There's a tool called "Compatibility Administrator" that can be used to read
compatibility databases. It turns out that there's an entry for Indiana Jones
and the Emperors Tomb. The game uses compatibility fix called
IgnoreFloatingPointRoundingControl, it contains following description:

Before floating point sse2 support in C runtime library, the rounding control
request was being ignored which would use round to nearest by default. This
shim ignores the rounding control request to support applications relying on
old behavior.

According to the tool, Indiana Jones and the Emperors Tomb is the only
application that uses this shim.
