All games.
I included game files which have zlib streams in arc.groups ($Deflate for pzlib3, $zStream for ztool), configure MASK in config0.txt, then choose MASK in UltraARC.
pzlib ztool doesn't work anymore for me (on the point when ztool starts, it copies files without any precompressing, pzlib3 the ratio is always at 100%, so input/output is always the same, doesn't matter which settings i use).
Maybe some win update or other software. I don't know
