SNES PCB type database

Post by snescentral » Sun May 03, 2020 12:35 am

Over the past few months, I have been working on making the SNES PCB type listing that is on SNES Central more comprehensive. Today, I uploaded the first major update. I currently have 170 PCB boards documented. I have tried to make the list in order of function. On the pages, I tried to include the memory mapping that is found in Higan on each page, so that later on I can link the mapping to specific ROM images. I will be doing another update soon with more boards (specifically prototype boards). I've tried to include sample scans of every board, but for many I do not have scans of the back of the board. If there is any way I can make this more useful for devs, please feel free to let me know.

The code that I use to generate this database is on Gitlab.

I have a SHVC-BA3M-01 holding Super Metroid and a SHVC-1CB5B-01 that was modified before I got it but the back looks clean.

Remind me what size / DPI you want the scans at?

Generally speaking, I like to have a raw high resolution scan (i.e. 300 DPI), then I resize it to 700 pixels wide for the website.

http://snescentral.com/pcbboards.php?chip=SHVC-1A8F-01

this one seems to have incorrect information. It lists SRAM and RTC. It just looks like it was form data and these fields weren't deleted?
same goes for this one
http://snescentral.com/pcbboards.php?chip=SHVC-1A9F-01

Also, the 1L8B SA1 pcbs aren't listed?

SHVC-1A7M for Dezaemon is missing, too.
Sadly I don't own the carts missing otherwise I'd help out.

I never knew this even existed! Is the sram mapping linear?A0-A16 from the buss?

Yea, as it should be in LoROM.
Cart edge 40 is skipped and A15 upwards is connected to cart edge 41+

There is likely an error in my python script that makes the pages. I'll try to get it fixed soon.

If you have a scan of the PCB, I will add it. I only have included PCBs that I have scans of.


The stores in the city I am in are supposed to reopen tomorrow, I'll try to seek out a Dezaemon cart.

For completeness, would you be able to also take a picture of the back?

I will hopefully do an update this weekend.
