(Mild language warning)
Well, this is most interesting. An unlicensed Chinese NES Tamagotchi ripoff, it seems, based on this video.
I thought I could bring this to the community's attention for... entertainment purposes, I guess. If anyone else has an NES emulator and can find a ROM this might be interesting to explore.
It's even better because I know absolutely nothing of the Chinese language!
EDIT: I've acquired myself a copy of this game and am now raising my first Flighty Chicken, who I have (now rather ironically) named 'Happy'. I can't seem to keep it happy! D:< Also, hatching the egg takes forever and you have to keep its temperature even (like a Mori No?). It seems that the first meter on the meters option (looks kinda like a fortune cookie) would be 'hungry', the second 'happy', and the third and fourth... remain a mystery to me.
