my bad, i had received this information from Simon Howard directly
in one of my many conversations with him, and i must have heard
incorrectly. i revisited the opl(4) issue (and lack thereof) with
him and realized my error; it doesn't use any kernel drivers, the
game itself has the option of accessing opl hardware directly
via ioport access. hence requiring root access. ignore hardware
opl(4) things. the software opl emulator it provides by default
anyhow is quite authentic sounding.
