Big thanks to Eduardo for giving a micro-talk on his Try Omarchy project at our rl monthly meetup in Kyoto last night. but also... sharing that he's played Growtopia since he was 11 and some various uh, technical tricks he did with it

Oops, will check that, thanks. About alignment tools .. uhh.. coming soon. (you like the ones on the right of this pic, right?)

update: actually in battle it' s fine, my complaint stands but I guess there are kind of two modes, depending on the area/activity

Trying to put my (literal) finger on why Wolverine's controls feel so mushy. I think part of it is it can randomly take up to a SECOND to actually run after pushing the run button!

Very early engine test of a new game I'm working on! By the way, did you know the best thing about being indie is being able to put yourself (and actual building) into the game? I mean, they say to make what you know... (unnamed, but will be psychological horror)

Astra's visual understanding is next level. bought four dog lights and THREE already have broken clasps. From images (and a few measurements) it was able to create a working 3d printable replacement

er, *streaming, rather. Ok, I've tried DeepSeek-V4-Flash-Vision-Exp, Qwen3.8-Flash-Next and GLM-5.3-Flash and we're still 0/25 on winning an infocom game. Ending the experiment, will try again when local LLMs improve a bit more...

I'm steaming now! Help me test out gamebot, an all local AI that tries to beat infocom games. (it listens to chat for help, I'm sure that won't turn out badly) www.twitch.tv/rtsoft Planning to leave it on a few days

3ds support (using a modified Azahar) coming to HoloVCS's github soon! (runs on Looking Glass 'holographic' displays) - I've introduced a new "mode 2" especially for this, it's pixel accurate, works much better than the 'diorama' method I used for virtual boy/nes

Playing Zelda on a $99 Looking Glass Go 'holographic' display. Big thanks to @LKGGlass for open sourcing their Unreal plugin - got it updated for Unreal 5.8 and hyper optimized for my project. (100x faster quilt rendering!) github.com/SethRobinson...

Also, it appears ALL old Growtopia/ProtonSDK builds (pre July 2018) insta-crash on modern NVidia cards due to a dumb bug I made (I didn't expect OpenGL extension lists to be > 10KB in size). Oops. Worked around it by hacking the exe.

Seth A. Robinson @rtsoft.com · 20/08/2026
Ha, found an ancient Windows build of Growtopia from November 11th, 2012 (Buildo.exe) labeled "V0.01". Can't actually play online with it, I tried :D That slightly disturbing text on the about screen survived until 2018 I think (?)

Been organizing and cleaning... surprised to find FIVE GeForce 1080 cards in the closet. Built an open 'bench machine' with mostly old parts (spent $300 for new MB+CPU) to make testing easy so I can sell 'em on Mercari. ($80-$100 range?) Old, but still a capable GPU.

Hmm, absolutely doable. We'd get hit with downsides like losing access to native fonts, memory limits (matters for undo on large files), possibly slow loading/initialization, no legacy plugins, etc. But worth playing with

Was about to say "perfect, everything is there" but just checked and realized it's only 26 of 27 supported... "Disolve" blend mode is missing. Oops, will add

Two months ago I started working on Patchy, an MIT licensed cross platform photo editor. In addition to "properly feeling like Photoshop" it is the only open source editor that can handle 25+ years of my .psd files (including re-saving) accurately. Canceling my PS sub

Patchy 0.82 released! Tons of fixes and improvements, including being able to import Affinity (.af) now. Also, here is breakout being played directly inside of a layered image, an included test for its scripting system. Win/Mac/Linux downloads & source: github.com/SethRobinson...

Seth A. Robinson @rtsoft.com · 08/07/2026
Patchy 0.15 released - it's now multiplatform! (Windows, Mac and Linux) Any brave testers out there? Much faster and has a ton of new features: github.com/SethRobinson...

Seth A. Robinson @rtsoft.com · 04/07/2026
yeah, lot of limitations but even just 'digital loaning' (with lots of limitations.. 3 max at once, etc) is more than Steam and Sony currently offer

Seth A. Robinson @rtsoft.com · 04/07/2026
When physical dies, how am I supposed to (legally) lend/sell/preserve my games?! Any ideas on a system that publishers/stores might actually go for that work for digital? I'm thinking something like this would be a big step up from where (most) digital is now:

UGTBrowser 2.2 released on the chrome web store today: chromewebstore.google.com/detail/ugtbr... This is an open source browser extension for translation/language study I wrote for myself, but figured it might be useful for others (warning: requires an OpenAI API key)

Patchy is open source, something paint.net hasn’t been since 2009

Good software devs release when "it's done". Me? I release when "I'm done" as in, can't stomach working on it any longer

Released V2.37 of Toolfish with yet another audio feature - it can adjust the volume of just the app in focus. (hotkey to adjust Windows mixing) Makes it easier to watch youtube during the boring parts of games. github.com/SethRobinson...

a ton of openclaw instances and AI driven startups died this morning. No more free tokens I guess, only surprised anthropic allowed it this long

Tech tip (?): The dog-walking lights I ordered from AliExpress came the wrong color (I ordered blue) and too bright. Check out this easy hack to sort of fix 'em that even a dumbass like me can do:

Got a new printer - it prints on anything, even curved potato chips! So far I've been using it as a $2100 labeler, its camera positioning system makes it dang easy (and addictive) to use. Hrm, what else can I print on... (Credit: some pics are from @Yumcans's game Popslinger)

I think it ends tonight but here are my tips anyway: Show up at 5:30 PM and dress warmly. Stand away from the iPad in the center of your lane, use the Hold button from memory, you won't see next pieces. Play on "Hard", it's easy. We didn't try t-spin so not sure if it works.

Photo from last night at Kyoto station. They are letting people play Tetris on the massive stairs, using 15,000 LEDs. Met some friendly players, a pro with the coolest Tetris jacket scored 48K+, she ruled. ( 京都 大階段 )

Despite the lack of legs, my @pollenrobotics reachy robot danced off a table and damaged three motors. Finally sourced replacement motors (was hard in Japan, sold out), so hopefully we'll get this sassy little guy back online. Don't place it near the edge of a table!

I like tricky problems like this! for example, it has to manipulate the screen with taps like a human would do to clearly see cards/status effects. I think I'm too lazy (as usual) to do anymore work on it right now, but wanted to at least share the screenshot

Early work on an AI that can play Pokémon TCG Pocket only by watching the screen. Got to the point where it can reliably 'see' the cards and match them up to its internal card db to generate a super-prompt that produces structured movement advice

It also scans certain reddit subs and grabs top stories & comments. I allow it to create an image if there isn't one - with the requirement that it clearly labels it as AI generated, as it's hard to tell. Maybe a bad idea though, this image looks pretty real, for example...

Couple of reasons why I find this useful: 1. Has a section where it checks raw Japanese news and includes political bias tags for the source. 2. Kyoto event section includes distance from my house, pricing and one click google map.

Been experimenting with OpenClaw (w/Opus) to send me daily Japan news digests. It doesn't get blocked grabbing news and photos because it just switches to a real browser (on its VM) when needed. Today's version: rtsoft.com/temp/daily_d...

At a party and too many people are talking, causing Reachy to get stunlocked? After speaking, cover up the mic array on top with a towel or something so it will stop listening and answer. (thanks Yael!)

Audio gain hack that works in the conversation app: AUDIO_GAIN = 2.5 # 250% volume audio_frame = np.clip(audio_frame * AUDIO_GAIN, -1.0, 1.0) robot.media.push_audio_sample(audio_frame) #put in front of this line

The Reachy-mini is a lot of fun. It really is like having a useless Starwars droid. Some tips: Can't set it up? At least one feb batch (including mine) got botched and needs to be reflashed. Speaker too weak? Can hack apps with a gain, helped a ton.

Seth A. Robinson @rtsoft.com · 13/02/2026
Yeah, it’s hard to know! I think at some point AI will likely start catching scams that most people miss, like detecting a fake Lababu or repro NES cart by comparing images, but early adoption can be risky.
