Was trying to adjust the Archipelago random seed to get something similar but can't come close, wasn't there a project a while back to produce maps based on supercontinents (it may not have been this game), looking for the layout close to https://en.wikipedia.org/wiki/Pangaea_Proxima
This map is primarily for 8 AIs (controlled via random LLM strategies) so doesn't have to be perfect, more for research.
