Believe it or not, this is a port of the Super NES game from 1997 - which was Europe-only - for the Game Boy Advance. Not surprisingly, this port is also Europe-only.
In the menu, the red bullet in the chamber is pointed at what you are highlighting, and the background will move towards what you are highlighting.
Normal is the easier of the two difficulties, while I want to believe that Difficult is the original Super NES difficulty.
The story begins with the newly-elected President of the United States granting general amnesty to all felons. This allows the Dalton Brothers, Lucky Luke's most persistent nemeses, to be free men, and not surprisingly, they start committing crime again the moment they get out. After being freed from prison, they rob the Yuma City Bank, which gets the attention of our hero Lucky Luke.
Yuma City
Left and Right moves left and right, Down ducks, A jumps, B shoots, and Up on the D-Pad can be used to shoot upwards with the B button. You can also aim diagonally upwards and fire in those directions, but you'll also have to deal with moving and shooting at the same time. If you press L, you can switch between walking and running, and that will allow you to aim diagonally upwards more easily.
If you press Up in certain spots, Lucky Luke will super jump to the platform above him, Rolling Thunder style. You'll need to be under the edge of a platform that is above Luke to be able to do this.
Your current ammo will be in the upper-left hand corner, You'll need to pick up six-shooter cartridges in order to get more bullets. The bullets left in your current cartridge will be in orange on the icon in the upper-left, and you'll reload if you have a free cartridge. You can have up to nine cartridges on stand-by at one time.
Your current amount of lives and health will be in the lower-left hand corner. Any lives that you pick up will only be good for the current stage; you'll be knocked back to the default of three lives when you reach the next stage. To get more lives, look for white cowboy hats throughout the current level. As for the starts, you have four hits, and when you run out, you will lose a life. Pick up stars to refill one unit of health if you get hit.
If you have maximum health, bullets or lives, you won't pick up the item that you already have maximum of if you move into it.
Enemies will pop out of windows and other things. Be ready to shoot them before they shoot you. If they shoot, duck or jump to avoid their bullets. The hands with the gun that poke out of certain areas are hard to shoot, as their hitboxes are pretty small, but you can hit them.
When you reach the well, Lucky Luke will notice that the well has been bricked up. Press A to stop reading the dialogue bubbles and get back to the game. When you're reading dialogue, a red X will flash where your ammo is; it will disappear when you get rid of the on-screen dialogue.
There are four playing cards that you can pick up in each stage that takes you to a bonus area. These playing cards were not in the original Super NES version. Any cards that you pick up will appear in the lower-right corner, but they will all be face down. You'll need to remember which cards you picked up as you go through each level. The bonus areas are not needed to beat the game, and you'll get nothing from them, but some of them are more beatable than others and there's a bit of satisfaction in beating them.
If you jump into the covered wagon shortly after the start of the level, you'll get the Ace of Hearts. Go left and jump to get it.
If you go inside any place that the game considers a room and then leave, all the enemies you defeated and all the items you picked up will re-spawn. This will allow you to get more bullets, health and lives.
Shoot down the haystack to drop it onto the see-saw. This will allow you to jump on the see-saw and get launched towards the rest of the level. When you do that, remember to head back and get the Ace of Spades.
Jumping on the vulture allows you to get the nearby extra life.
You'll find Rin Tin Can (originally named Rantanplan in the French language version) near a stick of dynamite, which you can collect. When you have dynamite, it will appear next to your ammo in the upper-left corner. You'll also meet the bank teller, who will tell you that the bank manager has been thrown down the well that has been bricked off. You'll need to head back to the well, then press R to light the stick of dynamite and lay it down while standing on the well. Back off so you don't get hit by the explosion, then go down the well when it's open. When the platform goes down, jump to the right when it stops so you don't drop into spikes, then head right and talk to the bank manager to free him.
After this, you can take the platform back up and jump straight up when it stops after moving upwards. Head back to the bank and jump onto the covered wagon to continue, then jump to the second level of the next building and jump to get your third card, the Ace of Clubs. The fourth card, the Ace of Diamonds, will be above the next building directly over the coffin. You'll need to jump on the platforms on the buildings further to the right to double back and get it.
The see-saw near the end is used to get another extra life, if you need it.
The boss here is a gunfight. Press A after being told to fire on the signal to get the dialogue off the screen, and when the mortician brings his hand down, fire your gun. After three bullets, you'll shoot the other guy's belt off and you'll beat him. You'll then find out from Jolly Jumper, Lucky Luke's horse, that the Dalton Brothers have started a mutiny at the prison in Casper. You'll need to head down to the prison and stop the mutiny.
The bonus stage after this level is a trip to the canyon. Move Jolly with Left and Right on the D-Pad, press A to jump and press L and R to lower yourself and grab dollars bills to your left and right respectively. You'll need to get through the canyon and collect all the dollar bills while also getting through the canyon without getting hit too many times. The amount of dollar bills you've picked up will be in the upper-left corner, while the amount of hits you have left will be in the lower-left corner. If you run into holes, rocks or cacti three times, the game tells you that you are unlucky. If you survive the canyon but fail to get all the dollar bills, the game will tell you that you avoided the canyon trap. The game will congratulate you if you survive with all 50 dollar bills, but you won't get anything else out of it.
