Game Boy Zero config menu

This is a simple config menu to be used at Game Boy Zero projects

It's a Work In Progress (still only at visual part =p)

Requirements

• SDL2-dev
• go-sdl2
• go yaml package

At debian based linux you can install them with:

apt-get install -y libsdl2{,-mixer,-image,-ttf,-gfx}-dev
go get github.com/veandco/go-sdl2/sdl
go get github.com/veandco/go-sdl2/ttf
go get gopkg.in/yaml.v2

How to use

Just clone the repo at your gopath src and build it with go build menu.go and then use it with menu yamlmenudefinitionfile.yml

Please note that the EmulationStation input file is hardcoded as /opt/retropie/configs/all/emulationstation/es_input.cfg for now, you can change it at line 41
