It's a cool technique! It also showed up in those Game of Tobi 3d voxelish demos.

The legendary #Workboy found a new home! I ported the ROM to work on the #MegaDuck laptop (a #GameBoy clone). Not the hardware we wanted, but...it's hardware that exists! Keyboard, Real Time Clock and all. Free #DuckDuckWorkboy #rompatch on the itch page: bbbbbr.itch.io/mega-duck-pa... #romhacking

Found a hidden treasure in #GameBoy #Workboy ROM (looking for Bank 0 free space) Menu shown when run without keyboard connected has hidden "Backup Options" entry. To reveal search for "ITCMRT" in phone app (cart sram must be init-ed). Appears to Dump/Restore cart SRAM to keyboard over link port.

New release: little #GameBoy and #MegaDuck on-console memory hex viewer / editor. Made it for inspecting save data on the Duck Laptop where the SRAM can be on a separate cart than the ROM. Possibly of use for casual Game Boy memory peeking and poking too. github.com/bbbbbr/gameb...

Screenshot of hex editor running in a game boy emulator. There is a gred of hex numbers in the middle with hex address information on the left side. The bottom says "Wr Value, Write @:FF47 <- F9". Running in dark mode.

Made a source-patch #MegaDuck port of the recent #Celeste Classic #GameBoy version by Rous/joshop. Playable and fun even on blurry oem screens. bbbbbr.itch.io/megaduck-cel... Patch and binary made and shared with permission, only needed minor edits to get it running on the good duck. #retrogaming

Could be fairly efficient. Not sure how @coffeepowerup.bsky.social implemented, but my reproduction of theirs only has 2 calls (when x/8 or y/8 changes) - One fill_bkg_rect() to clean up trailing edge - One set_bkg_tiles() to copy a fixed pre-made attrib map with the torch shape made of palettes

Did an IPS screen mod for the Supaboy handheld #SNES clone. Viewing angles are soooo much better. I'm really bad at getting flex cables into their connectors, but eventually prevailed.

OK, apparently couldn't resist one more feature in #QRPaint (v0.9.4). Added a Spray tool with a slightly over-engineered random spray and flow rate. 😄 bbbbbr.itch.io/game-boy-qr-... #Gameboy #Megaduck #pixelart #retrogaming

Screenshot of qrpaint in a game boy emulator, there is a drawing of a mountain ridge in black with dithered white highlights on the left side of the peaks and a dithered sky going from top (dark) to bottom (light) and a black moon or sun.

Screenshot of qrpaint in a game boy emulator, there is a drawing showing different sizes and durations of the spray tool with lower and higher densities of random pixels (lighter and darker overall effect).

Small update to #QRPaint (v0.9.3) that adds selectable fill style for the Circle and Rectangle tools. bbbbbr.itch.io/game-boy-qr-... #Gameboy #Megaduck #pixelart

Screenshot of qrpaint in a game boy emulator, there is a drawing of a smiley face and lots of overlapping circles and lines

The output size of the #GameBoy printer is cute, but the larger print format of the #MegaDuck (a Game Boy clone) printer is much better for pinning up or the fridge door. (coming soon to #QRPaint: a Mega Duck port) GB on left, Duck on right #retrogaming

Side by side comparisons of the Game Boy Printer and Mega Duck printer with images. Both showing prints of a dogcow and flower. The game boy prints are about 1 inch tall and the Mega Duck ones are about 2 inches tall

Looks like they are aiming for a freemium model.

For now, Tangled is not monetising. Instead, its focus is on building the best next-gen code forge.

“Down the line, we’re inspired by companies like Tailscale: give the product away to individuals and open-source users, and charge businesses for enterprise-level features.

Eighty per cent of users get it free. The twenty per cent who need advanced capabilities — companies — pay.

That approach creates goodwill and love for the product. We’re still designing what that looks like for Tangled, but we won’t paywall core functionality.”

What if you could misuse a @furrtek.bsky.social GB-303 music cart as an etch-a-sketch in QR-Paint? Just trying it out, so far not planning to make it a formal part of #QRPaint since it would result in some feature limitations. #GameBoy #EtchASketch

Thanks! Your self published version is present. If the incube8 version is digital only then it won't be included since these charts focus on physical cart releases.

Might be cool to see that screen with the color bars. bbbbbr.itch.io/gbc-colorbars Recently compared oem vs non-backlit GBBoy colour which seems to have 3-bit rgb output instead of 5-bit (the range clamping could be due to ORing the top 2 bits together, and same for bottom 2 bits).
