-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
