The Code Isn't Working

The Game Crashed Metal Slug 3 is notorious for crashing on the PSP when too many cheats are active at once (e.g., Flamingo + Level Select + Infinite Continues). Solution: Enter only one code per session. Save often using the Anthology’s built-in suspend save (press Home > Save State).

I Lost My Save File No surprise. Some cheat codes permanently alter the save file header. Always back up your ULUS-102110001 folder from your PSP’s SAVEDATA directory to your PC before experimenting.

These entries have simpler cheat structures. For both:

Infinite Continues (Universal for MS4 & MS5)

Play as Trevor or Nadia (MS4)

For over two decades, the Metal Slug series has stood as a titan of the run-and-gun genre. Known for its hand-drawn pixel art, over-the-top explosions, and a unique blend of grim warfare and slapstick comedy, the franchise holds a special place in the hearts of arcade purists. When SNK Playmore released Metal Slug Anthology for the PlayStation Portable (PSP) in 2006, it was a dream come true. Packing seven complete arcade classics (Metal Slug 1, 2, X, 3, 4, 5, and 6) onto a single UMD, it was the ultimate portable collection.

However, there is a well-known catch. Metal Slug games are notoriously brutal. They are designed to drain quarters from arcade-goers, meaning your player character dies in a single hit. With limited continues and the small screen of the PSP, even veterans can find themselves stuck in a perpetual loop of "Mission Failed."

This is where cheat codes enter the fray. While Metal Slug Anthology does not have a traditional "menu" for cheats, the PSP version retains the classic button combo input systems from the arcade originals. By inputting specific sequences on the D-Pad, analog stick, and face buttons, you can unlock infinite continues, select any mission, turn enemies into flamingos, or even raise the dead.

Warning: Most cheat codes in Metal Slug Anthology require specific timing. Inputting them too early or too late will fail. Also, save your game before entering codes, as some may disable trophy/achievement-equivalent progress (though PSP has no trophies, it can affect save file integrity).

It was a lazy summer afternoon, and 17-year-old gamer, Alex, was lounging on his couch, flipping through his collection of PSP games. He stumbled upon the Metal Slug Anthology, a compilation of the classic run-and-gun action games. Alex had always been a fan of the series, but he had never played the PSP version before.

As he booted up the game, Alex noticed that his friend, Ryan, was over at his house, watching TV in the living room. Ryan was also a gamer, and Alex knew he would be interested in playing Metal Slug. He called out to Ryan, "Hey, man! I'm playing Metal Slug Anthology. Want to join me?" How to enter: Wait for the title screen

Ryan walked into the room, and they decided to play the game together. As they started playing, Alex realized that they were having a blast, but they were also getting frustrated with some of the tougher levels. That's when Ryan mentioned that he had heard about some cheat codes for the game.

Alex's eyes lit up, "Cheat codes? What kind of cheat codes?" Ryan smiled mischievously and pulled out his phone. He started searching online and found a website with a list of cheat codes for the Metal Slug Anthology on PSP.

The first code they tried was the "Infinite Continues" code: Up, Down, Left, Right, X, Square, Circle, Triangle. They entered it in, and to their surprise, it worked! They could now continue playing from where they left off, even if they died.

The next code they tried was the "All Weapons" code: Down, Left, Up, Right, X, Circle, Square, Triangle. With this code, they had access to all the weapons in the game, including the powerful Slug-4 and the trusty Shotgun.

As they continued to play with the cheat codes, Alex and Ryan felt like they were invincible. They breezed through levels, defeating bosses with ease. They even unlocked some of the game's secret characters, including the mysterious Fio and the tough-as-nails Eri.

But as they played on, Alex started to feel a twinge of guilt. Using cheat codes wasn't exactly fair, was it? He looked over at Ryan, who was still enthusiastically blowing through levels. "Dude, do you think we should stop using these cheat codes?" Alex asked.

Ryan paused the game and thought for a moment. "I don't know, man. It's just a game. We're having fun, right?" Alex nodded, and they continued to play, but with a newfound appreciation for the game's original challenges.

As the afternoon wore on, Alex and Ryan decided to put the cheat codes aside and play the game the way it was meant to be played. They started fresh, without the codes, and discovered that the game was even more enjoyable without them. They had to work together, using their skills and strategy to overcome the challenges.

As they finished the game, Alex turned to Ryan and said, "You know, that was way more satisfying than using cheat codes." Ryan nodded in agreement. "Definitely. Let's do it the hard way from now on." Code 2: Play as Eri or Fio (Secret Characters)

From that day on, Alex and Ryan made a pact to play games the way they were meant to be played – without cheat codes. They still had a blast playing Metal Slug Anthology, but now they felt a sense of accomplishment and pride in their gaming skills.

Metal Slug Anthology includes 7 classic arcade games (Metal Slug 1, 2, X, 3, 4, 5, and 6). Unlike modern games with a cheat menu, these codes are legacy arcade-style button sequences entered during gameplay.
