Famicom/NES Copier PCB Dumper/Writer

Project Description: Famicom/NES Dumper/Writer (ClusterM/famicom-dumper-writer)

This is an advanced, open-source hardware device for dumping (reading) and programming (writing) cartridges for the Famicom (Japanese version of the NES) and Famicom Disk System (FDS) cards. Created by ClusterM (Alexey Cluster), the project aims to create the perfect Famicom/NES data bus simulator, featuring highly accurate M2 clock cycle emulation and the use of the FSMC (Flexible Static Memory Controller) for accessing PRG (program) and CHR (graphics) memory. Thanks to the CPLD chip, it achieves high speed and precision.

Key Features:

• Dumping cartridges to ROM files (for use in emulators).
• Support for reset-based cartridges (simulation of pressing reset).
• Support for cartridges requiring continuous M2 clock.
• Reading/writing battery-backed saves (transferring game progress between emulator and console).
• Programming multicarts: COOLGIRL (ClusterM's own project), COOLBOY (mapper 268, chip AA6023 – may require soldering), UNROM-512 (mapper 30, e.g., RetroUSB).
• Reading/writing FDS cards using an FDS drive with a RAM adapter.
• Cartridge testing and reverse engineering (NES bus simulation).
