@waporwave will do -- I'll add another a technical notes document to the FAQ when the design has settled down a bit.

@Ronflaix @fsouchu Ha, that would be nice :) Maybe I should consider giving the filenames a better extension than .sfx

I'm really hoping to make userland mod/xm players at least theoretically possible to implement without having to manually render the raw audio data.

Don't you sometimes wish you had a little fold-out nether desktop that is accessible from anywhere?

While using the picotron code editor, the tooltray is pulled down a little to reveal a handy desktop area. A file called snippets.lua is opened in the code editor from here.

@fsouchu no, it's a SID tune that happened to be playing! (I posted a reply with the link)

I find it most useful as a place to keep file shortcuts, but you can also run widget apps there and use it like a dashboard, of course.

too many knobs

@luchak @waporwave @fsouchu I did actually take out some knobs for this screenshot though :D

How to make a 999-byte vectory racing game in 8 easy steps..

  1. Start with a flat plane. Loop through a grid of points (x,z) infront of the camera and calculate an elevation for each one (y)

  2. Perspective projection: draw each point at x/z, y/z (z means "distance from camera")

  3. Alter y according to sin(x) and also use that for the colour of line segments joining the dots.

You're in business.

Visualisation of generating a flat grid, and then elevating each point according to sin(x)

  1. When drawing a point under the player, remember the result of that elevation calculation to figure out where the player is going to hit the ground.

  2. Clamp the y value of the ground to create flat sections

  1. Add noise to the y values based on sin(x) and sin(z)

  1. Make the track wiggly by adding an offset to x in step 3 that changes with z (more sine waves)

  1. More parameterization! More sine waves! Here are some parameters called "gully" and "canyon" that control the clamping y, bumpiness and wall height.

  1. (bonus) Finish drawing the owl. The janky physics is based on gradients along x,z also grabbed from the drawing pass. Click on 'code' below the cart for some extra info: https://www.lexaloffle.com/bbs/?tid=54397

@fsouchu haha -- yes, some folders that need to be in a fixed location (/system, /desktop) are flagged as unmovable.

But even so, everything in /ram is generated on startup (and /system is reloaded from ROM by default) so even if the session gets borked it is usually only until the next reboot.

Dear fam, check around the web for your games. I was just informed that someone submitted Downtream Dream to http://pog.com and http://y8.com and appears to possibly have been monetized.

The WHOIS for both implies they're run by the same ppl, does anyone know more about these sites?

@ridgek Yikes, it was indeed broken. Thanks for the heads up -- it should now open the cart's home thread in a new tab.
