Ι Have Manli Geforce 2 MX 400 and I don't use any fixes except the one I mentioned earlier.
To install the fix, unzip the following to each corresponding places:
ldr_XCOM1.exe where ufo.exe is
ldr_XCOM2.exe where tftd.exe is.
More on the afternoon, I shall write the full paths.
BTW, I'd like to thank the creator of this patch, just to be correct. It's F0dder, thanks a lot!!!
