Talk to the person in the entrance of the Elder's house for Debug Menu. Disable the code after you've used it, and save your game if you want. When using the 'Debug' option, you'll spend quite a while leveling up. Leave the room and enter again before talking to the person for other debug options. Each time you use the 'Debug' option, it sets your EXP to 90,000 (Level 34), adds 1 of all types of magic, adds 35 Magirocks, adds 1 of several types of armor, and adds 1 of several different weapons. It will only add up to 8 of each item, for reasons that almost assuredly relate to using the option too often during debugging and the game glitching for the programmers.
