Metal Slug Anthology for PSP collects classic Metal Slug arcade/Neo Geo titles (Metal Slug 1–6, Metal Slug X, Metal Slug 3). The PSP release doesn’t include built-in “traditional” cheat code menus like some emulated ports, but you can still access useful in-game shortcuts, exploit mechanics, and use external methods (savedata editors, Action Replay/cheat device formats, or emulator-specific cheats) to modify lives, credits, weapons, or enable special behaviors.

To quickly earn tokens for the gallery, play through Metal Slug 3 or 5 on Hard. Just after defeating the final boss, save the game immediately. Watch the credits, then return to the main menu to receive 5 tokens. Reload your save to repeat the ending and farm tokens indefinitely. CWCheat & PPSSPP Codes

Reload that save file to watch the ending again and receive another 5 tokens repeatedly. CWCheat Codes (For Emulators like PPSSPP)
