based off the mikemoffit and yoshiyukiblade circuit but with my own twist and extras, here is a sharpening circuit for the 3 chip (or 2 chip if you want to call it) snes. Works with every version. Untested pcb so if used please tell me if the fit is right and everything is all good. This is a combo bypass and sharpener in one and can be used to fix the s video and composite too. You can use a ths7373,7374, or 7376 chip but if using the 7374 short the jumper. For the chip components, the top component above the top jumper pad is the .1uf cap the bottom component under the bottom jumper is the 4.2k resistor This isnt the best way to sharpen the snes, just a cheap fun project i did i see alot of want for this. I would buy voultars if you want a legit right way to sharpen the snes but try this if interested. Remove the input and output resistors and transistors(there are plenty of guides now) and use 24-30 pf caps are the first components after the chip then 450-470 ohm resistors are the output resistors after the caps. For the encoder section, all 1k resistors for the first row, then 150 ohm next, then the .1uf caps are last. the castellated vias are to line up with the right side of the caps of the cpu 01 snes(first model, need to remove the caps from the snes first). the encoder pads are to send the outputs of the rgb to the encoder of all other 3 chip snes consoles. All components 0603 size. My email is [email protected] message me with any questions and ill walk you through it if you need or I can do installs for a price
