How to read these codes

MYSTERIUM (gb)

checked-yes =>Continue: After losing your last life, start a new game. Drop the Iron into the Pool of Fire to create the Glass Key, then go through the door. At the end of the hallway, rather than turning right, press [SELECT] and you should see a VITRIOLK on the ground. Pick it up and use it to continue from the level you were on when you died. =>Level Skip: On the map screen, hold D+B and press [SELECT] to drop down one level. =>Cheat Items: On the map screen, hold L+A+B and press [START]. The item PASS KEY (opens any door) will now appear in your inventory. Drop this into any pool and it will become DOWNLEVL (lets you drop to the next level of the game). Drop DOWNLEVEL into a pool for UPLEVEL (restart the current level), and drop that into a pool for SUPERPOW (almost invincible). SUPERPOW will revert to the PASS KEY when dropped into a pool. =>Full Pack: On the map screen, hold U+B and press [SELECT]. Your inventory will now be nearly full. Repeat this trick for a different set of items.
