Disk structure
This is a modified DOS 3.3 single-sided floppy disk.
As usual with Sunburst titles, they modify markers, they are set based on the track number. They also play with the interleave. As a conclusion, they modify the DOS 3.3 RWTS a lot. Today, I'll take the lazy route and replace the entire DOS 3.3 on disk and put a standard one.
The + is that it will run and run with a standard DOS.
The - is that the reboot routine on T0/S0 is lost.
For those who prefer to update the original RWTS, I've uploaded the standardized DOS 3.3 disk.
The markers are as follows:
- D5AAxx 970000, xx depends on the track number
- D5AAyy D30000, yy depends on the track number
The routine is at $BA69
