F-RAM upgrade across a couple of N64 Controller Paks, no more batteries quietly erasing your saves. Revisited years later and redone properly, following nosIndulgences' research: the quick version can corrupt data in the long run, so this one adds a pull-up on the write-enable line.
Tea break upgrade. #N64 controller paks fitted with F-RAM. No more batteries for these boys. #Nintendo #RETROGAMING #consolemodding
Finally circled back to fix something here. As per @nosIndulgences' research (https://x.com/nosIndulgences/status/1831342825926951227), this is the proper way to do this mod, in order to avoid data corruption in the long haul. Sadly, I couldn't make this as neat as I wanted to, my 10K resistors are too small.
And here's the second pak. @misirajeduart.bsky.social was complaining so I opened up that one too in order to show that 0603 can work with a steady hand.
Also re-did the first one.
