SPUREADY

Description

Pops one value (a sound-effect index) and kicks off an asynchronous load/prepare of that sound resource, resetting the async progress trackers to 0. Execution yields (returns 3) so the load runs in the background; SPUSYNC later waits for it to finish. On the original PSX this streamed the sound from disc (hence the drive noise).

PC handler: SCRIPT_SPUREADY.
