I bought one of Rom1's CPS-3 BlueSCSI boards. It's an absolutely fantastic bit of kit and a big quality of life improvement compared to using the original CD-ROM drive. Comms were excellent and the board was packaged well and sent quickly. He even helped me get it running properly on my Darksoft setup (I needed to swap the default ISO on the SD card to one that matched my specific BIOS). Can't recommend highly enough!
