SNES Jr. Installation Guide

Basic Installation:

The basic installation procedure for the SNES Jr. offers the core features that most users will want from their SNES RGB Bypass + Dejitter mod on the SNES  Jr. These main features include:

– RGB Bypass. This part of the mod adds RGB output to the SNES Jr.

– Csync Restore. This part of the mod adds Csync output to the SNES Jr.

– S-Video Restore. This part of the mod adds S-Video output back to the SNES Jr.

– Csync Dejitter. This part of the mod adds the dejitter functionality to the SNES Jr. Csync output.

Basic Installation Procedure:

Step 1: Remove the four gamebit screws from the SNES Jr. shell. You need to use a 4.5mm gamebit screwdriver for this.

Step 2: Remove all 7 Phillips head screws from the motherboard and remove the motherboard from the shell.

Step 3: Locate and trim the legs of the capacitors and the 7805 regulator on the back side of the SNES Jr. motherboard near the AV Multi Out port.

Step 4: Remove the crystal (X1) from the motherboard. There are a few ways to do this depending on what soldering equipment you have available. The way I do it is to use a large soldering iron tip and add plenty of extra solder to both legs of the X1 crystal keeping the solder molten across both legs. Usually the X1 crystal will fall off of the motherboard under it’s own weight if you can keep both legs hot enough. If you do not have a large enough soldering tip, you could remove the solder from the legs of X1 using a solder sucker, desoldering gun, or desoldering braid. Do whatever you are comfortable with.

Step 5: Place the SNES RGB Bypass + Dejitter mod onto the pins of the AV Multi Out as shown in the photo below.
