Then play these 5 quests again, in this order, Secret Delivery, Claiming A Stake, Grand Squall, The Value Of Money and The Lost Bride. On each quest, before you teleport down to Ragol, make sure that you speak to every character in the Lobby and outside the lobby. Someone will talk to you about a group called WEAPONS that you can join if you collect Five emblems. Each will give you an emblem.
Once you have collected all the emblems, go back to Secret Delivery and talk to The Boss - who turns out to be the woman in the apron from the quest "The Value Of Money" she will be at the shops. She will give you AKIKO'S FRYING PAN - a secret weapon that's not that powerful really but funny to use.
Now you can find Enemy body parts which you can change into weapons. To do so, make sure you have that rare item in your character's inventory, and go on the Unsealed Door quest. Again, do not teleport down to Ragol, but speak to Montague (the guy wearing a big yellow hat a bit like Jamiroquai) who stands to the right hand side of the teleporter that takes you to the Principal.
Here's the weapons (and body parts necessary) that I've discovered to date:
DELSABER'S BUSTER from Delsaber's claw
GOBOOMA'S CLAW from Gobooma's hand
RAPPY'S FAN from Rappy's wing
HILDERBEAR'S CANE from Hilderbear's head
G-ASSASSIN'S SABRES from Grass Assassin's Arms
AKIKO'S FRYING PAN given to you by WEAPON' Boss
Make is so the Weapon shop is at Buy/Sell. Now hit START. Select BUY and Item Pack and hit A. Now select the cheapest weapon you can use and Items and hit A. Select Yes and the item you have equipped. Now just keep hitting A until you are either out of money or full. Now you can exit all of them. Look at your item menu. You will have a lot of the items you bought equipped. Now to equip the other weapons you first unequip one of the weapons you bought and then equip a weapon you had already. Keep doing this as much as you want. If you want to equip more weapons....sell the items you bough that you dont have equipped and buy more the same way.
Now go to F1 and see your new weapon. It uses the motion of your last equipped weapon. Say if you want a animation of a Double Sabe you would remove it then reequip.
NOTE- This can be also done with Armor and Shields. Just instead of the weapon shop you use the Armor shop. Also you have to do this for every new game you are in. It only works while you are in the game. It doesnt save.
