Uxn4's firmware running on my Kobo Woooo!

Good morning. I'm continuing to work on my #xteink x3 #uxn reader vm & firmware.

I updated my branch to have it load the uxn rom from sys/firmware.rom if present, or fall back to the built-in rom if not. So testing further updates on the device won't need further flashing.

Now working on handling font selections.

Fonts from the SD card are working in my test roms now. #uxn #xteink

I've also made good progress on the reader rom for the x4 pro. I'll start on the vm port later this week or sometime next, after I wrap up the current projects.

For everyone who asked me for a #uxn firmware for the XTE INK 3, @crc ported the Varvara emulator!

What's the state of firmwares for the #XTEink machines? I'm loving the formfactor and lack of touchscreen on mine so far ...

They have their own default, there's CrossPoint and Papyrix, and do we also have a full #uxn that I could run 'anything' on?

It's not done yet, but I have a variant of the uxn4 vm running on my xteink x3 now. #uxn #eink

uxn4 running on the xteink x3 and x4.

Is there a way (other than spamming F1 for zoom) to launch #uxn applications with uxn11 in fullscreen mode? #varvara

thanks to @neauoire and their uxn4 project i can keep using my broken xteink x4, with just a few lines of mods to the upstream firmware!
ghosting is much worse than with a pristine screen, of course, but making refreshes more frequent helps :)

My first version of #uxn in #ilo is now in the fossil repository.

Released a firmware for the XTE INK 4, it displays text and draws pictures, and wait for it, it remembers your page. That's it, there's no other features.

https://asciinema.org/a/1267653 shows my #uxn in #ilo assembly running the drifloon assembler, building another copy (properly byte identical) of drifloon, then assembling opctest & tictactoe, and running both.

The uxn implementation is down to 2853 cells, of which 2k are used for the stacks & internal memory buffer for block i/o, so just over 800 cells of actual machine code. It can be built to either write stderr into the blocks or to just discard the stderr text (which is what I have set as the default).

I'll do a little more work on this tomorrow to tighten up a few things, but it's complete. Later this year I will be working on a #nga port, and will work on expanding the device coverage, but I'm pretty happy with it at this point.

I now have my #uxn in #ilo passing the opctest.tal tests. Time to finish cleaning up the instruction bundles & adding some comments so it'll be easier to maintain in the future.

It's not ready to publish yet, but I have a functional #uxn in #ilo assembly now.

Uxn has just drawn its first pixels on the xte ink.

As an evening side-quest, I've been writing a new firmware for the xte entirely from scratch in #uxn, this form factor is insanely cool but unfortunately, the company who makes this ships awful AWFUL disgusting software, making the device rather useless.

I think this is, as far as I can tell, the only firmware for it that's entirely written by a human. I've still got a ways to go, but I should soon have a new little uxn computer that fits in my pocket.

Real talk folks, is it ADHD when you are organizing your room, find a decrepit Nook that you previously hacked in the past to run #uxn Oquonie and decide impromptu to make some paspartú and frame it?

Learning #uxn is called "going down the Hundred Rabbits hole."

One of the first game we ever published for #Uxn was Donsol, five years ago, to celebrate, we've made a whole new version of the game with new monster sprites, better resolution and animations.

We had originally made it with the Playdate in mind, but they didn't want it so we're making available to play it directly in the itchio page, or via your favourite Uxn emulator!

We hope that you enjoy it.
Have a good autumn. :)

I know I shouldn't be surprised that it just works as is, but still cool, I can build compile uxn binaries directly inside dos.

Some days we have no power, others no reception, once in a while we have neither. Today was such a day, the oppressing low skies suffocating the signal and covering our solar panels didn't allow for much virtual fussing.

But while penciling out storyboards for our #Catjam entry, Rek pointed out that it might be nice to have a Yufo cameo aboard the train. Genius idea! Let's look at the actual state of that ol' thing.

Written in a haste during the Virtual Pet Jam a few years ago, its codebase was horrendous; Uxn was quite young at the time, the linter in its infancy too. It ran just fine but needed a bit of love if the codebase was ever going to be something worthy of being looked at by anyone.

So, I spent the little power I had left in my laptop rewriting it all in a more standard Uxntal style, with the typical video game OOP patterns that makes the more recent roms somewhat robust. It runs faster, looks and feel nicer too. I've published a new build with metadata and all the other niceties of modern #Uxn projects.

If anyone ever asks who that weird antlered creature on the train is, at least we can be proud to point to Yufo.

#occ2026

alright, i'm officially working on implementing a #uxn environment for 68k macs (system 7 specifically) for #occ2026

will this work? who knows! but it's something i'll be doing next week.

Someone just demonstrated that the entire Uxn toolchain can be reconstructed from nothing but a POSIX shell, xxd and sed. It's down to taking 34 minutes to build the Uxntal assembler.

I made a zine, it's called Fractions Are Everything, it invites the reader into looking at fractions a little differently.

The typesetting is done entirely in #Uxn.
