Want to go retro on your browser? From whom I'm guess is the same person who emulated The Legend of Zelda: Link's Awakening on HTML5 comes a full fledged GameBoy Color emulator that runs on HTML5. With games such as Super Mario Land, Mega Man Xtreme, and the 3 major Zelda games on the GameBoy, this cool little blast from the past is sure to be a... well, blast.
Button Map: X or J = A Z or Q = B Shift = Select Enter = Start D-Pad = JoyPad ESC = Fullscreen r = Raise Volume d = Lower Volume
In case you missed the link the first time, you can play the GameBoy Color emulator here.
Thanks to @twittkins yet again for the tip.
