Creating an Operating System for the NES

[@BalancedSpirit79]

This reminds me of the Contiki project. They wanted to make an NES able to surf the net and they were going to use the Zapper as a “mouse” but the project was never finished. Thank you for doing all this work. Making retro systems do great things in modern day is always fun. “Everything old is new again.”

@@mr_indie_fan Oh I have that faved already; that was insane!! :D

[@mmazurr]

I'm really curious how that zapper thing would work. As far as I'm aware, the zapper doesn't actually "point" at something. It just checks if the place it's pointed to was the place the screen designated as "correct", which is why the screen flashes when you play the game, as the game is telling the zapper where the duck is. Maybe they could come up with something clever or maybe it didn't work out too well. Frankly it seems more difficult to get an NES to try to render HTML properly, and forget about having it interpret CSS or JS. Just HTML is pretty light, but still potentially too much for the NES to handle.

use the floppy to run dos OR make a mod for family basis where you can save stuff to a floppy (like a commodore 64 or smth)

the hardware of the FDS can be modified to allow for unrestricted disk rewriting but I don't know if emulators support that. it would be limited to only a portion of the disk being writable. I suspect a more compatible solution would be some kind of bankswitching in NVRAM

Translated by ChatGPT. In China around 1995, there was a NES-compatible console called the "Xiao Ba Wang Learning Machine." This machine indeed came with an operating system that included a Basic language environment and supported disk-based file operations. Additionally, the system featured game programming, typing practice, file management, and other functionalities. Thank you for bringing back these memories.

[@tnomad]

This is a cool project. To be a bit pedantic it's not really an OS, it's really a GUI text editor. For it to be an OS I think you'd have to either have to expose some kind of API to make additional apps that run within it or find some way to load in and execute games, which I know the latter would be quite difficult. That's not to diminish that it's an interesting project and a good video explaining some of the technical issues of working on the NES.

[@InkboxSoftware]

You're right that it's not quite an OS in the sense of not having an API for other programs to use. But I think it wouldn't be that hard to include some way to have games as well (they'd just have to built into the program). The way the "apps" of the system work is when the user clicks on them it only runs that section of code, so it wouldn't be hard at all to create a game and then place an icon on the desktop for the user to launch it. Even including large games wouldn't be hard because I've actually written this program with the MMC3 mapper (a bit overkill for what I needed) so even if the game required two full pages of CHR ROM you could just switch to the game's section when it launched. To be honest it never occurred to me to write a game into the system (instead I was debating whether or not to build a spreadsheet app), but I think that would have been a nice improvement to the system. Loading games could potentially work with the use of the Family Keyboard's Cassette reader, or using the Famicom Disk System, so it wouldn't be impossible.

[@XAWZ]

@@InkboxSoftware It would be neat if as a built in game you included a "port" of one of those old LCD Game & Watch games. Weather that's possible or not, I don't know. I'm not a programmer. Or Tetris would be cool too.

[@jadeglaze3390]

Super cool project! Here’s a relatively straightforward compression idea for your saved files: Since your alphabet is only 64 characters, you only need at most 6 bits per char, not a full byte of 8. This means you can store an 832 char file in 624 bytes with some bit shifting and masking. That’s 13 files in 8kb! And that’s keeping it relatively simple. If you want to really stretch your 6502 chops, you could implement Hoffman coding compression and allow variable length files (just have the first two bytes or so - technically 10 bits is enough- be the file length). Or a compromise: more compact than fixed 6 bytes per char but simpler than full on Hoffman coding: make a predetermined variable length encoding- like a precomputed Hoffman table or something similar to UTF-8 but alternating between 4 and 8 bits per char instead of 8 and 16 bytes per char.

[@jadeglaze3390]

Wait! Better idea for variable file size: the first few bits of the file should represent a length in _chunks_ that the file requires where the chunks are known size. So for example: first 4 bits of the file represents the number (1-16) of 39 byte chunks (16*39=624) that the file occupies.

[@kargaroc386]

Yeahhhh but the 6502 would probably choke on any of that stuff. It would work but would you want to use it? I guess when the platform is 8 bits the answer is always yes

[@greenaum]

@@kargaroc386 I see OP's point about saving 2 bits, it's an idea worth considering if this were a serious project and you wanted an ALL-CAPS word processor for the NES. It'd need as much space for docs as you could get. Huffman compression is something else. Certainly 6502s can do it, and did, back in the '80s. But it's a pain in the arse to get your head round and you wouldn't want to have to debug it. Depends how clever you are. Really though you can't just have all-caps. There must be a way to extend the tile table. Games did it, although often using scanline interrupts which wouldn't be suitable when you'd want mixed case in all the text. Maybe try something clever using sprites for the extra letters? That'd get complex I think and you'd have to do it on the fly. Then again the ultimate Atari 2600 hack turned out to be having a cart that bangs hard on the machine's data lines. You set the data lines to high, I think, and the cart can drag them down to 0 with enough current. Yeah I doubt it's good for the old gal but maybe they built 'em tough back in NMOS or whatever. They drove the graphics chip hard and got more sprites than you were allowed out of it, looked amazing admittedly and could have been done at the time. But I wouldn't wanna be the guy i the shop when your cart breaks somebody's Atari and there's a queue of them lining up all with the same problem. Sorry what's the moral of the story? Abuse the hardware? Sometimes that worked out well.

Computer operating systems have existed for the NES/Famicom almost since its debut -- the original Family Basic from Hudson Soft, and the many unlicensed "educational" Subor/Dendy multicarts which included (versions of) it later on (FBASIC, GBASIC). I've been meaning to translate "Bravesoft Windows 2000" which is one of those, and has several apps. There is some graphics compression we've had to undo first. People on KZbin have dismissed the Chinese/Russian NES Windows "knockoffs" as non-functional, but they're not. A lot of the "functionality" is fake and just for show, but the applications are not -- and include takes on Word, Excel, DOS, and of course Family Basic (and its background art program, message board and music programs). And so on. Some of the later carts do a decent job of being an 8-bit computer, albeit in a style which was 20 years out of date at that time. Homebrew Family Basic programs were published in magazines at the time, and Gaming Alexandria has been trying to preserve them lately.

The NES has only 2 KB of RAM, which is a severe limitation. Although most of the data can be stored on ROM, an OS needs a lot of memory for variables, hence why 2 KB is not enough for a GUI OS, and also why this not actually a full OS, but just a neat proof of concept.

A little known fact about the Nintendo Entertainment System is that, due to the system's ubiquity, there was a time in the 80s when, since very few people owned computers, there were plans to release office software for it and, at one point, even an entire operating system. Gordon "Sting" Sumner of The Police, a group that had at the time come into a lot of money, invested heavily in the latter project, reasoning that eventually this (or an OS like it) would be used to create music. Nintendo of America sent their top investors copies of the software to try out, of which Sting was one of them, but the product never made it to market. To this day, the operating system was thought to be lost media. Nintendo had a habit of deleting their source code at the time and do not have a copy of the software they wrote. More recently however, it has come to light that Sting still owns one of the cartridges and, working with the emulation community, has made plans to release it to the general public. He's sending out a NES OS. Sending out a NES OS Sending out a NES OS Sending out a NES OS Sending out a NES OS Sending out a NES OS Sending out a NES OS Sending out a NES OS (I apologise for nothing. I saw this joke years ago and, having found no trace of it on the open Internet, rewrote it from memory.)

Alternative typing method: Holding A makes a cross representing the control pad appear. The four directions are labeled "Upper case, Lower case, numbers, and space. Pressing the direction for space is obvious but pressing for example lowercase replaces the labels with the alphabet broken into three "ranges" with the fourth being a "go back" option. Going into a letter range breaks down those letters into three sub ranges and finally three letter options to print. The Upper case and numbers work the same way with numbers also including symbols and punctuation. It sounds complicated but I had a smart watch app that let me text like this with only three buttons and you get used to it really quickly and can type much faster than traditional control pad typing methods. So for example a lower case A would be Left (lower case), left (A-I), left (A-C) left (A)

What a legend only one ad in the beginning . Your so damn underrated

[@finkelmana]

What a complete waste of time and effort for something absolutely useless and serves no purpose at all. I love it.

[@Plumjet09]

Congrats on 1K!

Write a simple modular open source kernel and userspace for the Famicom Disk system with a very simple display manager and file hiearchy, something more linux/unix like. theres a disk to store things on, a virtual nvram possibly on the disk, etc.

I wish the SG-1000, Master System/Mark III, SNES/Super Famicom, and Genesis/Mega Drive had operating systems too.

[@ChosenOne41]

Maybe in the future you could do this on the SNES and have mouse support

[@entercheesynamehere]

It’d be cool if you could load this onto a physical NES cartridge to be able to use it wherever

[@Diamond_Tiara]

the original NES was designed with a keyboard and as being a home computer akin to Commodore, Atari, Apple and Amstrads. Which ran OSes. Just lack of RAM but since it's based on 6502 you can, I also thought you've ported GeckOS onto it. Still trying to find a way to use my 800XL and its amazing mechanical keyboard as a serial terminal to control my linux machines.

I have no idea why I'm watching this, but the Arthur interstitial jingle @1:27 won my heart over

[@BeanyBeans]

The kanji was cool, but I think got pal releases and USA, the English logo would've made more sense. I don't wanna say it would look better, because the kanji looks cool and you're the guy that made an operating system for the NES, but just a thought I had

[@jamesfloyd6693]

it's like over complicated post it notes. I love it

[@bwc1976]

This is so cute! I was going to add that the Japanese Famicom did offer a disk drive, but someone else already has.

[@dim7ay]

You could save some space if you didn't copy the whole screen data into a file but only the characters (like a txt) and use a simple compression code. also you could add a pixel art program too, using one 8x8 tile as a pixel. still, very cool project!!

[@Mysdia]

You could look at cartridge Expansion RAM up to 1 Megabyte to extend the size of data the word processor could use. Also... what about Printing documents? Hmm

[@WSNO]

This is brilliant. Would love to see this idea expanded upon and to see a cartridge i could run on my own NES someday

[@Captureman]

Thank you for experimenting with the NES. I love what you do!

[@therealsnowwhite1937]

Reminds me of those mock OSes that come with Famiclones mimicking that of Windows 98 and later.

[@CableWrestler]

Congratulations for hitting the algorithm 💪🏻

[@Strange_Armour]

This is - beyond a doubt - a true testament to the power of boredom. Kudos 👍

[@ontoya1]

I'm neither a programmer nor have ever played in NES and I think this is super fuqin badass and your channel is really fuqinnderrated even though I understand How niche a concept like this is.

[@sdjhgfkshfswdfhskljh3360]

This video made me think about what criteria can be used to separate operating systems and regular programs.

[@hyakin7818]

Did you know the famicom over in japan had a pc conversion add on giving you a keyboard and a cassette drive

[@SpencerYonce]

This is the coolest thing I’ve seen in a long time

[@honzapobisCZ]

That Lunar Ball music is just forever imprinted in my brain :D
