I need to explain the process step by step. Maybe start with checking the game format. If it's an ISO, convert it to CSO. If it's already a CSO, adjust the compression ratio. Also, tools like CSO Manager or PSP ISO Compressor could be mentioned. It's important to mention that higher compression might affect load times or performance, so balancing quality and size is key.
