Salvo 2085, a 7800basic WIP game, update #1

Posted by RevEng, in programming, 7800 17 April 2014 · 191 views

Between working on 7800basic, recent MESS updates, and a few side projects, I've been also working on a 7800basic game thats an update to the old classic, Crossfire .
 
In its current state its a bit rough, with programmer graphics, preliminary sound effects, and just a few essential stats on a plain scoreboard. On the plus side its playable, the dif...


7800basic update #3. the woods are lovely, dark and deep

Posted by RevEng, 28 February 2014 · 279 views

The 7800basic 0.1 beta is now public .

It's possible to create games with 7800basic, but it's by no means finished. I figured I'd share some of the features I have planned, in no particular order...
some mechanism to fill those pesky DMA holes that I mentioned in the last blog entry. This isn't a particularly sexy feature, but not wasting 2k/4k of space...


7800basic update #2. powered by good will

Posted by RevEng, in WIP, programming, 7800 16 February 2014 · 299 views

Daniel Everett, a linguist who studied the Piraha - a small tribe of hunter-gatherers in Brazil - reported that while the Piraha know of food preservation techniques, they don't actually preserve any food for their own use. Instead, tribe members immediately share and consume their catch with the rest of the tribe, as a sort of gift economy. Preserved foo...

atari 7800, programming
For a few months now I've been toiling behind the scenes on a port of batari basic for the 7800. Today I'm going public and showing off a little bit of what I've accomplished. Since a picture is worth a thousand words...






...the source code for that quick and dirty demo is decidedly not a thousand words. It's 68 lines of pure 7800basic code, and...


Irata Anthem, sung by TIA

Posted by RevEng, in programming, audio, 2600 19 May 2012 · 373 views

One of my back-burner projects is a spiritual sequel to M.U.L.E, for the 2600. So far I just have a planet kernel, species+color choice kernel, and the beginnings of a theme. The game will be developed at my usual glacial pace, so I figured I'd share the theme, as it could be appreciated on its own...

I mentioned in my first WIP article that I have three criteria for evaluating a game idea.
  • Is my concept really technically feasible?
  • Is it interesting?
  • Is it fun?
These are sometimes tough to...

Posted by RevEng, in unix, audio, atarivox, 2600 04 June 2011 · 521 views

One of the easiest ways to create phrases for AtariVox is to use the PhraseALator utility. PhraseALator is provided free of charge by the folks who create the SpeakJet chip in the AtariVox, Magnevation.

Using a TTL level serial port, you can connect your AtariVox to your PC and pull it's strings from a nice point-and-click interface.

You can use...

stella's voice

The 2600 isn't widely hailed for it's luxurious sound.

The TIA chip, which is responsible for the sound of the 2600 as well as the video, was designed with fairly minimal audio capabilities. On it's own it has the ability to make fairly simple tones, rumbles, and white noise type sounds.

Similar to how you need to...

the ascent

Mountain climbing is an activity that can be done many ways.

Mountaineers may employ sherpas to assist, or they can choose to climb only with other mountaineers. They may set up base camps at which they have large amounts of supplies, or they may simply climb steadily, carrying a meager stock of supplies that must last the whole...

    "Time it was, and what a time it was, it was
    A time of innocence, a time of confidences
    Long ago, it must be, I have a photograph
    Preserve your memories; they're all that's left you"
