With Sony’s shift away from legacy consoles, the responsibility falls to fans. Projects like Redump (disc metadata), No-Intro (ROMs), and Internet Archive (limited legal collections) are fighting to keep Japanese PSX games alive. CHD is now the archival standard adopted by these groups because:
In Japan, there’s a growing “digital preservation movement” led by retro YouTubers like Kikujiro and Game Preservation Society. They advocate for CHD as the distribution format for their dumps of ultra-rare games like Tobal No. 2 (only 50,000 copies printed).
CHD comes with MAME. Extract MAME tools and run: Psx Chd Japan -
chdman createcd -i "game.cue" -o "game.chd"
For multi-disc games, keep each disc as a separate CHD, then create an .m3u playlist (e.g., Final_Fantasy_VII_International.m3u) listing all disc CHDs.
.chd files in one folder.Tool: chdman (part of MAME)
Command:
chdman createcd -i game.cue -o game.chd
For multi-track Japan discs (e.g., with redbook audio), CHD preserves layout.

If you’re building a “Psx Chd Japan” library, these titles are essential (and dramatically benefit from CHD compression): CHD comes with MAME
