kodiak version 1 is done!

there are still some things i'd like to add later but for a #uxn solitaire game this is fairly complete.

splash screen ✔️
animations ✔️
automatic moves ✔️
music ✔️

Finally got around to rooting my Nook Simple Touch and trying the uxn port from @bd. Works great! #uxn

the #oldcomputerchallenge brings together not just machine freaks, hackers, or ascetics. Just idling in the irc channel exposes one to many hidden talents.

- Produce exactly 1 copy of itself
- Name the copy "4"
- Not execute the copied file
- Print, return, or display the number 4

I finally managed to release #uxnfloppy, my bootable x86 #uxn emulator

Try it out here: https://git.sr.ht/~gustav/uxnfloppy

I got wondering how much work it would be to compile s-expressions to #uxn, it turns out, not a lot.

As a test, I've only implemented `let`, but it's shockingly easy to map lisp-like syntax to the uxn assembly, I might push this further still.

I spent the evening analyzing opcode usage in UXN programs.

The most used opcodes are DEO2, JMP2r and ADD2. Almost half of all opcodes are never used in the 22413 LOC that were analyzed. The majority of unused opcodes are return stack variants ("r").

In the table below, the most used opcodes are marked in red, the least used in blue. Opcodes that were never used are shown in light grey.

I made `smolbean`, my own little #uxn #varvara virtual machine :3 It was loads of fun, and I tailored it to my Zaurus Husky!

There is sound, it's recorded from the headphone jack of the palmtop!

I'll publish the source code eventually!

Uxn implementers may also be interested in the subproject `uxn-cpp`: https://github.com/ar-nelson/uxnpi/tree/master/uxn-cpp

It's a port of the reference Uxn interpreter to C++. All of the Varvara devices (except audio, that's still WIP) have been converted to abstract base classes. This is an easy starting point to port Uxn to any platform; uxnpi is just a thin layer on top of it.

Uxn on the GPi Case 2W is finally usable! I have Fourtette (https://github.com/nf/fourtette) working now, fully playable! Though only at 1:1 pixel ratio and with no audio.

This is running directly on the bare metal of the Pi Zero 2W, using Circle for graphics and USB gamepad drivers.

My company had a Pi Day Hackathon, and the project I decided on was to run Uxn on a Pi Zero 2W. Specifically, on this Game Boy-style case, with graphics and controls working: https://retroflag.com/gpi_case_2w.html

It was harder than I expected, and it's still not done!

You'd think it'd be as easy as installing the default Uxn emulator on the Pi, since it already runs Linux. But the GPi Case has a unique driver for its screen, and only a few "retro gaming" distros support it.
