Build your own Sega VDP cartridge

Franky DIY PCBThanks to Brazilian MSX developers FRS and MSXPró, we can now publish a do it yourself guide for building your Sega own Audio and Video cartridge named “Franky”.


FRS took over some bare-boned pcb’s and worked out a instruction manual together with MSXPró. MSXpró improved the original design with better audio, audio and CVBS connectors and support for real vga monitors (that can handle 15KHz signals).

Because the cartridge enclosure needed for the board is hard to come by, we developed a 3D model of the  cartridge enclosure needed together with Dutch 3D- model company D-byte, which we offer as a free download to use in your own personal projects. This model is compatible with Philips NMS 1250 and Sunrise Moonsound type casings. The model is in the Sketchup format (plug-ins exist to export to .stl and other formats your 3D printer accepts)

Price for one Franky PCB board is 15 euro. That includes worldwide shipping (unregistered by letter mail). Please note that this only contains the pcb. You will have to acquire the necessary parts yourself (the part list is in the manual).

Thank you for your support and happy holidays!

P.S. The order page and form is now updated, you can order one or multiple pcb’s. Please note that multiple pcb’s will be only send registered, so you need to order 6 pcb’s or more to make it cheaper for worldwide shipping.
