You may have heard of the Game Boy Zero, but instead of building a standard game boy zero, try to fit as many features as you can, into the original DMG gameboy shell!
Essentially it uses a Pi Zero, powerboost 1000c, TFT composite lcd, etc. What can you turn this project into? Perhaps a Game boy Zero with 5 more buttons? How about a a screen dimmer, brightness control, ability to sync 2 together? Whatever the case, can you accept my challenge and build a Game Boy Zero that has more features then what 90% of the community does with them?
Do some research on the GBZ, and check out a few YT videos! Let's see Ben Heck build the greatest GBZ ever to be created!
