|

*
|
||||
* The samples were taken from Michael Strutt's (mstrutt@pixie.co.za)
|
||||
* excellent space invader emulator and converted to signed samples so
|
||||
* they would work under SEAL. The port info was also gleaned from
|
||||
* his emulator. These sounds should also work on all the invader games.
