For decades, arcade preservation was a battle against physical decay. Enthusiasts dumped ROM chips from aging PCBs to save games from the scrap heap. The Taito Type X changed this dynamic entirely. Because the system ran on standard PC architecture (Intel Celeron CPUs, standard RAM, and hard drives rather than proprietary silicone), the "ROMs" were simply folders of data stored on a commodity HDD.

Unlike older systems (like the NES) where a "ROM" is a single file dumped from a cartridge, Taito Type X games are stored on standard Hard Disk Drives (HDDs) The Security:
Developers could choose different specs (like different CPUs or ATI Radeon graphics cards) to fit their game's needs. Ease of Development:
