Good job with SATA adapter. You are lucky as I and hoped ))
I also order it for yourself But I see, the speed in DMA noticeable worse than on Native IDE (up to 4 MB/s less)... And PIO mode too, but not much (there may be a delay in requests).
Your adapter based on Marvell 88SA8052, maybe another adapters on this chip and slave support can be success.

BTW, for this game (and part 2) you can use DMA transfer, just setup checkbox for it on settings page of this application.
It's can be work even better. Yeah, really better
Very sorry that I have not been able to do DMA support for all games, I still do not know the reason for not works it in most games, so while I added this option.
