I dont have my nem address - I have old balance in that address

I dont have my nem address - I have old balance in that address

I do have the private key and I do have some letters of my nem public address (I have 4 groups of 6 letters each and then i have the last 4 letters too of that address starting with NA). The private key and these letters of the public address are written on paper since i felt paper and offline was the safest.
It was a nano wallet if i can remember correctly

I would like to know the balance of that address and transact too. Is there any way?

Also my address is quite old and i am not sure if the same wallet key will apply or if there have been forks and airdrops along the way during all this while. I heard about this XYM - what is that? Was my xem converted to xym? Will the keys be the same?

I may have have a wlt stored file somewhere. Can i get the balance without that file? If i find that wlt file then can i get the balance xem and xym?

to restore from private key:

  • get and install wallet Wallets - NEM
  • Sign up > Private key wallet option
  • Choose mainnet
  • Choose wallet name and password
  • Provide private key from backup
  • Create and login
