-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)
-ADPCM DMA speed now matches what krikzz's test rom expects
-Implemented some delays in CD-ROM interface that mostly match the test rom
-Implemented delay when software fails to read an entire sectore before the next one is ready (improves audio sync in Sherlock Holmes movies)
-Re-fixed issues with Ys IV that were apparently caused by the read command not properly updating the SCSI signals after the drive starts seeking to the requested sector
-Fixed some ADPCM playback flags/timing issues based on okitest test rom (playing/busy flag gets turned off slightly delayed vs end reached flag, etc.)
-Implemented delay for $1805 writes, based on test rom
-ADPCM edge cases work better (reset, length latching, dma, etc.)
-BRAM unlocking/locking fixes
-Read ToC command returns the correct amount of data
-SCSI data port returns the drive's reply whenever a reply is being read, regardless of the value written to the port through $1801
-Implemented/fixed audio sample read behavior (latching, L/R toggle)
-Fixed missing (unused) readable/writable bits in some registes
All of these fixes are based on the test results from krikzz's test rom here: https://github.com/krikzz/turbo-ed-pro-pub/tree/main/tcd-verificator
