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

Some tiny #megaduck console icons drawn and rom patched into the title screen.

Taking a short break from main project for a quick afternoon #MegaDuck port of someone else's new (open source) homebrew Game Boy game. Only minor changes required to get it running. Hope to be able to release it soon. Surprisingly playable on laptop model considering blurry low contrast screen.

Poll results are in! Mostly the same as 2024. (Whats MAIN way people play #GameBoy / Color games) Combined results from Mastodon, Bluesky, and barely any Twitter this year. Very un-scientific and un-rigorous! 😅 #gbdev #gameboycolor #retrogaming #gbdk #gbstudio #rgbds

Been few years, return of GB Screen poll! What's MAIN way you play #GameBoy /Color games? Curious since supporting OEM screen takes effort for devs. No bsky poll, choose a number! 1. GB +Unmodded OEM Screen 2. GB +IPS mod screen 3. Handheld Emulator/FPGA 4. Desktop/Phone Emulator 5. SGB/GBPlayer

New minor release of tilepalquant: v1.0.1 It adds some standard presets for various consoles ( #GameBoyColor, #GameGear, etc). (a c++ port of rilden's tile based color palette reducer for game consoles) github.com/bbbbbr/tilep...

Ported rilden's (web) image palette reducer to a command line app, easier to use in project build toolchains. Great for making images fit game console Tiles x N Palette x N Color limits github.com/bbbbbr/tilep... Original here: rilden.github.io/tiledpalette... #retrogaming #gameboy #nes #megadrive

I (finally) posted a video of highlights fom the 2025 #gameboy game jam! Check it out to learn about some of the notable entries. 😊 youtu.be/JI5649nTCJQ

Cool to see another project making use of the SFC/SNES mouse on the Suepr Game Boy! Hope to see some GBBasic projects that use it. Also credit to vinheim3 for the original SGB mouse patches and concept.

Fun video by @catgraffam.bsky.social about drawing with QR-Paint, go check it out! Plus a new release which adds the Undo/Redo hotkeys mentioned in the video. bbbbbr.itch.io/game-boy-qr-... #gameboy #pixelart #retrogaming

If there's one thing the world needs - it's RGB modding a Tiger game•com.

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

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

CrossZGB v2026.1 is out! A C & ASM Game Engine for #GameBoy #GameBoyColor #SMS #GameGear #MegaDuck - New quality of life features and improvements for sprite management - New examples for sub-pixel movement and Z-order control - Fixes for music drivers github.com/gbdk-2020/Cr...

New version of QR-Paint with some fun features: - Draw with #SNES Mouse when plugged into a Super #GameBoy (building on demo by vinheim3) - Windows XP desktop themed SGB Border - #MegaDuck build with Printer support #retrogaming #pixelart #qrpaint bbbbbr.itch.io/game-boy-qr-...

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

Thanks for the kind words, drawings and suggestions about #QRPaint! New version updates -Game Boy Printer support -Hold B for fast cursor -Analogue Pocket build GB Printer had light testing, let me know about issues bbbbbr.itch.io/game-boy-qr-... #GBDK #RetroGaming #PixelArt #GameBoyColor #GameBoy

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

By jove it works...

Draw on the Game Boy and share direct to your phone with a #QRCode! No extra hardware and without the internet. QR-Paint is a small paint program for the #GameBoy with a fun way to export drawings. bbbbbr.itch.io/game-boy-qr-... #GBDK #RetroGaming #PixelArt #GameBoyColor

Full 2025 #GameBoy homebrew / indie Cart Release charts. Holding steady but 2022 was still peak. Big publishers down a bit, self-published up. Now with interactive web charts (links in reply) Data from @dmgpage.bsky.social : dmgpage.com/homebrew-rel... #gbdev #retrogaming #indiedev #retrodev

Did the yearly update to my web list of #GameBoy flash cart vendors & options. A couple carts went in/out of stock. Prices didn't change much (unclear if tariffs apply) New vendor is "GB Make" but they lack specifics such as MBC type, SRAM size, etc. bbbbbr.github.io/GameBoy-Flas...

The Year Wrapped for #GBDK & #ZGB! 2025, another good year for releases! Here's a browse of #GameBoy, #NES & #SMS/#GameGear games people made with #GBDK2020. Check out the gallery & give some a try, most free to download & play. gbdk-2020.github.io/gbdk-2020-ga... #indiedev #retrogaming #retrodev

Finished Infinity- had a great time. Gameplay and difficulty were reasonably balanced (bit easier than expected), UI worked well, overall polished and well done. Long time since playing an rpg, was a decent return to the genre. Congrats to the team on finishing development. #infinitygbc #gameboy

Carrot successfully delivered to goat. Would be ok with this as an alternate end to the game. 😅 #infinitygbc #gameboy #gameboycolor

Woo! I've updated my #MegaDuck ROM patch on itch for Fydo's Magic Tiles to note that the source ROM is now **pay what you want**. 🎉 Recommend checking out this charming puzzle game for the Game Boy *and* Mega Duck. :) bbbbbr.itch.io/megaduck-pat...

#MegaDuck Super Junior Computer gets reversed! I invested several hours to pull "proper" schematics out of the PCBs and shared them on GitHub. During the process I also completely redrew the MainBaord PCB surrounding the CPU.

An obscure cpu clone of a #GameBoy won't support a system RTC date past 2011. Found this Y2K12 bug while disassembling the system ROM of the #MegaDuck laptop model. The hardware itself could do it, but I guess they didn't think anyone would still use the console 15 years later (made in ~1995)

The final leaderboard of the 'Game' category of #gbcompo25 was just published. Congratulations to OrmBlok, Fortune & Glory, Potion Panic, DropBlox! and Game of Life Kuzushi for winning the 'Best Games' awards! gbdev.io/gbcompo25.ht...

Late breakfast out and about. #gameboycamera #gameboy #photography

Dedication to the cause

Finally! External #MegaDuck Laptop HDMI based on #PicoDVI is working. This is pulled directly from @remysharp.com pico-dmg-arcade as I'm currently unable to compile working code myself. Need to figure out how, to add audio support though 😁

Lets get some Game Boy homebrew included on there

I've updated my Mega Duck ROM patch on itch for Nocptern to note that the source ROM is now **pay what you want**. 🎉 Cool #shmup for the Game Boy. Hope this means some more people enjoy the game on the #MegaDuck too :) bbbbbr.itch.io/megaduck-pat...

Andddd..... Here it is. Den Of Snakes Four Player, a family of public domain pixel fonts. Free download at: bbbbbr.itch.io/den-of-snake... #font #gameboy #pixelart #pixelfont

Den of GBBoys Checking compatibility. #GBBoy Seal of Approval earned. Even though their clocks run fast the game stays in sync due to how it uses the 4 Player adapter. Q: Is that older GBBoy Colour with a very scratched screen actually a color console? A: No! They just changed light grey to red!

Den of Snakes, a new homebrew game for the Four Player #GameBoy adapter. - Have a 4 Player adapter and play it? would love to see pix - Find bugs or problems? let me know Rom on Itch: bbbbbr.itch.io/den-of-snake... Open source: github.com/bbbbbr/gbdk-... #retrogaming #gbdev #nintendo #pixelart

My IPS mod for the #MegaDuck Super Junior Computer finally got a frame to hold the GBP Q5 display. It also locks against the adapter PCB and creates a good tight fit ^^ Now I need to find a nice way to access the OSD without the capacitive-pads (inconvenient)

Wait's over. We're about to reveal, entry by entry (and in no particular order), the final #gbcompo25 shortlist! Those 19 games will be the ones competing for prizes and they will be ranked in the final leaderboard. Stick around till the end of the thread… we have a special surprise for everyone!

Me: Trying to finish a (rather delayed) very basic game showing how to use the Game Boy 4-player adapter My brain: How about you make a new 8x8 pixel font just for this trivial game instead of finishing your code ... #font #gameboy #pixelart

I'm only an organizer for gb compo and not a judge, but I still try to play all the games. GB Compo entrants - I have now played through all ~119 of your games! Thank you for participating and making so many cool and delightful games / tools / music! Had a lot of fun! #gbcompo25 #gbcompo
