"Compress game" in the game screen's ... menu, for ISO, CSO, CHD and PSN EBOOT.PBP games. It opens a list of the CSO presets (and Extract to ISO for anything that's not an ISO already): - Best: libdeflate level 12, 64K blocks - PSP Compatible: zlib level 9, 2K blocks, readable by custom firmware These match maxcso's presets, and the CSOs come out byte-identical to its. The writer, Core/FileSystems/CSOCompress, reads the input through PPSSPP's own block devices, so recompressing is a single pass with no temporary file. The original is deleted when done, unless "Keep the original file" is checked (off by default). When the new name is taken, by a kept original or another file, a number is added to it. The work runs on a thread using every core, with a progress bar and time left at the bottom of the game screen. It keeps going when the screen is left, and the ... menu offers Cancel meanwhile. On the game list the game's icon is covered by "Compressing...", and clicking it opens the game screen instead of playing. When done, recents follow the new file and the game screen and lists refresh.
