Default How'd They Do That: Cracking the Code (accepting topic requests)

So. I'm almost done with the thing I'm currently working on, and I think I might want a new project to work on. I've had in my head the idea of doing a series on explaining how stuff works with respect to computer code and video games in particular. Those of you who have read my Anatomy of Sonic know every 2-3 posts I spend time digressing into technical discussion about under-the-hood operations the game uses to do the things it does.

Basically: I want to do more stuff like that, and I want to be able to make it into a video series. The only problem is right now I'm still looking at ideas for episodes. I have a couple of my own, but I want to hear from people about the sort of things they saw in video games that made them think, "Whoa, how'd they do that?!"

For example:
That rotating room in Castlevania IV. It's Mode 7 but it's not just a flat perspective change. How'd they do that?
The dungeons in Phantasy Star. 3D FPS movement on hardware from the mid-1980s? And it's so smooth! How'd they do that?
NES scrolling. Early NES games could only do scrolling in one direction at a time, but look at Super Mario Bros. 3. How'd they do that?

I probably won't be doing a video about, say, transparency on the Saturn, because there already is a pretty thorough video on the subject, but that's similar to the tone and level of detail I want to reach here on this series.

Along the way we'll learn about cool stuff like affine transformations, the differences between ROM and RAM (and other types of computer memory), scanlines (and how a copy machine works), framebuffers, perspective (and convergence), and loops.

These will probably take a while to make, so don't expect anything more than a pretty sporadic update series (like, I might be able to do one every couple months), but I also want to try to be thorough, accurate, and easy to understand.

SO. I'd love to hear what sort of cool stuff people have been curious about. What do YOU want to see in this series?

I know a lot of the basic stuff, but I'd be totally up for learning about Mario 3's multi-directional scrolling tricks. (The caveat is that I hardly ever manage to make time to watch in-depth videos on anything. But if it's not too long I'll try 'cause this shit is fun.)

There's some stuff out there on these subjects but a lot of it is someone guessing about what's going on. The good stuff (IMO) is when they start peeking at the data in an emulator and figuring out for sure what's going on.

I definitely want to get to doing that sort of thing as much as possible

It would be nice to see how the NES hardware translates into colors and sounds. I know it's probably the same as PCs, but I don't really know how those work either.

But if you want to stay solely on the software side... I'm afraid I don't have any good ideas 8))))

Anything goes. Hardware, software (software is probably easier to discuss), you name it. I want to keep ideas open as much as possible, but I can't promise I'll be able to do everything.

Any interest in picking apart the inner workings of some complex glitches?

You could do an entire series on how Treasure was able to get Mode 7 style scaling and rotation in all of their Genesis games.

Sure, any you had in mind?

And yeah, stuff like Seven Force is in the docket too.

I remember hearing how they actually calculated the physics for throwing objects in River City Ransom. I am curious about how that worked.

I'm not sure I know enough about the subject to know what's impressive or interesting. Maybe that's a good place to start - build your viewers up from the ground so they can appreciate the cool stuff?

I'd be very interested in the evolution of draw distance rendering in consoles.

I went ahead and made a quick little theme song. Also I'm calling this "The ROM Bank Show" now.

the brits on the forum will get it
