Firmware for Programmer

Microcontroller on the programmer PCB needs a firmware (written by micro) in order to work properly. Use the firmware provided in this subfolder or the one in the original source. Please make sure to set the fusebytes correctly.

Program the CDCE913 (DFO) on the MultiRegion PCB

Use the GUI (software written by micro) in order to program the PLL. This is required in order to get the DeJitter and on-board color carrier switch working. To program the PLL perform the following steps:

• Set V-target jumper on programmer to 5V
• Connect programmer to modding board (make sure that the connector is matched otherwise you may harm your modding board!)
• Connect USB cable to Windows PC
• Launch programmer app
• Load hex-file for the CDCE913 by clicking on Load Configuration File
• Click on Program CDCE9xx button
• Disconnect everything once finished

modding board installed in SNES
