it doesn't seem to be working in our EmuTOS :-)

my documentation clearly suggests that the v_dspcur() is the right way -
if it worked.

not sure if EmuTOS implementation is the right one to learn from. And
XaAES does not implement it at all. Don't know about other AESes with
open source code.

Thinking about N.AES - couldn't that one simply call the ROM TOS tplay
instead of implementing its own solution (that doesn't seem to be
possible, anyway)?
