-IRQ/SCSI status should happen after seek is done when a play command is sent (fixes audio sync in Brandish intro cutscene) -Fixed seek delay not being applied correctly when swapping from audio playback to data loading and tweaked seek delays to make them a bit slower (fixes Brandish audio glitch during introduction) -Fixed regression that causes the "transfer ready" irq flag to not be reset when a sector was done reading (this broke the intro sequence in "It came from the desert") -Improved behavior when a load operation is cancelled (to match the expected results of both scsitest and verificator tests)
