This ROM image is compatible with Kickstart 2.04 (and later). It is a modification of 30B54232 (A570 CD peripheral ROM), adapted for use on CDTV systems by Jeff Weeks for Cloanto. The difference between this 2.30 ROM version and the A570 CD peripheral ROM version is that the A570 version expects DF0: to be present, whereas the CDTV ROMs verifies whether DF0: exists or not.
