Zarchive for CHD as compression for data

[Papermanzero]

The idea is to use Zarchive from excap as data compression for the next version of CHD.

Zarchive provides currently the best way to compress data especially for modern disc based games (wiiU, xbox, 360, ps3)

moreover zarchive is a lossless format which is perfect for archiving original discs.

Zarchive would provide a benefit compared to the current lzma or zlib algorithms.

CHDMAN already supports Zstd compression, it was added in the 0.262 release.

But is zstd not different compared to zarchive?
Just asking because several emulator projects discuss about zarchive vs chd. But i think if chd supports the compression from zarchive it would solve everything. Personally i think chd is the future for all emulating projects.

if chd is already supporting it would be an awesome news for many projects

Edit: thanks for the support! Yes I read it is the same. Thanks a lot!

Zstd is what Zarchive uses, yes.
