This project is something I've slowly been chipping away at, for a little while now. It initially started off as a small exercise in procedurally 'modelling', a standard Game Boy Cartridge in Substance Designer. Having achieved that with some degree of success I thought, "Hmm... I wonder...". Aside from the 'Cartridge Art Atlas', I assembled in Photoshop, everything else is fully procedural.
I've got to give a massive thanks to Daniel Thiger, and his Fundamentals Series. I was able to pick up quite a few new tricks and techniques, which really helped out.
