  1. From the Stella mailing list:

     

    "It is simply 16 cropped and connected screenshots of colors.bin running on

    Mac Stella, with the odd numbered colors (which Mac Stella erronously

    displays) removed. As such, its accuracy is limited to however acurate

    Mac Stella is."

     

    You can probably find colors.bin and run it on an emulator that supports PAL color (like PCAEWin) to get the PAL colors.

  2. The Atari basically has a 40x192? resolution background (very low res), two 8 bit wide bitmapped sprites, a three box/line/box things you can move. The game "Frogs and Flies" illustrates this perfectly.

     

    The "sprites" are high resolution compared the background. There are only two bitmapped ones, but you can copy them multiple times on one screen. Programmers later started using multiple copies of the sprites not just for the "players" but also for backgrounds and other stuff, making games appear to have better resolution. For example, the text in Basic Programming is made by copying and changing the shape of the sprites many times during one draw of the screen.

  3. Some of my favorite rare ones are:

     

    Quadrun

    Rescue Terra I

    X-Man (not really fun, but funny)

    Wall Ball

    Mangia

     

    A couple of my least favorite are:

    Music Machine

    Chase the Chuckwagon

  4. It's probably a prototype, but personally, I wouldn't spend a lot of money on anything like that unless I saw the board inside the cartridge. Xevious is a standard 8k ROM which can easily be put on a modern Chris Wilkson bankswitching board. So you could build the same thing that's in that auction for about $10.

     

    Most prototype auctions appear to be legitimate, but I've seen a few that look really fishy.

  5. Here's what I don't have:

     

    working 7800 (never can find them)

    4 switch 2600 (don't like them as much)

    kids controllers, light gun, steering paddles(hope to get these soon)

     

    A few cool things I do have:

     

    2 Wico Trackballs

    128 game menu-driven multicart (homemade)

    Cuttle Cart (awesome)

    Commodore Paddles

    2600 6-slot pushbutton cartridge switcher

    Atari 1040ST w/80286 board (runs DOS under TOS!)

  6. Well I'll be... This is from the Chisolm Trail manual:

     

    "1. Turn the computer ON and wait for the master title screen to appear. Then slide the module into the slot on the console.

     

    2. Press any key to make the master selection list appear. To select the module, press the key corresponding to the number beside CHISHOLM TRAIL.

     

    NOTE: To remove the module, first return the computer to the master titles screen by pressing QUIT. Then remove the module from the slot..."

     

    Appearently you don't have to do this, because I've been turning it off to take the cartridge out for years.

  7. The biggest problem is that many Atari games use flicker to appearently display several things at once. So a screen shot will be missing half (or more) of the action. Here's my patented process for getting good screen shots with PCAEWin:

     

    In PCAEWin run the ROM, then stop it when you want to capture. Open up the debugger, and click the "->Line" button and enter 200 (you may have to do this twice to get a good screen.) Save a screen capture. Then click "->Line" button again and type 200. Save a second screen capture. Then open both up in Photoshop and paste one of the shots on top of the other. In the layer window, set the top layer type to "lighten".

  8. Atari70s: I think you may be jumping in a little too fast. Even the playfield demo requires that you have a pretty good understanding 65xx assembly. And assembly is VERY different from the high level languages you have experience with.

    I went into the playfield demo with quite a bit of experience programming Commodore 64 (6510) assembly, and it was still tough.

     

    My suggestion would be to get an intro book on 65xx assembly language. I learned most of what I know from the Commodore 64 Programmer's Reference Guide, which you can find on Ebay often. And there are many other books on this topic which you can probably find on Ebay or at thift stores.

  9. I just downloaded the program and I'm impressed. I think I may switch over.

     

    My suggestion is to add a few custom text fields that we can name whatever we want. This would add a lot of flexibility and free you from taking requests for new fields.

  10. Honestly, right now I'm planning on going with Hozer Video. Randy takes care of the orders and shipping which saves me more time and really makes $11 a bargain. I would consider the board w/ EPROM deal, except that I don't want to mess with shipping anymore.

     

    I am thinking about upgrading the label quality, though. I'm considering using an online bumper sticker printer to get my labels done. Looks like they'll cost $3 a piece 300dpi full color, and they should be about as durable as you can get.

     

    I've been just printing my manuals on nice-looking card stock from Kinko's using a good ink jet. Probably costs about $1 when you consider the ink cartridges.

     

    I don't really expect to sell anything close to 200 cartridges. Counting current orders, I've only sold about 20 Testcarts in four months. I expect to sell more of my Synthcart and Marble Craze game, but probably not more than 50.
