c´est la première que j´ai trouvé!!!
-First, go to Elysia SkyTown and enter the Chozo Observatory (the location where you had to get the first of the bomb fragments). A phazite plate will be on the side of the platform column on the floor. Shoot through it to find a touch panel to activate.
You´ll then have to navigate the bomb-slot maze on the upper walls -- use your head and the Spider Ball! When all the slots are bombed/activated, your map data will now show Xs and Os. X indicates pickups you´ve acquired, and O indicates pickups yet to be found. If you want those bonus endings and/or the pride in fully completing the game, get ready to go hunting!
