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).

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. 😄

Screenshot of qrpaint in a game boy emulator, the whole screen is dimmed except a small area around the fill-style selector with three types, hollow, foreground-fill, background-fill

Small update to #QRPaint (v0.9.3) that adds selectable fill style for the Circle and Rectangle tools.

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

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)

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. :)

#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.

Mega Duck版 IMPETUS+ micro #megaduck

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)

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 😁

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 :)

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)

The #IPS kits and #PCB adapters for #MegaDuck arrived! Time to get #hacking!

We just got a #MegaDuck printer! It's in very good condition and working just fine 👌

Therefore we can now properly trace the printer protocol, reverse it and make printing accessible for everyone 😁

Even though we then still need to figure out how to enter the 4-color mode 🤔

If you're wondering what the #MegaDuck laptop hardware looks like, you can watch this fine video by @ashens.bsky.social to see the console in all it's glory.
