Final Fantasy III: Can't Lose for Winning

When betting an item that is the same as your reward, you may not always receive it. Specifically, when you have 99 of it already, win or lose the battle, you'll lose the item you would've won. This patch fixes this rather quirky behavior with the Dragon's Neck Coliseum.

Urgency: Varies, it depends on the item, really.

Description:

When fighting a battle in the colliseum, your fee would be taken after the
battle is finished. From ZED's glitches and bugs guide:

Colosseum steals an item from your 99 stack if you win the same item you bet -

As the title says, get 99 of an item that you get back upon winning the fight
at the Colosseum, and proceed to bet it. Win or lose, you'll have 98 when the
fight ends (unless you get sneezed, run, etc.). It only happens in that
specific situation though. The easiest items to test this with are Fire
Knuckles, Tao Robes, and Trumps since you can buy those.

--------------------------------------------------------------------------------

What this patch does:

Instead of taking your fee after the battle, it takes it at the start of battle,
so if you were to win one back, you'll have a max of 99, and not 98.

The anti patches effectively remove this patch.

--------------------------------------------------------------------------------

Reasoning for this specific approach: (New section!)

At the Colliseum, Ultros mentions that betting a crappier item will cause Chupon
to just take it from you. In FF6A, however, Ultros mentions not to bet "cheap
crap, or Mr. Typhon'll hafta come 'n teach ya a lesson!" which isn't indicative
of how the game's behavior should be.

That said, it seems like this was the most logical approach to take. However,
that isn't to say there won't be a change to the patch.
