Bacause you just can't have Initial D without eurobeat, here's a batch that will convert the SPSD files into GENH ones that are playable by current public VGMStream.

Songs seem to loop, but I don't think the looppoints are determined in SPSD header, so they are unlooped. They might sound glitchy near the end.

I'll post updated batch if I manage to find them somehow (so keep the original SPSDs handy).
