No.22951 smf Developer 15 days ago	The game is now playable through a combination of a (guessed) interrupt disable in the CPLD, clearing interrupts after reading a sector and there is more data ready (which the ATA-1 says some drives will do) & a timing change in the SPU DMA handling. Further investigation is required, when hardware becomes available.
