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. Part 5: Are Cheats Ruining the Experience? Philosophical question: Metal Slug is about mastery. The pixel-perfect jumps, the hidden prisoners, the satisfaction of beating a boss without losing your &%$# tank. Cheats, by design, bypass that.
For purists, use the cheat to practice the final boss repeatedly. Use the 10 lives code to learn enemy patterns. Then, turn off cheats and play for the high score.

From turning the battlefield into a flamingo parade to giving yourself 30 continues, these codes open up the game for casual players and allow veterans to skip to the levels they love most. Metal Slug Anthology Psp Cheat Codes
However, Metal Slug Anthology on the PSP has a legitimate excuse for cheating: . On an arcade monitor, you see incoming bullets clearly. On the PSP’s 480x272 pixel screen, especially during the helicopter boss in MS2 or the space mission in MS3, bullets are nearly invisible. Using infinite continues is less about "cheating" and more about "accessibility." No surprise
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. Part 5: Are Cheats Ruining the Experience
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."
