-This is a simple dumper/writer for Famicom cartridges and Famicom Disc System cards. This version is much faster compared to the [old one](https://github.com/ClusterM/famicom-dumper). It's using a very accurate M2 cycle simulation and FSMC (Flexible Static Memory Controller) to access PRG and CHR memory. FSMC is precisely synchronized with the M2 clock signal using a CPLD chip. The new version is also using a fast on-chip USB controller instead of a slow FT232 USB-UART converter.

+You need to write firmware to two chips: the STM32F103ZET microcontroller and the EPM3064 CPLD. But actually you need only to flash bootloader to STM32 using ST-Link programmer. Using bootloader you can flash both firmwares: to the STM32F103ZET and to the EPM3064.
+
+How to use bootloader:
+* Disconnect device from USB
+* Short the ground and the IRQ pins using tweezers or scissors
+
+* Connect the device to the USB of your PC/Mac, the RGB LED should turn green, try again if it's not green
+* Remove tweezers/scissors quickly while the LED is green
+* The LED should turn yellow, try again if it's not yellow
+* The device should be detected as USB drive
+* Format it to FAT32 if it's not formatted yet (you need to do it only once)
+* Write SVF file with firmware for EPM3064 and BIN file with firmware for STM32F103ZET to this drive, you can write both at the same time
+* The RGB LED should turn white
+* Wait for some time (~30 seconds for EPM3064 firmware, ~1 second for STM32F103ZET firmware)
+* The RGB LED should turn green if success, red on some error
+* Reconnect device to your PC/Mac
## Driver
-Under Windows the driver is usually installed automatically. If it doesn't, you can get the driver here: [https://www.st.com/en/development-tools/stsw-stm32102.html](https://www.st.com/en/development-tools/stsw-stm32102.html) - registration required but it's free.
