The primary driver behind the demand for games under 200MB was the hardware limitations of the early 2000s. Original PSP titles, such as Grand Theft Auto: Liberty City Stories or Final Fantasy Crisis Core , often ranged from 1GB to 1.8GB.

Furthermore, downloading files exceeding a gigabyte was a time-consuming endeavor on DSL or 3G connections. Highly compressed files, often shrunk using formats like .cso (Compressed ISO) or .dax, offered a solution. They allowed players to build libraries of classics without the need for expensive proprietary memory cards.
