We used it in our games since Ultimate Spiderman. I've got assembly version working on the PS2 IOP chip (33Mhz, the chip used to run PS1 games, otherwise I/O and sound for PS2). I've got 5mb/s decompressed data speed, so that was speeding our disk access. I had to tweak just a little bit the source code and make sure unaligned writes (4 bytes) were used and that made it x2 or x3 faster.
