I've been wanting to modify the original Nintendo Gameboy so I decided to restore and repair one and do the modifications while I'm at it.
The original Gameboy aka DMG-01 was released in North America 31th July 1989, few days shy of 31 years!
HTe modification I will add to this console is a backlight and a bivert chip.
Bivert chip inverts the colors.
For some reason that gives better contrast for the screen, I'll also invert the colors again to get normal colors instead of inverted colors.
