The primary appeal of high compression is purely practical. Original PS1 games, stored in standard formats like BIN/CUE or ISO, are large by retro standards, often ranging from 400 to 700 MB per disc. For a multi-disc RPG like Final Fantasy VIII , a full library could consume hundreds of gigabytes. Highly compressed formats, such as CHD (Compressed Hunks of Data) or PBP (PSP format), leverage advanced algorithms to shrink these files by 30-50% without altering the core gameplay data. This allows collectors to store entire libraries on a single microSD card for a portable device like the Anbernic or Retroid Pocket. For users with limited bandwidth or metered internet connections, a compressed file downloads faster and saves money.
