i have a lot of wallet dats from 2012 and nothing will sync. how do i get my dogecoin, unobtanium and other coins back with my old dat files?

first try to figure out what type of wallet were you using. was it the official full node (eg. Dogecoin Core) or was it a light wallet (eg. MultiDoge) or web wallet,...

then find out the website of said altcoin and download the latest version of that wallet and try importing your wallet.dat files in them and see if it works. it should since good developers make their wallets backward compatible. if you had issues, try downloading the old version of the wallet (eg. https://github.com/dogecoin/dogecoin/releases) and import your wallet.dat there but just export your private keys and import them in the latest version of the wallets.

if nothing worked you may be able to find tools on github to read the wallet.dat file only and  try to extract the private keys in order to import them in newer versions. if you have considerable amount you can even pay someone to code something for you real quick. but be careful what you use and don't trust anyone easily.

If dat files do not fit to new particular wallet you should export your private keys using the old one, create new wallet and import private keys there.
