Terramex:
I can see the beginning of the sectors (of the full image) using Isobuster:
Code:
LBA , File Name , Size (Bytes)
0000277 , \LASERLOK.IN , 20,480,000
0259145 , \Laserlok.o10 , 100,000,000
0307974 , \Laserlok.o11 , 20,000,000
0317740 , \Laserlok.o12 , 20,000,000
0327506 , \Laserlok.o13 , 5,000,000
But I don't know how to calculate the end of sectors and so set the y variable for each of them in your profile for BW.
