Latest rivison PCB assembled and tested. So far looking good! everything is coming together

. Once I work out a nice way to showcase the project I'll film it in action soon.
However, I'm still not done yet! After going back and fourth on the idea for quite some time I've decided that without a multi RTC/EEPROM solution this project is incomplete due to following being reset when changing games:
- DIP settings (freeplay, demo sound, Screen pos/brightness, etc)
- High scores
- And most importantly: unlocks. A few CV1k games required some sort of criteria to be met (usually just a string of button inputs) to unlock an extra difficulty, stage or character. If you're someone who enjoys deathsmiles this could be quite annoying.
While none of this is really a huge deal, it seems unpolished to not have a solution for this. So, I've created and ordered yet another daughter board which will house 16 RTC/EEPROM chips. Unfortunately this chip is no longer produced so sourcing may unreliable and/or expensive. If anyone knows of a suitable modern replacement please let me know, i haven't had much luck searching around myself. Id much rather use something that can be sourced from mouser/digikey.
