Super Cassette Vision - 32KB RAM Multicarts

You have most likely already seen this: https://team-europe.blogspot.com/2019/07/super-cassette-vision-32k-ram-multicart.html

This old design basically worked, but no matter what i did, it drained the battery within 3 days. So i had to look for another solution.

Basically only one of the 32KB games need the battery and this is POP & CHIPS for the HIGHSCORE table.

So i reworked the design to use F-RAM chips and now POP & CHIPS worked like a charm. But DRAGON SLAYER did not, this one only worked with the S-RAM chip. Luckily it looks like, it really only needs the RAM for gameplay and not for saving.

The conclusion is, we now need two cartridges:

The good thing, none of these two cartridges now needs a battery and the F-RAM cartridge will hold your data for at least 30 years.

DIP 5 & 6 are the DIPS for the RAM-Banks. Each cartridge has 4 of it. Which means you can save four different Highscore-Tables for POP & CHIPS if you want.

Both cartridges have a lot of space left, so many homebrew games could get designed for the Super Cassette Vision:

Here are the DIP-Settings for both cartridges
