Brutzelkarte - N64 Flash Cart PCB (KiCad)

IMPORTANT!

This project does not support piracy! You are only allowed to play games you own yourself and you have to create your own ROM images.

Features

• Open Source hardware and software
• no BGA packages (DIY friendly)
• no original chips from victim modules needed
• FPGA based logic
  • Lattice LCMXO2-7000HC-6TG144C
  • flexible (everything goes through the FPGA)
  • updatable (internal FLASH can be updated over UART)
  • expandable (free ressources for new features)
• 64 MiB (512 MBit) QSPI FLASH for ROMs
  • can be split into multiple parts for smaller ROMs
  • download is slow compared to SD card based carts
  • once a ROM is flashed the boot is as fast as the original module (no need to select and load the game every startup if you want to focus on a specific game)
  • can be expanded in the future (QSPI FLASH chips can use the same pinout for bigger memory because they don't need additional address lines)
• 8 MiB (64 MBit) dedicated for cart menu
• 256 KiB battery backed up SRAM for savegames
  • SRAM can be split into multiple savegames
  • emulates all cart based savegames
    • EEPROM 4 KBit
    • EEPROM 16 KBit
    • SRAM 256 KBit
    • SRAM 3x 256 KBit
    • FlashRam 1 MBit
• RTC
  • only used by Animal Forest
• integrated FT232RL USB-UART
  • direct UART TTL connections if you want to save the money for the FT232RL
