Rocknroms could you check again the offset of your Ecco the Dolphin disc (http://redump.org/disc/4104/)?

Converting this image from TOSEC I get matching result with offset +2, not 0.

I don't have the cd anymore, but I can confirm you that offset is 0 by px_d8 logs I have.
By the way I found out that many TOSEC dumps have even wrong offsets (or at least there are more than one master).

(((7 * 16) + 8) / 4) - 30 = 0
