All Dungeons After this aren't normally accessible. Enter these at risk of data corruption. I never beat Kyogre, but after completing Mt. Thunder Way at the end of the game (3rd Floor), the Kyogre losing cutscene was played and Kyogre was recruited. Mt. Thunder Way and other inaccessible dungeons Might mess with save data, so back up your save. Also, it appears that 0x33-0x44 are from Makuhita Dojo, but actually have floors unlike the dungeons seen in the Dojo. I have no idea what floor these dungeons end on, though. I got up to 15F. No items spawn in Dungeons 0x33-0x44 either.
