I've uploaded Sakura Taisen 1 & 2 DSF rips to my page along with a current version of dsfmake.

Does Toy Fighter use the Manatee driver or something else?

Virtua Fighter 3TB uses a non-manatee driver, and I haven't figured out how it works yet. Here's a pack of the driver w/ 2 sound files: http://h1.ripway.com/kingshriek/vf3tb.zip

It appears that 0x60-0x80 is used for SH4/ARM communication and that sound files are mapped at address 0x10000 from a look at the driver code.
