My friends, the SNES 2CHIP Edge Enhancer is 90% ready to go. I would like to write a few paragraphs about it, if that's OK. 1) My design is 100% all original. It's not based off of any forum post or esoteric website dedicated to any kind of video fixes. I broke SNES' DAC down internally via die shots to determine how the DAC was constructed and most importantly WHY it has the problems that it does with video sharpness. 2) The SNES Enhancer is compatible with ALL non 1-CHIP SNES systems. That means if your SNES is blurry, this works! The trade-off to this is that currently, it's a 5 wire installation. But if you look at the picture below, it's incredibly simple and will install very quickly. I felt that it was important to support ALL versions of the 2CHIP SNES, rather than making 4,000 different PCBS for 4,000 different revs. 3) The SNES Enhancer doesn't use any sort of video amplifier. Meaning, this isn't a boosted low-pass filter that will "sharpen" the video. I don't like that and let me explain why. For starters, it's bandwidth limited and the sharpening performance is predicated on the type of video content that the SNES' PPU is rendering. I decided not to make something that was going to perform badly or even oscillate depending on what sort of game's played. I've taken an entirely different approach and I'll be discussing it at a later time. But the long and the short of it is that I wanted to design a video appliance for the SNES that will work for ALL video content, evenly. The video output will be sharpened for all outputs. That means RGB, S-Video and Composite Video will all 3 benefit from this design. The PCB is a 5 wire install. Now, I could absolutely design version of this that are "console" specific that will just fit in. But the way I see it, it's 5 measly wires and in order to satisfy the broad spectrum of SNES revisions, I'm willing to accept this as the installation is incredibly simple. 4) This isn't a magical cure all fix for "noise". There are a plehtora of reasons why the SNES can be noisy. Part of the reason why I've waited so long to release this is I'm also in the process of working out some complimentary mods that will help clean-up/improve the picture quality of the SNES. Remember, these are analog video signals! 5) This wouldn't have been possible without @retrotink2 and @furrtek. Mike and I worked on the best ideas to edge enhance the SNES' video output and his input was integral. Furrtek helped me with analyzing the die shots of the 2CHIP PPU's DAC so that I could reverse how it works by how it was designed. This wouldn't have happened without his input and expertise, either. Anyhow, this installs super easily and I was able to bring the (B)ill (O)f (M)aterials down so that it's not incredibly expensive to make. I hope you guys enjoy this. It's my love letter and farewell to the SNES. Enjoy some of these 2CHIP screenshots of a launch model SNES fitted with the SNES Enhancer!
