An Open-Source HardWare (OSHW) recreation of the Super Nintendo Entertainment System (PAL)
The design tries to be a 1:1 recreation of the original SNSP-CPU-01 Rev5 and SNSP-CPU-1CHIP boards.
Some of the planned changes and improvements
- Replace the obsolete trimmer capcaitor with an in-stock one
- Replace the reset button with a regular mechanical keyboard switch
- Include an AV out connector board using mousebites
- Replace the U11 regulator (the old mitsumi one had a nonstandard pinout for reset monitors)
- Include controller port board
- Remove the CIC/swap it for a CIC replacement
- Region switch
- Replace the audio RAM
- Replace the S-CLK clock generator
-
Include RGB bypass mod
Tips if you decide to make this/get it made
The dimensions are 188x159mm.
If you decide to get it assembled I suggest only getting the bottom side with all the SMD components done and doing the top yourself. The bottom only has jellybean capacitors, resistors, diodes, transistors so it's not going to be very expensive.
For the top you will have to salvage the Nintendo components. The video RAM is still being made by S@Tech (HM62256). The audio RAM can probably also be easily replaced, I haven't looked into this yet. Feel free to open an issue about it.

Questions
How big is the SNSP CPU-01 PCB?
It measures 215.8 × 159 mm and has 2 copper layers, 4.69 mm thick.
What parts does the SNSP CPU-01 use?
400 parts, built around the LM324, L7805, DAN202 and DAP202. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SNSP CPU-01 KiCad files?
From the stonedDiscord/nonSNES repository on GitHub, at the commit this page was made from: the board is SNSP-CPU-01/SNSP-CPU-01.kicad_pcb and its schematic SNSP-CPU-01/SNSP-CPU-01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SNSP CPU-01 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
