Before BIP43 and BIP44 came out a lot of older wallets uses m/0'/C/I where C is 0|1 for change and I is the index.

For script they mostly used compressed P2PKH.

A friend of mine has some coins on the pre-BIP44 wallet with a Japanese BIP39 phrase.

We noticed this wallet supported Japanese, but not his path...

Alternatively, a way to input a custom path is also acceptable.

Thanks for your help!
