Switching to a library cuts the total download bandwidth requirements roughly in half.
Because CHD is a high-efficiency format originally created for archiving arcade hard drives, it excels at slimming down file sizes while retaining all game data.
To understand why CHD reigns supreme, we must look at how it compares to its predecessors in terms of storage efficiency and data integrity.
Historically, CHD was only used for systems like the PlayStation 1, Sega Saturn, and Dreamcast. However, the PSP emulation landscape has fully embraced the format. The premier PSP emulator, , features native support for CHD files. Popular emulation front-ends and operating systems like RetroArch, Batocera, EmuELEC, and JelOS read PSP CHDs natively without requiring any annoying workarounds or plugin installations. How to Handle CHD Files (Get chdman from MAME tools
CHD, which stands for "Compressed Hunks of Data," is a file format originally developed by the MAME (Multiple Arcade Machine Emulator) project to compress the hard drive images of arcade games. Since then, its use has been expanded to cover many disc-based systems, including the PSP. At its core, a PSP CHD file is a compressed version of a PSP ISO (the raw, uncompressed disc image). It uses like LZMA and Zstandard, which can significantly shrink file sizes without losing a single bit of game data.
