PS2 Compression
I had all .gz compressed. Most recommend chd now.
gz
I extracted to iso using 7zip.
PCXS2 can load .gz files but creates the large pindex.tmp files making a mess.
The retroarch ps2 core LRPS2 doen''t work with .gz. It does work with iso. It LRPS2 does work with .chd but the .chd must be default compressed Compression: lzma (LZMA), zlib (Deflate), huff (Huffman), flac (FLAC) not zstd to work.
736 GB .gz
1.16 TB in .iso
chd
chdman
- chdman documention
- launchbox forums
- retro game corps
- If source is ISO use createdvd command
- If source is cue or cd iso use createcd
chdman createdvd -input "source.iso" -output "target.chd" -compression zstd -force
zstd
So it seems zstd doesn't work with LRPS2.
So we will stick with default of
Compression: lzma (LZMA), zlib (Deflate), huff (Huffman), flac (FLAC)
After conversion to mostly chd
- 736 GB .gz
- 1.16 TB in .iso
- 706 GB in mostly .chd
I left 0Best, and Horror in iso. Also one simple 200 series refused to concert. v106 The Block Kuzushi Quest Dragon Kingdom.
Everything else is .chd
