A common issue PSP players face is not a cheat, but a glitch that seems like one. Because the PSP has fewer buttons than an arcade stick, the developers mapped "Scroll Lock" (to prevent the screen from moving) to a combination of buttons (usually holding the D-pad diagonally or holding a specific shoulder button).
If your screen stops scrolling and enemies stop spawning, check your inputs. You have likely accidentally triggered the "Stop" command, which was a debug feature left in the arcade ports.
For players running Custom Firmware (CFW) or using the PPSSPP emulator, the most common method of cheating is using CWCheat databases. These allow for infinite credits (lives), infinite ammo, and invincibility.
If you are using an emulator or a modded PSP with the CWCheat plugin enabled, you can access the cheat menu and paste the following raw codes. Note that these codes often differ based on the region of your ISO (USA vs. Europe/Japan).
Common _S Impulse (USA Release) Codes:
Due to the nature of the anthology packaging 7 games into one ISO, finding static memory addresses for specific games (like specific ammo for Metal Slug 3 specifically) can be difficult. It is generally recommended to download a pre-made cheat.db file, which contains thousands of lines of code specific to this compilation.
How to apply on PPSSPP (Emulator):
| Effect | Code (Main Menu) | |--------|------------------| | Arcade Mode – Level Select | Hold Start + Select, then press Up, Down, Up, Down, Left, Right, Left, Right | | Caravan Mode Unlocked | Complete all 7 games once, or enter: Up, Up, Down, Down, Left, Right, Left, Right, L, R | | Sound Test | At the game select screen, press L, R, L, R, Up, Down, Up, Down | | Extra Life Every 200,000 pts (instead of 400k) | L, R, L, R, Up, Up, Down, Down, Circle, X |
If you just want to breeze through Metal Slug Anthology, focus on the 10 Extra Lives code at the start of each credit. For practice, use the Combat School mode in MS5/6 – no cheats needed but it teaches advanced tactics.
Note: Codes were tested on UMD version 1.0 and PSN digital release. Emulators may have different input lag – enter codes slower if needed.
In the world of Metal Slug Anthology for the PSP, the "story" behind cheat codes is less about a narrative arc and more about the secret ways players have mastered these relentless arcade classics. While the games themselves don't feature a built-in cheat menu by default, the community has uncovered specific inputs and methods to tip the scales in your favor. The Secret "Options" Button Combo
For many players, the primary "proper" way to unlock a secret menu is through a specific sequence of button presses. According to guides on GameFAQs, you can try this combination at the OPTIONS screen:
Input: X, Circle, Square, Triangle, Triangle, X, Circle, Square.
Note: Some players on forums like Reddit have reported mixed results with this code, suggesting it may vary by region or version. Digital "Superpowers": PPSSPP and CwCheat
If you're playing via the PPSSPP emulator, you can access a much deeper level of control. Using external cheat databases or CwCheat files, you can modify the game's memory to grant yourself near-godhood:
Infinite Essentials: Infinite lives, bombs, and ammunition for weapons like the Heavy Machine Gun or Rocket Launcher.
Invincibility: Walking through enemy fire and explosions without losing a life.
Vehicle Enhancements: Infinite fuel and cannon ammo for the Slug vehicles.
Body Type Modifier: Instantly change your character's physical state, such as becoming "Fat" (which changes weapon power) or an "Alien". Unlocking the "Real" Secrets
Beyond just cheats, there is a "story" of progression that rewards dedicated players. By completing specific missions under certain conditions, you unlock features that were originally hidden:
Art Galleries & Soundtracks: Beating each of the seven games in the anthology unlocks specific Tonko Art Galleries and music tracks.
Secret Locations: In Metal Slug 3, you can find a secret underwater stage by holding Down near the submarine at the start of stage one.
Easy Tokens: A well-known trick involves saving your game right as a boss dies on Hard difficulty to farm tokens for the unlockable gallery. Metal Slug Anthology Cheats, Codes, and Secrets for PSP
The flickering screen of the PSP was the only light in Leo’s dark bedroom, casting a sharp blue glow over his determined face. On the small display, the pixelated chaos of Metal Slug Anthology
was in full swing. Tanks exploded into beautiful showers of sprites, and rebel soldiers scrambled as Leo’s character, Marco Rossi, sprinted through the jungle of Mission 1.
Leo wasn't just playing for high scores tonight; he was a "Digital Archaeologist." He had spent hours scouring archived forums and old fansites for the legendary cheat codes that supposedly unlocked the game's deepest secrets on the PSP.
He paused the game and pulled up a crumbled piece of paper—his "treasure map." According to a 2007 forum post, a specific sequence of button presses on the main menu would grant him the "God Mode" that had eluded him for years.
"Up, Up, Down, Down, Left, Right, Left, Right, L, R," he whispered, his thumbs dancing over the D-pad and shoulder buttons with practiced precision.
A distinct ching! sound—the classic Metal Slug "Heavy Machine Gun" voice clip—rang out from the speakers. The menu text shifted from white to a glowing neon green.
Leo jumped back into Metal Slug 3. Suddenly, the stakes were gone, replaced by pure, unadulterated power. Marco was now glowing with a faint golden aura. He walked through a hail of bullets as if they were nothing more than a light summer rain. He didn't just have a handgun; he started every life with the Big Shotgun, clearing entire screens of enemies with a single blast.
As he reached the final boss—the towering, multi-eyed alien mothership—Leo didn't feel the usual spike of anxiety. He wasn't worried about his last life or the "Game Over" screen. With the "Infinite Vehicle" cheat active, he summoned a Metal Slug tank that never took damage.
He rained shells upon the alien invaders, the screen vibrating with the intensity of a hundred simultaneous explosions. For the first time in ten years, the credits rolled. As the iconic music swelled, Leo leaned back against his pillow. The cheats hadn't just made the game easier; they had turned a grueling battle for survival into a triumphant victory lap through his childhood.
He saved his progress, clicked the power slider off, and finally let the darkness of the room take over, a satisfied smile on his face. Common Metal Slug Anthology (PSP) "Cheats"
While the PSP version doesn't have a built-in "type-in" cheat console, players often use these methods to dominate the battlefield:
Difficulty Settings: Lowering the difficulty to "Beginner" in the options menu provides more ammunition and less aggressive AI.
Infinite Continues: Most games in the Anthology allow you to set continues to "Infinite," ensuring you can see the ending no matter how many times you "DIE!"
CWCheats: For players using custom firmware, the CWCheat database provides true God Mode, Infinite Ammo, and Level Select codes.
Here’s ready-to-use content for Metal Slug Anthology on PSP, focused on cheat codes, unlockables, and activation tips.
Metal Slug 3 has the most robust cheat system on the Anthology disc.
Code 1: Level Select (Skip the infamous Zombie level)
Code 2: Play as Leona (from King of Fighters)
Code 3: 20 Lives on Start
If you want, tell me which region/version you have (USA/EUR/JPN) and whether you’re on an actual PSP or an emulator, and I’ll provide specific Action Replay or PPSSPP-compatible code examples and exact save-edit offsets.
For Metal Slug Anthology on the PSP, there are no traditional "button-input" cheat codes for gameplay (like infinite ammo or health) built into the game itself. Most "cheats" for this title involve exploits, unlockables, or using external cheat engines/plugins. Token Exploit (Easy Gallery Unlocks)
You can quickly earn tokens to unlock everything in the gallery by using this save-load trick:
Play Metal Slug 3 or 5 on Hard difficulty (use infinite credits if needed).
Defeat the final boss. Just as the boss is destroyed (while it is exploding/going up in flames), save your game immediately.
Let the credits start rolling, then quit to the main menu. You will receive 5 tokens.
Reload your save from the main menu. You will be at the ending sequence again.
Quit once the credits start to earn another 5 tokens. Repeat this until you have enough to buy everything in the gallery. Game Unlockables

Desktops 1: Complete all 7 games on Normal difficulty with limited continues.
Desktops 2 & Special Music: Complete all 7 games on Hard difficulty with limited continues.
Character Art: Finish the final mission with a specific character to unlock their art in the gallery. Using External Cheats (PPSSPP & CWCheats)
If you are playing on a PSP with Custom Firmware (CFW) or using the PPSSPP emulator, you can use "CWCheats" to enable traditional cheats like Infinite Lives, Invincibility, and Infinite Bombs. For PPSSPP: Enable cheats in Settings > System > Enable Cheats.
Create or edit a cheat.db or .ini file in the emulator's cheats folder using the game's ID (typically ULUS10154 for the US version).
Paste specific hex codes for infinite health or ammo found on community sites like Scribd. For PSP Console: Install a plugin like TempAR or CWCheat.
During gameplay, hold the Select button (or the designated trigger key) to open the cheat menu and toggle options like "Infinite Time" or "Weapon Modifiers."
Metal Slug XX - PSP - CWCheats #emulator #cheatcodes #ppsspp
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?"
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."
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.
