I have an indy2 sound.dat file that has been modified. A friend of mine
cut out that goofy engine sound and pasted an engine noise from gp2 in its
place, every thing else is the same, and I think it sounds much better then
the original. If any body would like to try it ask and I will send you a
copy. It is 2.63 MB in its uncompressed form.
