Project Nemesis is a fan driven website for games that use the One-Roll Engine (like Nemesis, Wild Talents, Reign and Monsters) or Chaosium's Basic Roleplay System (BRP) (like Call of Cthulhu) and the Delta Green setting.
This is a suggested set of rules to advise Keepers/GMs as to how to convert PCs/NPCs from CoC to Nemesis ORE. The main points are that:
1) It makes use of "la belle curve" a lot.
2) Because CoC uses just skill rolls and Nemesis uses stat+skill, Nemesis PCs stats come out somewhat less impressive stat-wise (1d to 3d), but lots of skills! This is okay because Lovecraft's protagonists tend to be less physical and more cerebral.
3) The skill list for Nemesis has been expanded to cover CoCs large number of skills.
4) An example of a conversion is included - see Harvey Walters in all his Nemesis ORE glory!
