1Chip-03 versions does not have C46 installed.So left C14-C44 on the modding board unpopulated. 1Chip-01/02 versions have all capacitors C44-C47 on board.If you unsure, just left the footprints on the MultiAV free as these caps are optional. Make sure that you either have for each pin at the MultiAV just a single cap installed. There are also some footprints for 47pF ceramic capacitors on the modding board, namely C14, C24, C34 and C44. There are some 47pF ceramic capacitors at the MultiAV at pin 1 - 4, namely C44 (pin 1), C45 (pin 2), C46 (pin 3) and C47 (pin 4). In a 1Chip-03 (NTSC only) and in SNES2 models, this is the case by default. If you want to /CSYNC from the modding board you also have to ensure that pin 3 of the MultiAV is also free. In the SNES2, these pins are unused, i.e., you don't have to do anything here. remove R15, R16 and R17 from the SNES mainboard.In the big model you have to free pin 1, 2 and 4 from the MultiAV, which are the outputs of the red, green and blue component, respectively. Installation Preparation of the SNES Mainboard same as SNES_RGBAmp_wCSYNC just with footprints for S-Video completion in SNES2 models (Mini/Jr.)ĭo not use this board in a classical big model SNES.can be used in a 1Chip-01/02 if and only if the pin 3 of the MultiAV is freed (initially CSYNC (TTL) on NTSC and 12V on PAL models).mainly for 1Chip-03 boards and for SNES Mini/SFC Jr.Thank you very much! Installation Notes 1Chip-SNES (classical big model and SNES2 (Mini/Jr.)) If you want to go with (non-affiliate link), you can also use my affiliate link to support me. Or use any other PCB service you like :) Make sure that your PCB will be produced on a substrate of 0.8mm or thinner to make installation smooth and easy. Look at OSHPark: SNES_RGBAmp, SNES_RGBAmp_wCSYNC, SNES_RGBAmp_wCSYNC_SVid Take also a look into the notes provided there to ensure that you create your board according to your needs. Take a look into the BOM, where the components are listed. Each version differs a bit in its components according to its purpose.

There are three versions of the modding board available. The RGB Bypass Modding Boards for the SNES
