       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.😄(device photo credit ashens on youtube iirc)#gbdev #y2k

       Also the min year is 1992, presumably the earliest rounded-down leap year to when development started, due to some look up tables it uses for handling Day of Week calculation and so on.The power-on reset for the year is 1994.
