11, to pin 11 on whichever cart you currently want turned on. A rotator switch would be easiest, this one at jameco, would allow you to choose up to 12 games. http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_576501_-1 This is the easiest way to create something like the kiosk, however it wouldn't have the menu, at the beginning, it would only have a mechanical method of game selection. If you want the menu, you would need to use one of the slots for the demo cartridge, which you can get the rom for at http://www.atarimania.com/game-atari-2600-vcs-imagic-selector-v2_15741.html

Boulder Dash didn't use any of the fetchers? I am mostly interested in being able to use extra rom. I know that it takes a special version of the Melody board to get the full 2Meg.
-
I assume that boulder dash uses special arm code. Is that available for others to use?
-
The capacitors aren't polarized so it doesn't matter which leg goes in which whole, when replacing. However when you replace the 7805 make sure it faces the same direction as the original one.
-
I would replace the 7805. The harmony uses more power than most cartridges, so you are more likely to see problems when using it. You can also replace the green caps. They vary based on what model you have. They can all be had at Radio Shack usually. Should be about 2 dollars in parts. If you have a meter, you can check the 7805, it should be 4.90v to 5.1v. Anything else and it's probably not at it's peak performance.
-
I would say it's probably the 7805 or the chicklet capacitors They both are cheap, and pretty easy to replace if you're handy with a soldering iron. The caps are little green things that look like chicklets, and I think they are .22uf 100v. The 7805 is right next to the power connector. It a black square with three legs.

Can DPC+ work with all the mappers. I would like to use it with the boulderdash 3e mapper.

The shielding built into the Atari is an FCC requirement, to prevent unwanted stray signals from entering or exiting the Atari. You don't want to mess up your neighbors TV. However magnetic fields from the TV should cause no permanent harm. Static and water are the only things to really worry about. Walking across you carpet and touching any of the metal contacts is way more likely to do damage. Having said that though, Atari's are built like tanks. I remember when I was little and my Atari was on a chair next to the tv. My mom was walking by and tripped on the controller, pulling the atari off the chair, and it hit the floor. I continued playing, and put the Atari back on the chair when I was done with that game.

I'd like to see some farm animals. Pigs, Cows, Chickens, Goats, Horses, etc.

Chopper command is my favorite. After that Phoenix, Vanguard, fantastic voyage, and empire strikes back.
-
Thanks that fixed it. It had an include fixed math statement, but not div_mul. I just assumed the sample would be correct, and I has messed something up in the installation.
-
I just installed visual batari basic. I load up the zombie sample. I cannot get the sample game to work. What did I setup incorrectly. When I compile I get the following

On the Atari, it wouldn't be just another RPG. I can count on my fingers the number of RPGs, that I know of for the 2600. I would love to see another one. But why use the swordquest title, call it Zodiac, or something like that. The only good thing about the swordquest titles, were the comic books.

The fry guys stole his pants, and he put a new pair on.

I like to collect any console that uses cartridges. I have all the new systems, but I just love the cartridges. One advantage of carts, is that multi-carts can be made. With the multi-carts you don't need to find all the games, and can store the ones you have, just keeping out one cartridge. I find it much more enjoyable to play the games on the original systems. It seems every system has a gem, not found elsewhere.

I always loved infiltrate. I think it's difficulty ramped up very well. They looked like fry guys when I was little as well. It should have been a mcdonalds game. I thought the box was simply showing the same guy in different poses.

Best exclusive games
in Atari 2600
Posted
What are the best exclusive 2600 games? Games that came out in the 2600 lifespan. I always liked Haunted House, and I don't believe it was a port of anything or ported to any other machine during the 2600 lifetime.
