ALPHA MISSION II ACA NEOGEO APK + MOD vv1.0 (Unlimited Credits, All Modes Unlocked, Ads Disabled)

ALPHA MISSION II ACA NEOGEO Mod is a direct emulation of the 1991 SNK arcade shoot 'em up, part of Hamster Corporation's ACA NEOGEO series. It is a vertical scrolling shooter where players control the ASO II fighter, collecting and switching between eight different armor parts to adapt to enemy formations. This version targets retro gaming enthusiasts and preservationists seeking an authentic, unaltered arcade experience with modern conveniences like save states and display filters.

What This Mod Unlocks

• Unlimited Credits: The primary in-game currency for continuing play is set to an infinite value.
• All Game Modes Accessible: Arcade Mode, Caravan Mode, and Hi-Score Mode are fully unlocked from the start.
• No Advertisements: All interstitial or promotional content within the emulator wrapper is removed.

The mod functions by patching the game's memory values for credit count. This bypasses the standard arcade limitation of a finite number of continues, allowing for extended practice sessions or full completion runs without interruption.

To activate the unlimited credits, simply start a game in any mode. The credit counter will display a fixed, non-decreasing number. Inserting a continue by pressing the designated button will not reduce this count.

The APK requires Android 4.4 or higher and approximately 45 MB of free storage. Root access is not required. The mod is applied directly to the APK file.

Installation Steps

1. Download the modified ALPHA MISSION II ACA NEOGEO Mod APK file.
2. Enable "Install from Unknown Sources" in your Android device's security settings.
3. Navigate to the downloaded file using a file manager and tap to install.
4. Launch the game from your app drawer.

Known Edge Cases

The unlimited credits mod is local to the device and does not affect online leaderboards. Scores submitted to the ACA NEOGEO global ranking are not modified. Clearing the app's data or cache will reset all local high scores and save states, but the unlimited credits will remain functional upon a fresh start. On some devices with custom ROMs, the ACA NEOGEO emulator's virtual control overlay may require manual repositioning. The mod is confirmed for version 1.0 of the app; future official updates from SNK may break compatibility until the mod is updated.
