I occasionally run Fritz 8 on CEntOS 5 under crossover-pro-7.1.0-1,
and it mostly works. Crossover 6 was similar.
I have never gotten the HIARCS engine to install in
the interface and work, there is some kind of
copy protection that fails, though the same package
worked for me under WinME.
There are some interface glitches and clock problems,
but I don't remember anything major.
