Made a replacement Gamepad ("Mouse") for a #MegaDuck Super Quique laptop using a gutted aftermarket SNES pad.

Added the wiring diagram and other details on how to make one to the MegaDuck info page.

The multiplexing seems similar to what I understand the #GameBoy DMG/MGB use. (Not a surprise since it's a clone)

Did an very basic clock speed test between a couple oem Game Boy devices and clones.

AP and Duck come out well, at least over a 17 minute time period.

FPGBC is still a bit fast with the latest board and FW rev (1.06)

Stock GBBCs a little slow, but less off than FPGBC.

GBBoy SNES Converter & #GBBoy : 63300 -> -0.66%

#FPGBC: 64260 -> +0.84%

#AnaloguePocket: 63720
#MegaDuck: 63720
#GameBoy Pocket MGB:63720
#GameBoyColor GBC: 63720

GB-Wordyl for the #MegaDuck Laptop models!

Possibly the first homebrew release to ever use the physical keyboard on this console. The MegaDuck is a slightly altered Game Boy clone, and there is even this weird and delightful laptop version.

With some reverse engineering it's now possible to use some of it's special features.

ROM:

Thanks to Eucal.BB for help with laptop model testing!

Open source, of course :)

Been reverse engineering (keyboard, rtc, etc) the #MegaDuck #SuperQuiQue laptop.

It's like #GameBoy #Workboy except it actually shipped. It has same GB compatible cpu (sm83) and with slightly altered registers as the Megaduck Handheld.

Anyhow, turns out the System ROM has a Y2K12 bug. The, max year supported is 2011.😄

How-to article (not by me) about a screen mod for the #MegaDuck console using aftermarket #GameBoy DMG IPS screens and a small flex cable adapter.

The #romhack patch for #GameBoy #tetris to run on the #MegaDuck is done and available. 🦆 🦆🦆

It can run from the Inside Gadgets 32K megaduck carts. If run in an emulator some music or sfx may sound off a bit.

Patching #GameBoy #tetris to run on the #megaduck. 🦆

Already playable and in decent shape. Some (hopefully) small audio driver things to fix, check over and clean up.
