This paper provides a technical examination of "PSP ISO Compressor" utilities, software tools designed to reduce the file size of PlayStation Portable (PSP) game disc images (ISOs). As PSP games were distributed on Universal Media Discs (UMD) with capacities up to 1.8 GB, storage optimization became a critical requirement for users utilizing Memory Stick PRO Duo cards, which historically offered limited capacity and high cost. This paper explores the mechanisms of the CSO (CISO) and DAX compression formats, analyzing the trade-offs between compression ratios, decompression overhead, and gameplay performance on embedded MIPS architecture. Furthermore, it discusses the role of these tools in digital preservation and the shifting paradigm of storage constraints in modern retro-gaming contexts. psp iso compressor
