Overview
Pif fpga is an open-source printed circuit board by jago85, from the jago85/UltraPIF_Hardware repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 35 × 41 mm with 61 parts on 67 nets, routed with 1,043 tracks and 169 vias.
It is built around the STM32F070CBT6, W25Q128JVPIQ and 74LVC1G14Z, with the SI5351A-B-GT among its other parts. Its parts include 27 capacitors, 10 resistors, 5 ICs, 4 connectors and 1 inductor. It belongs with the fPGA and programmable logic boards and the STM32 and FPGA and CPLD boards of this library.

README
README.mdUltraPIF_Hardware
The UltraPIF is a replacement for the N64 PIF-NUS chip.
The PIF-NUS chip responsible for region lockout and copy protection. But it also has essential features like game controller access, cartridge EEPROM access and it includes the MIPS CPU boot rom.
The UltraPIF can replace all functions of the original PIF, but ignores the CIC and thus enables a region-free N64. In addition the UltraPIF comes with an integrated clock generator to compensate the differences of the video clocks for NTSC and PAL consoles. The UltraPIF includes an SPI NOR FLASH used to store the N64 software images. At the moment the FLASH is 16 MiB in size and 99% empty, so there could be features like backup and restore of savegame data or even direct emulation of SI (serial interface) hardware (ControllerPak, cart EEPROM, RTC). An RGB LED replaces the original N64 power LED and is used to show if the N64 is running in NTSC or PAL mode. The color is user programmable.
The project consists of custom PCBs, an FPGA design, an MCU firmware and a bunch of software for the N64 itself.
In this repository you find the KiCad hardware files.
You can find hints for assembly and installation in the wiki.

Questions
How big is the Pif fpga PCB?
It measures 35 × 41 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pif fpga use?
61 parts, built around the STM32F070CBT6, W25Q128JVPIQ, 74LVC1G14Z and SI5351A-B-GT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pif fpga KiCad files?
From the jago85/UltraPIF_Hardware repository on GitHub, at the commit this page was made from: the board is pif_fpga/pif_fpga.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pif fpga design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
