exA-Arcadia is a PC-based arcade platform released in Japan on November 27, 2019, with an international release on January 2020. It's designed as an affordable modern cartridge-based conversion kit in an era of expensive dedicated machines and digital distribution systems (which force operators to "revenue share" titles and pay monthly fees for network infrastructure usage).
Designed for use as conversion kits for numerous types of JVS-compatible arcade cabinets, it supports numerous arcade configurations (including linked play and support for both 16:9 high-definition LCD 4K screens and 4:3 standard-definition CRT monitors) and swappable cartridges with support for four cartridge slots (which, similar to the Neo Geo MVS, allows players to choose from multiple games installed on the same machine).
While an internet connection is not needed, operators will be able to enable certain online-connected services, including support for smartphone companion apps and integrated Twitch streaming.
exA-Arcadia is compatible with a wide variety of development tools for game development including Unreal Engine, Unity, Game Maker Studio, Solar 2D, ClickTeam Fusion, OpenBOR, STG Builder, 2D Fighter Maker 2nd and Pixel Game Maker MV. The engines for 2D Fighter Maker 2nd and Pixel Game Maker MV have been exclusively licensed by the exA-Arcadia company from Kadokawa and upgraded for low input lag, scanlines and up to 4K resolution output.
Games developed for the system are a combination of 1st party/2nd party developments and third-party (but published by the exA-Arcadia company themselves) and are complete arcade remakes or arcade optimized, enhanced ports of games for existing home systems or PC with exclusive content not available to the home market. The exA-Arcadia company has at least 6 internal development teams codenamed exA-Arcadia TEAM EXA-AM1 to TEAM EXA-AM6 who have developed Dondonpachi True Death EXA Label / Dodonpachi Saidaioujou EXA Label and Gimmick! EXACT☆MIX.
The Japanese version of the system launched with one game, Aka & Blue Type-R (a remake of Aka to Blue), while the overseas version launched with the aforementioned remake along with The Kung Fu Vs Karate Champ, an enhanced version of Shaolin vs. Wutang: Eastern Heroes featuring optimized input lag, rebalanced game play and exclusive characters/stages.
