HowlingDog v2.0.2

HowlingDog v2.0.2.

A standalone Neo Geo emulator for Android (AES / MVS / Neo Geo CD / Neo Geo CDZ) around the Geolith libretro core.

Bug fixes

• Search field is now themed with the app (maroon field, gold border and text, Neo Geo system font) and the full text is visible — no more clipped search text.
• The Arcade Manager button is now a normal button alongside Add game, Add folder, and Settings — the tall vertical strip on the right of the library is gone.
• The collection entry point is back: per-game settings has a Collection row showing the current collection (or None) that opens the picker, so a game with no collection can get one assigned.

HowlingDog v2.0.1

HowlingDog v2.0.1.

A standalone Neo Geo emulator for Android (AES / MVS / Neo Geo CD / Neo Geo CDZ) around the Geolith libretro core.

Bug fixes

• CRT shader row in Settings now shows the effective state: when Edge smoothing is on, it reads "Off" with a note, instead of reading "On" while the CRT was actually off.
• Arcade Manager heatmap: the centre cell now labels the direction total as "TOTAL" instead of showing a bare number.
• Arcade Manager now lists games by the library display name, and keeps games with stats that left the library, by file stem.
• System files card: the status line reads just "4 of 4 ready" instead of repeating "System files: 4 of 4 ready".
• Game tiles no longer show an empty "COLLECTION: —" line when no collection is assigned.
• RetroAchievements: the Username and Password fields are hidden while logged in; "Log in again" reveals them.
• Library Search field is now the same height as the Add game, Add folder, and Settings buttons.

HowlingDog v2.0.0

HowlingDog v2.0.0.

A standalone Neo Geo emulator for Android (AES / MVS / Neo Geo CD / Neo Geo CDZ) around the Geolith libretro core.

New features

• Playtime tracking: total time played per game, shown on the game's detail.
• Per-game saved control positions: adjust the overlay while a game is loaded and the app remembers those positions for that game only.
• Memory card manager: a screen showing what is on the virtual memory card, with sizes, and deletion of stale saves.
• On-screen input display: a strip showing recent inputs as they happen, toggleable in Settings and off by default.
• Dynamic haptic arcade-stick feedback: a microswitch click when the stick crosses an actuation threshold, and a heavier vibration for the Coin button.
• Arcade Manager: per-game input heatmaps and a virtual revenue tracker (coins dropped x 25 cents) alongside total playtime.
• Dither-aware edge-smoothing shader: a new display option (off by default, an alternative to the CRT shader) that smooths sprite outlines while preserving Neo Geo checkerboard dither, with directional interpolation, corner preservation, temporal stability, and color-aware blending, plus a sharp-CRT combined mode.

HowlingDog v1.5.1

HowlingDog v1.5.1.

A standalone Neo Geo emulator for Android (AES / MVS / Neo Geo CD / Neo Geo CDZ) around the Geolith libretro core.

Bug fixes

• Achievements that read the cart backup RAM (high scores and settings stored in the MVS backup RAM) now work: the core exposes its 64 KB NVRAM as SAVE_RAM, and the RA wrapper maps it at 0x10000-0x1FFFF, right after the work RAM. Before this fix those achievements read as unmapped and RetroAchievements disabled them.

HowlingDog v1.5.0

HowlingDog v1.5.0.

A standalone Neo Geo emulator for Android (AES / MVS / Neo Geo CD / Neo Geo CDZ) around the Geolith libretro core.

New features

• Cheats: enter per-game codes (pause menu > CHEATS) and they write to the game's work RAM after every frame. Codes are typed in (8 hex digits) and saved per game; there is no bundled cheat database.
• Two-player multiplayer: connect a second gamepad and it controls player 2. The first gamepad you press is player 1, the second is player 2.
• Fast-forward and slow motion: hold the on-screen FF or SLOW button, or hold the gamepad stick clicks (L3 fast-forward, R3 slow motion), at the speeds set in Settings.

Improvements

• Save states now show a thumbnail of where the game was, and the game saves itself to slot 1 when you quit, so you can pick up where you left off.
• The library gains search, sorting (name, year, recently played, system), collections to group games, and per-game metadata (year, maker, genre, players) on each tile.

Bug fixes

• Various bug fixes and stability improvements.

A standalone Neo Geo emulator for Android (AES / MVS / Neo Geo CD / Neo Geo CDZ) around the Geolith libretro core.

New features

• RetroAchievements leaderboards and rich presence: see the boards for the game you are playing, your live attempt, and the top entries, and your profile shows what you are playing.
• RetroAchievements now works for .chd discs: a .chd CD game identifies and loads its achievements exactly like a .cue/.bin disc.

A standalone Neo Geo emulator for Android (AES / MVS / Neo Geo CD / Neo Geo CDZ) around the Geolith libretro core.

New features

• RetroAchievements now signs in with your username and password, like other emulators. The API-key login is gone: the password is used once to log in and is never stored on the device — the app keeps the session token the server returns, so the next launch signs in without it.
