I started a Twitch channel about NedoOS development (in Russian): https://www.twitch.tv/alone_coder
The first two broadcasts weren't saved (bug in Twitch Studio?). Here is the today's one:

Interesting! Although the commentary is in Russian, the auto-translated captions are just about understandable. I got the impression from the development video that memory is fairly tight in the kernel.

I wondered how many levels there were altogether in Untangle, so I looked at the source. It seems like it's going to take quite a while to get through all of them.

[Alone Coder]

In theory, Untangle has infinite number of levels, they are randomly generated In fact, all levels since level 21 will have 255 vertices in the mesh (all the previous levels have 6,10,15... "triangle numbers" of vertices).

In today's stream we made one more speedup in collision detection in Untangle, so I might pass level 21 in the future:

Surprisingly, Lord Vader made one more speedup in collision detection. This matters a lot at higher levels, because the number of vertices grows as a square, and the number of checks grows as a square of number of vertices, i.e. like n^4.

Levels 17-18:

Today's stream (the viewers became active at last ):

In a series of streams, I added a windowing system for menus in Scratch (labels, buttons, flags, edits, radio buttons). DimkaM added possibility to upload and start programs remotely (they are also auto-closed if you upload the same program), as well as to play music and show pictures.
On task close, its files are closed and its music stopped.
OS_GETSCREENPAGES is finally removed.

In another series of streams, I added pipes and primitive ANSI terminal, and commands like "dir >file" with stdout changed to file.

NedoOS can now be remotely controlled over Telnet! (well, over raw TCP in fact )

DimkaM solved level 18 of Untangle, and there were bugs in level 19 and on (now fixed).
Telnet server now works as indended.
Separate local terminals keep their screen and work well independently.
In the latest stream, I also showed several multicolors for 128K and how to convert gfx for them.

[Alone Coder]

Started streaming the game engine development. I added a character which can run & jump, added a tracking camera:

Taking objects, adding sounds.
In the end, Wolf 3D engine handling is described in detail:

BTW Telnet already works (tried PuTTY and Hyperterm). There is also scrolling ability in the terminal and mouse and simple copy-paste feature.

I hooked up a real ZX Evo and tested all the devices I have:

Contents:
Legendary Pentagon 2.666LE
Wolf 3D, scrolling game engine
Updating ZX Evo firmware and ROM
TurboSound FM

NeoGS
Test ZXNetUSB
NedoBrowser
NedoDemo 2 (TurboSound), switch off 60 Hz, secret options in Evo Service
FM part of my TurboSound FM is dead
Telnet client
Started to code "more" utility
Several old demos for colour per pixel mode
The Board demo (realtime 3D)
Супер Марио
Started to code "dir |more.com"
It works

I also streamed about the game engine. Enemies appeared, and they can be kicked.

Bullets added, they collide walls but do nothing yet.

[Alone Coder]

Bullets now decrease health and kill enemies, they drop through floor when dead:

NedoOS is rewritten for scrolling terminal, you can even copy and paste in it.
cmd now supports commands like dir > filename, dir | more.com, more.com < filename. Full documentation for API is being written.

In the recent streams I ported Turbo Pascal and BDS C Compiler into NedoOS.

[Alone Coder]

Streams are moved to YouTube.

Added gfx library for BDS C.
Total speedup of term and stdio.
Long names included in cmd and Nedovigator:

The game engine is abandoned because of no feedback.

[Alone Coder]

I fixed q1 game (network shooter deathmatch, originally for AY-based LAN) for ZXNetUSB, so it can play over Internet.

So, now we have two realtime net games in NedoOS.
