Impossible Mission (legally distinct from its extremely obvious permutation) was one of the more popular games on Commodore 64, and I think it still has its charm. I think the mechanics like basing floor detection on the position of your foot, and the unadjustable front-flip jump, make for an interesting game design study.| dansalva.to
In my opinion, an understated programming skill—one that only comes with experience—is knowing when to be "good practice", when to be clever, and when to be dumb. Today, we're being dumb.| dansalva.to
Apple Vision Pro reminds me that computers have become too efficient. I'm currently typing this blog post in a floating window in the middle of snow-covered Yosemite. I am a floating body manifested into the transcendental Tim Cook matrix. I look into the sky and follow the soft clouds as they pass overhead. They slowly part, revealing Steve Jobs' smiling face watching over me from the heavens above. I am merely one more thing.| @dansalvato
In 2011, I was selected to be a part of Google's Chrome OS Test Pilot Program. I received a free Google Cr-48 laptop, and it was an absolutely charming machine. The rubbery, matte-black chassis had absolutely no branding anywhere on it. Upon opening the lid, the system would boot into Chrome OS, which, at the time, was literally nothing more than a fullscreen Chrome browser—no desktop, no apps, nothing. I used the Cr-48 throughout college, often as a thin client that would connect to my des...| @dansalvato

Earlier this year, I had to figure out how I was going to load level data into Magicore Anomala. A level contains backgrounds, sprites, animations, dialogue scripts, and much more. Ideally, I want to pack all of these things into a single file, so that I can deal with the filesystem and file names as little as possible. I did some cursory searching on tools or frameworks that make it easy to define and build custom file formats, but the stuff I found was a little too complex for my use case, ...| @dansalvato
If there was, it would be spelled "Assemblify", which is now the name of your next startup. So, the cool thing about Assembly is that whenever you perform an instruction, the CPU runs a bunch of comparisons automatically! They are stored in "condition flags", which you can use to branch (goto) or do other stuff if the right conditions are met.| @dansalvato
I came across a cute little trick while looking to optimize my physics routine in Magicore Anomala. In the routine, I need to check if each object is inbounds, and deactivate it if it goes out of bounds. Pretty typical situation, and we'd probably see it written as something like this:| @dansalvato
Magicore Anomala is powered largely by the Amiga's blitter, allowing me to quickly clear the screen and draw hundreds of objects every frame at a full 60fps. It runs in parallel with the CPU and excels at copying or manipulating large blocks of data. But the blitter goes above and beyond the functionality of simply hauling bits around. You can shift, mask, and logically combine up to three independent sources anywhere in shared memory. Today I'll show you how Magicore uses the copper and blit...| @dansalvato
One interesting challenge when coding the game engine for Magicore Anomala is figuring out the ideal data structures for different scene objects. Since we're on a 7MHz CPU and need to process hundreds of objects per frame, every CPU cycle counts. Here are the requirements for the bullet objects:| @dansalvato
I recently redesigned the Team Salvato website, moving it away from WordPress (thank goodness!) and into a static site generator, which I feel is appropriate for the content it serves. (I reused a lot of it for this website, because I'm too lazy to come up with something different!) When thinking about a mobile layout, I decided that I didn't want the typical "hamburger menu" icon, because I was never a fan of those myself—I'm not sure why, but I always feel a bit bothered for site navigati...| @dansalvato
