A compact simple supergun based on the minigun design by Frank_fjs.

This version replaces the 8 pin Mini DIN output of the minigun design with a Genesis 2 compatible 9 pin Mini DIN output. It also replaces the 6 pin Minifit Jr. power plug with a 20 pin ATX power connector and a 6 pin JST B6P-VH connector so you can use an ATX or a real arcade power supply.

These changes were made to accommodate my personal setup, not necessarily to “improve” the original design. I hope you enjoy it!

This is a multi console controller to DB-15 adapter board that I designed to work with my Saturn Pad Demux , SNES to DB15 Adapter and my PSX to DB15 Adapter firmware.

DB15 pinout is compatible with Undamned’s DB15 Pinout. RJ45 cable pads are labeled according to the MC Cthulhu naming convention and wiring guides.

J1: J1 should be closed during programming and updating the board via SPI. It connects RESET from the ATMEGA328P to pin 9 of the DB15 connector. I’m not sure what most Superguns do with pin 9 since it’s not used on any pinouts that I could find. As such J1 should probably only be closed while programming, just in case your Supergun does something silly with pin 9.

SW1: SW1 is connected to pin 3 of the DB15 connector and is used to add credits. If you are using this board in Saturn mode you will need to have SW1 on the board since the Saturn controller doesn’t have a select button. If you are using Playstation or SNES mode, Select on the controller acts as the Coin button so SW1 is optional.

BOM

U1: Atmega328p TQFP32

C1,C2: 0.1uf 0603

R1,R2: 100ohm 0603

R3,R4: 1kohm 0603 or short. (R3 and R4 are meant only for Saturn mode, although you can get away with just shorting them if you don’t want to add the extra resistors.)

This is a modified version of Borti4938’s N64RGBv1 board with integrated 3.3v regulator for clean noise free RGB video output. Note that this version of the board does not support MAX V CPLDs, only MAX II.
