We have closed the loop.
The launcher can now assemble tal files on the fly, you can use Left to write #uxn programs, Nasu to make graphics, Dexe to include them into your projects.
That means you can have a complete workstation on a NDS, GBA, Playdate, etc..
Thanks to everyone who helped to put this together.
@celeste It's a little vm, I have a couple of notes on it here: https://wiki.xxiivv.com/site/uxn.html
Lemme know if you have any questions.
@neauoire question:
to get this working on gba, would need something like...
https://gbatemp.net/review/everdrive-gba-x5.489/
...be a place to start?
(have been lurking on uxn / Merveilles from my original account @eryn, and want to offer my partner their beloved gameboy advance with this beautiful workspace for them to try out the graphics stuffs)
(superclueless regarding...how to actually get going on the hardware in our beloved unused tech drawer with this wild wizardry you've wrought here.)
(absolutely spectacular curation and development of this, truly, this is a beautiful and inspiring domain you've cultivated into existence...)
(...and also, is there an "absolute-zero-to-running" guide for this somewhere? it feels like i need a level for mere mortals when understanding y'all Merveilliens' tech... ^_% )
@bd @neauoire @eryn thank you so much, I will ping y'all when I run into trouble...or success!
This is an amazing conglomeration of awesome with a side helping of neat & necessary...every time I can make a device return to usage after being abandoned to the drawer...it feels really good.
Thank you for loving that, too!
@celeste pico-8 is a fantasy console, it's a program made to look like a an old console.
Uxn is a virtual machine, so it runs everything through a little virtual cpu with 32 instructions. Porting uxn for example is only a matter of porting the emulator, porting pico-8 means porting a lua compiler.
@neauoire
I obviously understand the difference between PICO-8 and Uxn (particularly in intent) but porting a Lua interpreter is not significantly harder than porting Uxn, it's pure ANSI C and is meant to be ultra-portable just like Uxn. It'd be the rest of the large internals of PICO-8 that'd be difficult to port (especially since it's proprietary and impossible for anyone to port themselves :P)
@neauoire So, this is where the positive feedback loop starts, allowing ascension to the nth plane of existence through sheer machine wizardry, I guess.
Jokes aside, that is really cool to see.
Would it somehow be possible to swap the loaded launcher for an edited version too, as a kind of in-place hat trick?
@neauoire oh, let me rephrase the question, then, I want to ask about even wider self-modification
if someone wants to modify the launcher.rom -without- restarting the external emulator with a different launcher.rom, could the launcher be written in a way that would allow it to modify its own source to be replaced by the edited launcher.rom (while still in emulation), and transfer execution to the modified launcher.rom?
@neauoire damn, I did not expect that, I'm not sure how much cooler this can get (although I hope it will!)
I'm still waiting for an idea to pop into my skull that only makes sense in uxn's environment (come to think of it, has anyone tried to implement a secure way of communication between machines, or is that seen as less-important to the ethos?)
@nleigh it.. well, I should probably implement some sort of location handler so I could navigate in and out of folders, but I haven't gotten around it to it yet.
Ideally someone will implement a mini OS(something like DOS) on Uxn someday.
@neauoire Ooooh...
Now I kinda want to play with this again.
Last time I tried, I was trying to make a minimal assembly file that would do something simple, I think writing something as output or messing with the screen, because I wanted to understand what was *actually* going on instead of just blindly relying on the boilerplate. But I couldn't get it to work; I was confused as to why and in the end, I gave up before getting deep enough to get past that.
The uxn thing has also inspired a few idle daydreams around possible OSes or OS-like systems which I've also, predictably, never followed up on. Admittedly with kinda different architecture/goals though.
@neauoire wow! complete uxn ide!
before that i was thinking about assembling one rom, that assembles another rom, that can be edited to assemble the third rom, the third one being target rom you wanna develop. silly.
but now it's like a (almost0 self-hosting thing, that's great!
