CONNECT BY with a join, keeping the top joined record for the entire tree?

Question

Faced with a Groupe TABLE, and a Groupe_Role TABLE, i am trying to get a user's rights FROM Groupe_Role for each and every member in Groupe. However, the user's rights should be the same right as where we entered the tree.
Here are sample TABLEs, with my attempt at a query, which obviously does not work because the WHERE clause limits the records from the tree.
WITH
     Groupe
AS
      SELECT 1 Id, 'cupboards'      Name, NULL     Parent FROM Dual UNION ALL
      SELECT 2 Id, 'book-shelves'      Name, 1     Parent FROM Dual UNION ALL
      SELECT 3 Id, 'maps'           Name, NULL     Parent FROM Dual UNION ALL
      SELECT 4 Id, 'pictures'      Name, 3     Parent FROM Dual UNION ALL
      SELECT 5 Id, 'pegs'           Name, 4     Parent FROM Dual UNION ALL
      SELECT 6 Id, 'jar'           Name, NULL     Parent FROM Dual UNION ALL
      SELECT 7 Id, 'orange marmalade' Name, 6     Parent FROM Dual UNION ALL
      SELECT 8 Id, 'sticks'           Name, NULL     Parent FROM Dual UNION ALL
      SELECT 9 Id, 'dry leaves'      Name, 8     Parent FROM Dual
     Groupe_Role
AS
      SELECT 1 Groupe, 'Charles'     Member, 'Keeper'     Role FROM Dual UNION ALL
      SELECT 2 Groupe, 'Charles'     Member, 'Player'     Role FROM Dual UNION ALL
      SELECT 3 Groupe, 'Lewis'     Member, 'Keeper'     Role FROM Dual UNION ALL
      SELECT 1 Groupe, 'Alice'     Member, 'Player'     Role FROM Dual UNION ALL
      SELECT 3 Groupe, 'Alice'     Member, 'Player'     Role FROM Dual UNION ALL
      SELECT 6 Groupe, 'Alice'     Member, 'Player'     Role FROM Dual UNION ALL
      SELECT 8 Groupe, 'Alice'     Member, 'Player'     Role FROM Dual
SELECT
     Groupe.Id,
     Groupe.Name,
     Groupe_Role.Member,
     Groupe_Role.Role
FROM
     Groupe_Role,
     Groupe
WHERE
     Groupe.Id = Groupe_Role.Groupe
CONNECT BY
     Groupe.Parent = PRIOR Groupe.Id
START WITH
     Groupe.Parent IS NULL
ORDER BY
     Groupe_Role.Member,
     Groupe_Role.Groupe;The results i am looking for are as follows:
1 Alice      Player 'cupboards'
2 Alice      Player 'book-shelves'
3 Alice      Player 'maps'
4 Alice      Player 'pictures'
5 Alice      Player 'pegs'
6 Alice      Player 'jar'
7 Alice      Player 'orange marmalade'
8 Alice      Player 'sticks'
9 Alice          Player 'dry leaves'
1 Charles     Keeper 'cupboards'
2 Charles     Keeper 'book-shelves'
2 Charles     Player 'book-shelves'
3 Lewis      Keeper 'maps'
4 Lewis      Keeper 'pictures'
5 Lewis      Keeper 'pegs'How would i write such a query?

It's amazing what a little legwork will do:
10g: CONNECT_BY_ROOT Id Root_Id,
9i:     REPLACE(SYS_CONNECT_BY_PATH(DECODE(Level, 1, Id), '~'), '~')
WITH
     Groupe
