To anyone who was designing a cart PCB for Sega Genesis/MD

Hi once again!! I want to design a custom cartridge PCB for Sega Genesis/Mega Drive 16bit and here's my question- has anyone designed one?? If yes, wouldn't you mind providing me your PCB template?? I mean I only need the entire info about the PCB, for example what size it should be, thickness etc. That would be also great if you provided me a template PCB as I mentioned before. This can be only an empty PCB with the most basic stuff like PCB size, connector etc. I know how to fill it with traces, solder pads etc. I guess you get the idea . Any kind of help will be strongly appreciated!! Big thanks in advance!!
