    "Numérisation_20190430 (48).png" is interesting, according to it DCs had number of component revisions:
    SH4: MP9, MP10, MP11
    HOLLY: V2.40, V2.41, V2.42, V2.52, V2.53
    AICA: 2bank or 2/4bank
    Flash ROM: 1Mbit or 8Mbit

    wondering what is the chip differences ? I think its the 1st time I've heard of HOLLY v2.5X, "4-bank AICA" sounds interesting too.
