Taito Type X Rom Set -

Because the Type X systems ran on standard Windows XP, the games were not burned onto ROM chips like old arcade boards. Instead, they were executable files (.exe), DLLs, and assets stored on encrypted hard drives. A Taito Type X ROM set is a misnomer—it’s actually a collection of game data dumps, decryption keys, and loader programs that trick the game into running on a standard PC.

Because the Type X is a PC, it does not emulate in the traditional sense of "emulating a CPU." It runs code natively on modern PCs.

The "Loader" Era Before MAME fully supported Type X, the primary method of playing these games was via "Loaders." A "Type X ROM set" was typically a folder of game files paired with a generic "Loader" application (such as Typex_loader.exe).

MAME Integration Modern versions of MAME (MAME 0.2xx and later) have begun integrating Taito Type X support. However, the MAME implementation requires specific, unmodified dumps of the hard drives and BIOS. This creates a split in the community:

| Game | Year | Notes | |------|------|-------| | Battle Gear 4 | 2005 | Racing, requires JVS I/O | | Homura | 2005 | Vertical shmup | | Raiden III | 2005 | Works well with loaders | | Shikigami no Shiro III | 2005 | Horror shmup | | Spica Adventure | 2005 | Platformer | | Battle Fantasia | 2007 | 2D fighter | | BlazBlue: Calamity Trigger | 2008 | Runs on Type X2 | | King of Fighters XII | 2009 | Type X2 | | Street Fighter IV | 2008 | Type X2 (original arcade version) | taito type x rom set

You do not “emulate” a Taito Type X in the traditional sense. Because the hardware is a PC, you are essentially repurposing your modern Windows PC to act as the arcade motherboard. This is done via a loader.

The most famous is the Taito Type X Loader (aka JVS Loader or Game Loader All RH). These are small utility programs that:

The Taito Type X ROM set is a miracle of reverse engineering and a challenge to copyright law. For the dedicated enthusiast, it offers the chance to play a golden era of arcade games—from the mainstream Street Fighter IV to obscure shmups—at home, perfectly preserved. For the hobbyist, it’s a weekend project of editing config files and troubleshooting DirectX errors.

But always remember: These ROM sets exist because passionate people cracked encryption, documented hardware, and shared files against corporate wishes. Whether you view them as heroes or pirates, they have ensured that when every Taito Type X motherboard has turned to e-waste, the games will still run. Because the Type X systems ran on standard

If you choose to explore the world of Taito Type X emulation, do so with respect for the developers, support official releases when possible, and keep the spirit of the arcade alive—not just the ROMs, but the joy of the games themselves.

Executive Summary The term "Taito Type X ROM Set" refers to the collection of arcade game data files (commonly referred to as ROMs) required to play games running on Taito’s Type X arcade hardware. Unlike traditional arcade boards that used proprietary custom chips, the Taito Type X (and its successor, Type X2) utilized standard PC hardware architecture (x86 CPU, DDR RAM, ATI Graphics). This architecture fundamentally changed how the "ROM set" is structured compared to older systems like MAME (Multiple Arcade Machine Emulator).
