The 'Sonic' is the speed of sound, not a hedgehog — and the cockpit beside you might hold a dolphin.
Video System named their 1994 vertical shooter for flight at the speed of sound, years before anyone confused it with Sega's mascot. What you actually find here is gentler and stranger than any war: a roster of pilots from around the world, including a pop singer in a fancy dress (Mao Mao), a baby in diapers flying for the RAF (Bobby), and Spanky, who introduces himself as the world's first dolphin pilot. Because any pair can fly together and the game tracks where they end up, a single sky holds dozens of small farewells. You come for a tight Neo Geo shooter; you stay because someone thought a dolphin deserved a fighter jet.
About this game
Aero Fighters 2 is a shoot 'em up for the Neo Geo (1994), from Video System. Part of Enjoy Game Japan Museum's record of Japanese originals.
Tricks & Tales
The title 'Sonic Wings' refers to flying at the speed of sound and has no connection to Sega's Sonic the Hedgehog; it was developed by Video System and runs on SNK's Neo Geo hardware. Spanky (named Whity in the Japanese version) is a dolphin who pilots a fighter jet, and even announces himself as the world's first dolphin pilot — sharing a roster with Bobby, a diaper-wearing baby flying for the RAF. Unlike the first game's fixed national rivalries, any two pilots can be paired freely here, and the game gives the series' largest set of endings depending on who you fly with.
Collector's Guide
Region & Compatibility
The Neo Geo AES has regional variants (Japan and international / English) but is notably more region-tolerant than most consoles of its era. Many AES cartridges contain both Japanese and English text and will display the appropriate language based on a DIP switch setting on the console. The Japanese and international versions of most games are functionally identical; some late-era games have minor content differences. The MVS system also uses DIP switches for region and language configuration, and this carries over to the AES architecture. Collectors who prefer the Japanese text of the original releases should note that importing a Japanese AES requires no voltage conversion for European users but does require a step-down converter for North American 120V outlets.
Maintenance Tips
The Neo Geo AES uses a 3.6V lithium battery to retain game saves and settings. After thirty-plus years, virtually all unserviced AES units have a dead or dying save battery. Symptoms are lost high scores, reset date/time, and in rare cases settings corruption. The battery is a standard CR2032 or similar coin cell, accessible by removing the rear panel — replacement is a simple swap rather than soldering on most units. The edge connector that receives cartridges can develop oxidation over thirty years; cleaning the cartridge PCB contacts and the console's cartridge slot with 90%+ isopropyl alcohol on a cotton swab restores reliable contact. The cartridge PCB contacts are gold-plated on most AES cartridges and resist oxidation well, but the connector can accumulate dust and debris that causes intermittent recognition failures before genuine oxidation sets in.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Aero Fighters 2 copies regularly.
Is this related to Sega's Sonic the Hedgehog?
No. It's a Video System vertical shooter on the Neo Geo; 'Sonic' here means the speed of sound. Internationally it was released as Aero Fighters 2, so listings under either name are the same game.
Are the Japanese (Sonic Wings 2) and overseas (Aero Fighters 2) versions the same game?
Yes — same 1994 title, with some character names changed for export (for example the dolphin Whity became Spanky). Check whether a cart is the AES home version, the Neo Geo CD disc, or an MVS arcade board, since they aren't interchangeable.
