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

Made to fix glitchy graphics on certain famicom disk system adapters. Place over first row of pins on back of pcb and very left rows, both top and bottom pins should line up then solder the vias to the pcb. Resistor arrays are two CAY16-472J4lF 4 resistor 4.7k ohms. Untested so let me know if it works and the fit is right.

special thanks to citrus3000psi and extrems for the original design as well as emu_kidid. This is my version of the sd2sp2 adapter for gamecube with a few changes and upgrades of my own. One is i made the shape slightly different. Two i removed the solder resist from the pins for better conectivity, like a cartridge would have. Lastly, I use a spring loaded connector for the card which i feel holds the card in place better, I dont like the standard holder that is on all the other ones. It’s kind of hard to solder the pins but pin one and 8 dont need solder, just 2-7. The cap is a 22pf 0805 package, the or gate is a sn74ahc1g32dck3 and the connector is a mem2061-01-188-00-a

Order .8mm for best fit. A simple pcb to defeat the cic lockout in a frontloader nes instead of using two wires. this goes on the bottom of the cic chip and the 74hcuo4 ic. The top of the pcb has the traces and no writing that side goes up. On the frontloading nes, locate the cic and 74huoc inverter, the inverter will be to the right and down from the cic. Place this board to where the topmost right hole goes on pin 8 of the cic(it will be the last pin on the top right of the cic) it should line up over pin 7 and 8 of the cic, and pin 1 and 2 of the inverter. Then simply solder the 4 vias in place and done. No need to solder the holes without copper rings on them.

A simple pcb to add s video to your snes jr cleanly. Place the empty multiout holes from the pcb(the holes with no via metal rings) onto the rightmost pins on the snes multiout, there should be 1 row with no connection on the snes to the very left(last row of pins on snes multiout. Only solder the metal via pins on pcb to the snes multiout pins, then run 2 wires from the encoder(pin 12 chroma pin 17 luma) and run it to the right of the motherboard on top and around to the pcb on the back. the big cap is a 3528 tantalum 220uf cap, stripe facing the y pad(stripe is positive). the 3 other components are 0603 package. the resistor on the y line under the y pad is 75 ohm, the cap next to that under the c pad is .1uf, and the resistor closest to the multiout holes is also 75 ohm.
