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.😄
