I wanted to draw a board of my own even though Raphaël has everything needed to etch a board. My design was supposed to have both PLCC and DIP sockets on the same board but I didn’t manage to fit them within a reasonable sized PCB. :/
As some demoparties (like Breakpoint) require you to demonstrate that your compo entry runs on real hardware, having this cart would’ve allowed me to enter music made on/for Megadrive to such parties.

Board is not tested, so if you decide to try this please let me know how it turned out!
