  1. Getting an email from David Crane just now telling me about Circus Convoy? Next level awesome.
  2. Great work here Dave. You have the talent, just a few more 'bits' (hehe) to go.
  3. Seeing you guys play the game was awesome - and in great company too. You’re right in figuring the palette for the low end of town. Stella and Javatari.js were relied during testing and these do align your Stella test. Seeing real world play such as yours is invaluable and reminds me of the variable circumstances growing up in the environment (PAL in a small country town, Australia). Dot crawl, brightness-contrast analogue controls only, ghosting, RF connectors with masking tape on leads up to bunny-ears aerial, Interference patterns from, well, everything … ahhh! Working on something fast and arcady for the next attempt (scrolly detailed pattern parts are in but having this conversation just now with the kernel about more bits and more bits, little things required now like sprites, you know … conversation fair to middling. Did grab a lighter palette this go round, so far digging it).
  4. Chalk & Duster Welcome to Chalk & Duster, that most recent entrant into the rapidly increasing genre of chalk and duster games for your Atari 2600. Gameplay You are a piece of Light Chalk attempting to re-shade a board of drawings - these continuously faded by Duster, a remorseless adversary who will stop at nothing, except maybe, a disappointing code bug I’ve yet to discover. Anyway, get hit and you’ll lose a piece (that’s the adversarial part). Lose three pieces and it’s curtains. Chalkless curtains. Duster also wins any game by moving left-to-right across gray-most drawings. You’ll know these kind as they don’t exhibit any banding. To figure how close Duster is to winning, note the frame which progressively fills on the front panel (diagram below). The other way Light Chalk can lose is becoming worn down. After becoming short you’ll wear down again - to nothing. Control the Light Chalk via Joystick using Up, Down, Left (when on the Board) & Button. Living on the Ledge Located directly below the Board is a Ledge (yes I’m going to keep with this capitalizing thing) comprised of two lanes which you zoom along, left-to-right. Light Chalk is opposed by Dark Chalk. You knew this was coming. But did you know it’s actually a game of Chicken? Dark has one move up its sleeve - choose when to swap lanes once per screen pass. Now, do you hold your lane or do you swerve? Light Chalk can swap over and over, bouncing between lanes. And it is bouncy as releasing Down on the joystick springs the chalk back up. Being hit by Dark smudges away your Light delaying you somewhat, whilst making screen passes (wrapping a screen) 'unhit' successively brightens your shade. After many passes though your chalk shortens regardless of shade. As a short piece of chalk you’re fractions away from losing the piece altogether. When you’ve had enough of the ledge, hit or hold-down joystick button to fling onto the board. If you’re the hitting-button kind of player, time it so that your chalk is beneath the Engagement Line when on the Ledge. Otherwise just hold until Chalk makes it to this area and it will automatically relocate you. Engagement Line On the Board is the Engagement Line which is either amber or green. Amber signifies your chalk is not the brightest. You may still go ahead and use Chalk but know that you won’t get any points. Why use it at all then? It may save a drawing from becoming too gray thereby denying Duster its progress; your Chalk’s shade directly relates how a drawing row will re-shade. Or you may want to race across the Chalk Flecks below the drawings to re-lengthen your chalk. Chalk Flecks are situated along the lowest row and are shade-controlled by the row immediately above it, meaning that for Chalk Flecks to re-lengthen your chalk this immediate row above must be full brightness. Similarly, Duster cannot gain advantage by rubbing along the Chalk Flecks but can still wipe out your chalk. And it can, of course, fade the flecks via the controlling row. Remorseless, I’m telling you. If the Engagement Line is green this signifies all is well with your brightness and you may proceed to the drawings above to potentially score. Scoring is located top-left of the screen, which is also the current Level. On the top-right of screen is the Vertical Gasser Group indicating how many chalk pieces remain. They progressively fill whenever you score. Once full you are proceeding to the next level, like it or not. Golden Line Situated above the Engagement Line is the Golden Line. This is a score doubling bonus declaring which row should be brightened. As expected, the bonus is only applied when you’ve scored, meaning a Golden Line is no advantage to any re-shading other than brightest; rely the Engagement Line to help you out with this. The Golden Line moves in accordance with your screen passes along the Ledge. Note how and when it moves. Drawings from top row down : 2015 Mercedes-Benz G63 AMG 6x6 1981 Trabant two-stroke 1977 Toyota Land Cruiser BJ 40 2011 Mitsubishi Fuso Fighter 9 Tonne Observations ... Light Chalk, as brightest, can choose to go across the same row each time collecting points even if that row is already fully bright (hey if it works for you why not?). Sacrificial Chalk : You are rewarded due points on a row even if the Duster gets you mid-draw. As levels progress : Duster becomes more efficient. Duster quickens (from levels : 4, 8, 16 & 32 - all the lovely numbers you’d expect). Board color alternates. Chalk auto re-lengthened. Game Over is declared through a Good Game, ‘GG’, located in the Game State panel.

  5. Thank you for the include & analysis! Very helpful.
  6. Thank you. Your suggestion is solid. A neat way to wrap the thing together. Is possible in 4k … Predictably, I spend an allowance too readily on graphic effect and what passes for an AI (!) Guessing I’m 12 months from doing something decent for the 2600. Reviewing code, I’m wasting cycles & bytes on mumbo-jumbo logics which could be trimmed for the same outcome. So though I say yes, it’s done, is also another sandcastle here along a journey to building something of lasting value.
  7. Really useful, thank you for the release.
  8. Chuck Heads A game for 1 or 2 players. 1 player Move Blue Chuck down or up using the joystick. Use trigger to select a head when holding ball. Each head defines a different kind of chuck : Cool Chuck chucks a Googly Crazy Chuck chucks a Jiggler Cheeky Chuck chucks a Flapper Ball releases when the color timer alerts green. This is a horizontal band located immediately below the playfield. Timer rotates through a sequence of ambers-to-reds before each chuck event. If holding a ball, player aims at the Blue Zone - eight vertically aligned blocks on the right screen side. Striking anywhere within, including gaps, rewards a point. The computer plays Red Chuck and only needs for the ball to reach the left screen side to be awarded two points. Either Blue or Red Chuck can catch the ball, preventing point addition for the opposing head. Every three points for Blue Chuck moves him closer to Red Chuck. A red metallic guard behind delimits the playfield everso for Blue. The guard’s reflections of Red Chuck help discover where to sit for a potential catch. The first player to twenty-five points is the winner. Reset to toggle a new game. 2 players Additional to above rules, you may co-op Red Chuck using a second joystick. The computer controls movement and head selection, player opts to trigger the chuck. Stella original release Chuckhds.bin **Update : 2020.11.11 : Cartridge Labels targeting the NTSC release.

  9. There's a lot to like you know, not too much longer before all is tidy for release.
  10. Made it to the Room o' Many Ghosts ... no boasts.
