;Full dump to CHD Compression

* '''[[Ripping_games#Preservation_Priority_(Recommended_Workflow)|Archive-quality dump]]?'''

Before MAME v145, CHD was in version 4 and it bumped to version 5 from MAME v146 and further. The CHDv5 uses 7zip's LZMA compression on the game data and lossless FLAC compression for the audio data to optimize compression even further than using BIN+CUE+MP3/WAV data separation alone. CHDv5 is lossy until all the bugs are resolved.

* '''Gain:''' Immediate

* '''Can be reverted?''' Partially. Use extractcd (included with MAME), CHDroid.

* '''Playable on Hardware?''' No.

* '''Playable on Emulators?''' MAME, DuckStation, PCSX2, PPSSPP, DEmul, NO$PSX, Xemu, Xenia, RPCS3, Cxbx-Reloaded. Some [https://github.com/search?q=repo%3Alibretro%2Flibretro-core-info%20chd&type=code libretro cores] for other emulators are starting to add support.
