aten_panzana released a patch for #gameboy #Pokemon Red/Blue to run on the #MegaDuck. (based on the pret disasm)
To run it on hardware requires MD2+MBC5 SRAM cart (or a cart slot adapter). There's demo picoDuck firmware for that, and some upcoming flash carts. It can also be run in the SuperJunior SameDuck emu (use ".md25s" file extension.)
Patch at:
https://aten-panzana.itch.io/mega-duck-patch-for-pokemon-redblue-game-boy -
Thanks to:
- Liam Robertson's research and documentary
- LIJI whose Same Boy emulator I based my MegaDuck research fork on, and Workboy reference code
- The #MegaDuck community for motivation to finally finish this beast! -
The legendary #Workboy found a new home!
I ported the ROM to work on the #MegaDuck laptop (a #GameBoy clone). It's not the hardware that we wanted, but...it's hardware that exists! Keyboard, Real Time Clock and all.

New release of #SuperJuniorSameDuck (my fork of SameBoy with #MegaDuck laptop support)
- Support ".md2s" file extension (MD2 mapper + SRAM)
- Preserve VRAM on "Load Cart From Slot" command, allows ROMs to detect whether they are running on Spanish vs German laptop model
- A couple other debugger related improvementshttps://github.com/bbbbbr/SuperJuniorSameDuck/releases/tag/Duck_v1.0.2

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

Found a new command for the #MegaDuck laptop Peripheral Controller today.
0x14 Switches the link port away from the Peripheral Controller to the external (DB15) port.
So far not sure if it's possible to switch it back. Which means if used you lose access to the keyboard, rtc, printer and other commands until hard system power-off.

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. 😄
https://bbbbbr.itch.io/game-boy-qr-paint -
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 -
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)

Now you can print your GB-Wordyl results on Mega Duck Laptops!
The new release adds #MegaDuck thermal printer support, likely the first homebrew to use the printer hardware.
https://bbbbbr.itch.io/gb-wordyl/devlog/1007495/gb-wordyl-v107-mega-duck-printerPrinting also works in the #SuperJuniorSameDuck emulator for the Mega Duck Laptops

Update from last night- Printer timing and output getting better.

Almost have the #MegaDuck Printer working.
Reverse engineering the protocol apparently being easier than getting the hardware timing right. Not sure how much buffering there is. And not able to easily snoop the signals to get a reference.
The dithering is intentional since this is the 1-pass mono color model, so the 4 shades of grey have to be reduced when printing.

#GameBoy 4-Player adapter mysteries solved & working great.
Now we have snakes, 4 of them! And synchronized game play across 4 consoles. Game mechanics still work in progress.
Adapter interface code now open sourced & documented:
https://github.com/bbbbbr/gbdk-gb-4-player/blob/snake_game_tile_locked/src/4_player_adapter.c -
Welllll it was a bit of a struggle (some ambiguity in docs and hardware sensitive to out of spec input)... but making progress.
Can send and receive data from the #GameBoy 4-Player adapter reliably to move some blobs around in parallel. A couple mysteries remain to investigate.

First release of #SuperJuniorSameDuck, my fork of SameBoy with support for #MegaDuck Laptop hardware (only current emulator for it).
Features: supports Keyboard, RTC, Printer, Cart Slot and MD0 mbc.
Runs Spanish and German System ROMs, Bilder Lexikon and DataBank.
Coding: Upcoming GBDK release will have C source examples for laptop hardware.
https://github.com/bbbbbr/SuperJuniorSameDuck/releases/tag/Duck_v1.0.0
Homebrew: My wordle port is only known homebrew for the Duck Laptop (hope to see more!)

Emulation for both #MegaDuck printer types now ~working. With that it's much easier to write printer code on the game side.
So I added printer support into GB-Wordyl for the Mega Duck. You can press printscreen most anywhere in the game.
Still no actual printer hardware to test, so prob wait on new release.
The emulation is sufficient enough that the OEM ROMs which use it all seem to print ok. Some fine timing on the hardware replies is likely off.

More Printer hardware emulation progress for #MegaDuck laptop. Decent output now (greyscale pix).
Seems there are two kinds of printers. Single pass monochrome and two pass that attempts grayscale.
The special game/util carts for laptop apparently support the printer (Bilder Lexikon, Data Bank).
(For now SuperJuniorSameDuck is the only emulator that can run these ROMs. It's my fork of SameBoy with extensive MegaDuck support)
