No Galaxy Angel Dating Sim Exists — No Cheats

No official Galaxy Angel dating sim exists. The franchise (anime/manga/visual novels) never received a standalone dating simulator release.

What Exists

• Galaxy Angel (2002, GBA): Strategy/RPG hybrid — not a dating sim
• Galaxy Angel: Moonlit Lovers / Eternal Lovers (PC): Visual novels with romance routes — Japanese only
• Fan projects: Ren'Py mods, fangames — no official cheats

If you're playing a specific fan game, name it. Otherwise, the premise is mistaken.
