Hold Up-Right + A + B when you are recuiting soldiers or equipping items. Garett MUST be highlighted when the buttons are pressed. All items will be available (including the Dragon Slayer) except for Warsong.
Note: This trick only works in the Japanese version. Also note that your cash will be reduced to zero if you do this.
Level Select
This trick is a bit complicated, but it does work.
Begin a game.
Press A to reduce the map.
Move the cursor to the upper left-hand side corner of the screen.
Move the cursor one space right and one space down.
Hold B until a scenario number appears. Press Up and Down to pick a stage.
You will begin the stage using the commanders you had when you entered the code.

Here's a list of magic items and some of their effects.

Secret Character Class
I'm not sure how secret this is, but it's not mentioned in the manual. When a female Magic Knight reaches level 10, it can turn into a Ranger. The only problem is that a Ranger can't have soldiers of any sort. However, this isn't really a problem as she's EXTREMELY powerful.
Sound Test
To access the sound test, follow the Level Select instructions but enter the code on the normal map (don't reduce it.)
