I had created a mnemonic seed and address using MMGEN wallet but forgot to store the mnemonic seed, but did store the bip 32 root key by using the mnemonic seed on Ian colmen

Now I want to derive the same address using a derivation path and bip 32 root key. can you please tell me what would be the derivation path, since it is mentioned in the wiki, that the wallet is deterministically deriving its keys, but uses a non-hierarchical scheme differing from the BIP32.

Please help me if anyone has any idea which derivation path they are using.
