Hi :-)
In fact there IS differences between Amiga's ROMs.
You can not use A3000's roms in an A4000D since you will miss the right scsi.device (IDE_scsi.device in the A4000D and SCSI_scsi.device in an A3000(T), and a small file named A3000_bonus IS different from the A4000_bonus file in the 4000's Rom.
And some other small but important differences (memory space used, ect...).
The only Roms that are pretty identical are A500 and A2000 ones and are interchangeable.
Skick is really ageing now, better use Blizkick.
Conclusion : You have to have an A4000 ROM in your A4000, either Real or Softkicked for it to work :-D
Amigalement,
Jean-François.
