There are a few reasons people may want to do this, but most 1CHIP users wouldn’t need to: Pre-assembled THS7374 amps: If you have a 1CHIP-03, you’ll want to consider using a sync-on-luma cable, restoring the entire circuit on the motherboard, or using an RGB bypass board that includes the full csync circuit.Įven though the 1CHIP consoles already output high quality RGB, you still might want to bypass the onboard amp and use a different one.
I’ve been able to restore csync on these consoles by using a simple jumper wire, however that doesn’t seem to be the best solution, as it’s missing circuitry found in the other 1CHIP revisions: You can use these consoles without a modification, simply by using an RGB SCART cable that gets sync from luma. The “03” revision does not have csync run to the multi-out. There are three revisions of the 1CHIP motherboard: SNS-CPU-1CHIP-01, SNS-CPU-1CHIP-02 and SNS-CPU-1CHIP-03. – That’s it – Click the picture for a full-sized view: – Make SURE to trim any of the resistors that are sticking out the other end. – Solder three 750 Ohm resistors to the holes and then solder all of them to the ground point shown in the picture. – Locate the “R6”, “R7” and “R8” RGB via holes – Disassemble the 1CHIP console and flip the board over. In fact, it’s possible that this is a big part of the reason some people think SNES Mini’s look better then 1CHIP’s. This can result in an image that’s slightly washed out, or shows signs of “ringing”. I have a page dedicated to this, with as much information as I could find: Īll 1CHIP consoles output a signal that’s too bright. You’ll have to start by finding a SNES with the correct motherboard though: While all of the 1CHIP revisions output RGB without a modification (only the correct RGB SCART cable is needed), there are a few things you can do to enhance the performance of the console.
They appropriately labeled these motherboard revisions “1CHIP”. In 1995, Nintendo released a revision to their Super Nintendo consoles that combined the system’s two video chips into one.
This page has information on Super Nintendo consoles that have the “SNS-CPU-1CHIP” motherboards, which are known for their higher quality video output.
