Hello guys, I read some nice threads here about getting the best RGB possible from the different SNES revisions. I thought I'd share my story on a mod I found on 2 of my SNES as some of you may be interested. I live in Thailand, where most retro consoles were imported and PAL modified. I have 2 US SNES (SHVC-CPU-01 and SNS-CPU-GPM-02) + Super Famicom (SNS-CPU-GPM-01). All of them had very low sound output due to bad capacitors. When I fixed them I noticed those different mods. The SNS-CPU-GPM-02 is a simple mod as you have a PAL/NTSC jumper on the back of the PCB + the 4.43 PAL xtal. On the other 2 I have a separate PCB with a CX1145 and the 4.43 xtal. While I decided on the US SNES to take off the mod, I kept it on the SFC to make some video comparisons. Well I was pleasantly surprised to see that all the jailbars and image defects I had using the original encoder were not showing up with the CX1145. The picture is really crystal clean. I took a few hi-res pics of the mod for those interested: https://plus.google.com/photos/1041...ms/6045568895116771361?authkey=CP3WqvfWm_fldQ The pics shall help you out to replicate that circuit, notice that the CSYNC pin on the BA-6594AF is lifted. If you need more info or details, let me know. The last 2 shots were taken on US SNES then SFC but unfortunately I couldn't properly render the jailbar effect as it really is.
I would be very interested in tryin this cxa1145 mod to see if video quality can improve, someone can translate the photos in schematics?? me no!
Sure, it's interesting. The thing is that there are many mods for SNES video and without schematics, this one isn't enough material to work with. But first of all: Which defects does it fix? RGB? FBAS?
I think the aim is to have a cleaner rgb signal than the blurry snes one, what other video snes mods you know? I would try everything to get a better video output
https://www.google.com/#q=site:assemblergames.com+THS7314 The blur is inherent to the SNES. There are 2 versions of the console and the newer (1Chip) model is a lot sharper. All the existing mods are about fixing problems like the "SNES dark vertical line" or muddy image quality from the aging video encoder.
