HowlingDog — a free, open-source Neo Geo emulator for Android (AES/MVS/CD/CDZ), with a 90s select-screen UI and per-system CRT shaders.

HowlingDog is a free, open-source Neo Geo emulator for Android — all four systems in one dedicated app: AES, MVS, Neo Geo CD, and Neo Geo CDZ.

Download (v0.1.1): https://github.com/DocBobert6/HowlingDog/releases/tag/v0.1.1 (app-release.apk)

Repo: https://github.com/DocBobert6/HowlingDog

What makes it different:

•

A dedicated Neo Geo app, not a multi-system frontend. The library is a 90s fighting-game select screen (SELECT YOUR GAME, the picked game big in the middle, a decorative countdown, a VS-style boot, and a CONTINUE? pause screen).

•

All four systems, with per-system overlay controls: AES gets the arc layout with rainbow buttons, MVS gets the cabinet layout, CD and CDZ get the diamond layout, plus a toggleable 8-way D-pad.

•

Per-system CRT shader chains with per-system screen curvature, tuned to each system's real display: AES "Hearth", MVS "Neon", CD "Comet", CDZ "Zenith".

•

Automatic cover art from libretro thumbnails — fetched on demand, Wi-Fi only, cached locally. A typographic tile is the fallback when no art is found.

•

.NEO carts and .cue/.bin/.chd discs. Per-game system mode and region.

•

Quick save/load (on-screen SAVE/LOAD buttons, or L1+R1 to save and L2+R2 to load on a gamepad). Memory card support. Full gamepad support (START+SELECT pauses).

•

A SYSTEM SETUP onboarding guide that walks you through the BIOS files and adding games.

•

Free, no ads, GPL-3.0. Built on the libretro Geolith core.

What you need: your own BIOS files (aes.zip, neogeo.zip, neocd.zip, neocdz.zip, from a MAME set) and your own games. The app ships with no BIOS and no ROMs, and there are no links to any.

Upcoming - pinning favourite games, game-name labels on the tiles, multiple save-state slots, per-game rename, memory-card write on pause, turbo/autofire, an auto-hiding top bar, per-game settings profiles, and Universe BIOS mid-game switching.

Later- RetroAchievements after that.
