I initially planned on recoloring nexus6's RetroGUI theme but then it got a bit out of hand. I'm pretty much just keeping his vectored consoles.
I started with Colecovision for some reason. I am planning to do the whole emulator set and a vertical MAME.
I'll upload the .svg files (Inkscape) when I'm done to the appropriate place. Hope you like it!
[edit: Just made a revision to include a Centipede-like font. I'm not sure if I prefer it or not]
