So I was able to open the wallet.dat file in the latest version of Bitcoin Core, when I do dumpwallet "~/wallet.txt" the file has a bunch of pub/priv keys in it. For example it has a line that says extended "private masterkey: xprivxxxxxxxxxxxxxxxxxxxxx" followed by 2,000 priv keys that begin with '5' or 'L' and the public keys beginning with 'bc1'. After those 2,000 pub/priv key pairs there are another 2,000 pub/priv keys pairs, priv keys that begin with '00' and pub keys that begin with '3'.

Example: Kxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2020-12-17T16:32:01Z reserve=1 # addr=bcxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx hdkeypath=m/0'/0'/696'

00xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 0 script=1 # addr=3xxxxxxxxxxxxxxxxxxxxxxxxxxx

any ideas?

Update on pywallet: Still couldn't get it to dumpwallet, stuck on this error:
