Had a rather stupid idea today, so I immediately stopped what I was doing to go through with it.
An edited version of the title screen from the SNES game "Goof Troop", where the only difference is that it now reads "Oof Troop".

The image shows a background colored entirely in green. In the center is pixel art of Goofy and Max, covered by the "oof" in big yellow letters and "troop" in smaller red letters below. To the top left of the title logo is the "Disney's" logo. There's menu options on the bottom reading "Password", "Game" and "Options", with the "Game" option currently highlighted in yellow and the non-active options in brown.

New arrivals, and @radicalfishgames.com are cooking once again with their merch! Excuse the slightly crappy photos, but both shirts feel very high quality. I love how cleverly the graphical design extends to the back of the shirts! XL size also feels perfect for me and is incredibly comfy.

The black shirt on the left features the official CrossCode logo design, the blue shirt on the right features a silhouette of Lea in front of a red sun, with a blue CrossCode logo below.Back sides of the two official CrossCode shirts from Makeship. The black shirt on the left features some abstract circuitry, whereas the blue shirt on the right features some blue and red strokes, roughly aligned in a circular fashion around the outside of the shirt.

Not me having such a weird week at work I develop a second personality.
A photo of "hide the pain"-Harold, looking at the viewer with a facial expression that looks like a painful smile, giving a thumbs up. He's sitting inside a chair at a desk. On the desk, there's a laptop, a cup, glasses and some other unidentifyable devices. In the background, there's a blurry clock, a window and a lampshade.

Windows, PLEASE! I was only trying to install MSXML, NOT to summon The Ancient One!

I took out my old GBA that has only been sitting in my drawer for (probably) 10-ish years, and it has yellowed so funnily that it looks orange now. You could almost mistake it for an official clear orange shell without seeing its backside.

There's a big scratch on the display.Photo of the backside of a Game Boy Advance sitting on a green blanket. The shell is clear white but appears clear orange at the rims. The buttons are gray.

I've been pretty quiet about this recently, but have actually been working on it pretty intensely! Now there's only a few important features missing before I'd consider that a viable v1.0. To the left is the logo I've created (not perfect, but kinda fun), to the right the current archive WIP.
A window-shaped icon with a cyan title bar and border and a dark cyan background. The title bar contains a red circle with a white dot inside, representing a UI badge. Next to it a long white line, representing a line of text. Inside the window there is four roughly rectangular shapes representing tabs, but they're bent and overlaid on top of one another to form the letters "P" and "T".A screenshot of a work-in-progress tab archival extension. The title reads "Archive". Below it is a text field labeled "Filter:" with the word "YouTube" filled in. Below it are three groups in cyan titled "Categories", "Sessions" and "Unsorted Tabs". The groups have red badges next to their titles, indicating the number of tabs and sub groups with the respective group. The second group, titled "Sessions", is currently open. In it is a sub group in gray labeled "January 15, 2026 at 01:37:30 PM". This group, too, is currently open, and within it is a gray rectangle with a play button icon and the text "YouTube", representing an archived tab.

The entire @radicalfishgames.com is now unite! Who cares about not having any space for more plushies, anyways. 😌

I've actually shown it before on my profile, so no secret here! 🙂 It'll be an extension for automatically archiving and categorizing open tabs so that I can get my tab messiness under control (funny how this once again ties into cleaning! 😂). Screenshot is from current WIP version.
A screenshot of a website titled "archive". Below the tiltle, there's text search field labeled "filter...". Below that, two groups in cyan labeled "categories" and "sessions". The "sessions" group is unfolded and reveals multiple groups in gray nested within it with dates as titles. The first of those groups, titled "January 16, 2026 at 04:03:29 PM", is unfolded and contains a list with icons and names of various websites, such as YouTube or Amazon.

Oh, you thought I was joking? Thought I was making a funny, didn't you? Well, I was dead-serious. And I'm WAY too invested in this! Event spent literal hours trying to get a dark mode to work. On the plus side, I'm FINALLY learning some CSS and JavaScript basics!
A screenshot of some website UI.

The header on top reads "Tab Archive". Below that a label reading "Filter:", and below that a text field reading "Filter...". Below that there's a collapsed group in cyan reading "+ Categories [4]", and below that an expanded group in cyan reading "- Sessions [4]". The sessions group contains a nested gray group reading "- 21. November 2025 um 21:36:48 [4]". Inside this nested group there's a list of tabs containg a fav icon and a title. This group also has a button in its top right corner featuring an icon of a red trash can.

You just know your tab messie syndrome is out of control when you wake up one morning and think to yourself "Hey, let's create a Firefox plugin!"
Screenshot of a Firefox extension from Firefox's extensions view.
The title reads "Tab Archive". The description reads "Automatically archives open tabs into categories based on customizable patterns". The logo is the text "Tab" in black and the text "Archive" in red on a gray background.

Okay, yeah, shiny-hunting in Legends Z-A is definitely busted, lol! This was after roughly one hour of reloads with the shiny charm. In total six shinies had spawned. I love it!

Maybe it's time to finally boycott Google as a search engine and move to something else. I'm already not too crazy about everyone and their moms trying to shove AI content into my ass, but putting the new "AI Mode" button to where "All" used to be is just hostile as fuck.

Wenn die Autoübersetzung auf AliExpress einfach aufgibt.
Ein Kommentar auf AliExpress mit folgendem Inhalt:
"Der Emballage, aunque durch den Transport roto. Ein bisschen toque auf la chapa. Die Pantalla, die de la puerta hace, viene doblada. Der interruptor viene con un adaptador y la lampara es de USB pero no viene adaptador. Ich probaré la maquina estos días y veré como funciona todo. Generalmente bien, aunque der Preis könnte verbessert werden."

I just had the stupidest idea...
A parody of Super Mario 64's intro screen. Instead of Princess Peach, it shows Dr. Eggman from the Sonic series, and the letter is altered to read:
"Dear Sonic: Please come to the laboratory. I've baked a Chaos Emerald for you. Yours truly-- Dr. Robotnik, Eggman"

These Nendoroid look like they were made for one another!
On the left, a Nendoroid figure of Anya Forger from Spy X Family with a shocked expression on her face. On the right, a Nendoroid figure of Patrick Star from Spongebob Squarepants with two Krabby Patties in his arms and a happy expression. With the two figures side by side, it appears as though Anya was shocked by Patrick's burgers.

Jack Chick definitely was on to something here.
A panel from the chick tract "Dark Dungeons" with some sloppy MS Paint edits applied to it. On it, we see a girl with a grim smile on her face, overpainted to wear the outfit of classic Mega Man. Her edited dialog reads "I used the Mega Buster on my father. He was trying to stop me from playing Mega Man."

POV: You know damn well that what you're trying is probably just janky speedrun tech and not at all the intended solution, but you've almost made it work once and you're just too stubborn to give up now. (Potential minor exploration spoilers for @animalwell.bsky.social )

Oh right, I made these sprites once for MaGMML3. Might as well share them here, too! Some are edits to existing sprites, some were made from scratch. I don't even consider myself artistically skilled by any means, so I'm still somewhat proud of these!

Finally got this to at least look acceptable. Now I just gotta add the actual menu logic and then fill it with meaningful content.

Me trying to create a new thing once again and failing in hilarious fashion once again.
A screenshot of a work-in-progress implementation of a Test Suite for my VWF Dialogues patch. The screenshot shows a screen that generally looks somewhat intelligible, with the heading "Test Suite", but then the actual entries of the screen are just a glitchy mess. Individual tiles are either invisible or replaced by garbage.

A little code optimization porn. I haven't tested if the new routine is actually faster, but since it uses way simpler instructions, it ought to be. Just getting rid of the SA-1 distinction already makes it worth it to me, anyways.
A screenshot comparing some SNES ASM code before and after optimization. The "before" version uses multiplication registers, whereas the "after" version does not and uses a lot simpler instructions overall.
