Patch:V Card
The V Card is a special item in Keen 5 used to open 'V Card doors'. They do nothing but sit and animate like a regular item and as such patches relating to them can be found on the page Patch:Items.
The V-card also has two unused actions of its own, suggesting that it was intended to be a special type of item distinct from the others.Patches for these two actions are included here, but it should be noted that they will not affect anything in the default game.

Don't lose V card on opening a door
This patch prevents Keen from losing any V cards he has when opening 'V Card doors'. This means once he gets a card he can use it as many times as he wants in a level.

Don't lose V card on starting a level
This patch prevents Keen from losing any V cards he has when starting a level. His keygems will still be affected. See also Patch:Level start.
| Patch: Keen 5 |
|
Don't lose keygems or V card
This patch stops Keen losing not only his keygems but also his V card on leaving a level (but again, not when dying.).
| Patch: Keen 5 |
|
Have one or more V cards when starting a level
This patch ensures Keen always has a V card when starting any level, including the map. He will be given the card whenever he leaves a level, but will lose it when he dies and retries a level. The value here can be other than 1 if desired.

Give\take something instead of a V card on level start
This patch alters what is affected at level start so it is not necessarily a V card. This variable can also be set to other values aside from 0 or 1; in this case keen will start all levels with 10 ammo. Notice that if Keen dies he will lose the V card but not what is given here.

V card unused actions
As noted above the V-card has two unusued sprite actions. The following sections contain patches for these but again it should be noted that these will not affect anything in the game itself.
Sprite Actions
There are two central item actions, both do the same thing, they leave an item sitting, waiting to be collected. This mirrors almost exactly the default item actions in all properties. Since the V-card is spawned as a regular item this special V-card loop is never used in the game.
Keen 5 Actions: $1982W #Card 1 $19A0W #Card 2

Sprite Behavior
Unlike regular items the V-card has its own special behavior. This lets it fly through the air and land on the ground to become a regular item.
| Patch: Keen 5 |
|
Behavior code
This is the complete, if short, behavior code for the V-card. On the first line it checks for floors, if it finds them then the Card's action is changed to that of a regular sprite. The purpose of this was to make the V-Card spawn somehow, fly through the air and become a regular item when it hit the ground, much like what the Blooglet gems do in Keen 6.

|
Speed and Jump Height
The V-card was intended to fly through the air, but its unused actions do not have any speed.
| Patch: Keen 5 |
|
Sprite collision
The unused V-card actions had no sprite collision as getting the card was determined by Keen's collision, as with most items.
| Patch: Keen 5 |
|
Animations
It seems that the V-card's animations were intended to be set in the same way as item animations in general, so the unused actions have no animations.
| Patch: Keen 5 |
|
Sprite-tile interaction
The unused V-card actions use a generic 'raw the sprite' tile interaction code that does nothing special. Oddly, while the card was intended to land on floors, this is checked for in its behavior code rather than its tile interaction.
