Legal and ethical considerations

Patches themselves are typically non-commercial fan projects; however, distributing copyrighted game ISOs is illegal in most jurisdictions.
Legally safe approach: only apply the patch to a game image you legally own and create by dumping your own UMD.
Respect patch authors’ distribution rules; some provide only the translation files and patcher to avoid redistributing the game.

Play experience and limitations

Translation quality varies by patch—some are polished, others rough or incomplete.
Some elements (voice acting, certain assets) may remain untranslated.
Minor bugs or text overflow issues can persist due to engine limitations.
Multiplayer functionality may be limited or incompatible when using modified ISOs, especially on PSP networks or ad-hoc.

Fully Translated:

Main Menu & Options: All settings, save data, and configuration menus.
Weapon List & Descriptions: Every weapon’s name, ammo count, range, reload speed, and unique traits.
Mission Briefings & Objectives: Clear, concise directions before each battle.
In-Mission Subtitles: All radio chatter, squad orders, and commander speeches are subtitled in English.
Loadout & Shop Menus: You can now buy, sell, and equip gear intuitively.
End-of-Mission Reports: Rank, kills, damage taken, and new unlocks.

Not Translated (Due to Technical Limits):

Spoken Dialogue Audio: The original Japanese voice acting remains. This is actually a positive for purists who enjoy the authentic “Japanese B-movie” feel. No English dub exists.
Some Environmental Textures: Rare texture files like “START” on the ground or billboard text may still be in Japanese, but they don’t affect gameplay.
Multiplayer Menus: Ad-hoc multiplayer works, but some pre-game lobby text may be only partially patched. However, basic functions like “host,” “join,” and “ready” are clear.
