first part of the boot is a bsr to trainer, and then a bsr to Nemesis boot intro.

if boot is loaded @ 50000 :
at 50380, load trainer (sector 11, len 7) at 40000. Jump at 40024 to start trainer. and after a bsr 50040 (nemesis)

patch the exe by changing the first bsr :
bsr 50380 => bra 50040
and nop last line of intro before movem (a7)+,d0-d7/a0-a6 :
"move.l #$100,$96(a5)" (@ 5012a)

Broke up my teeth on the Nemesis bootblock intro for Cisco Heat. Rather tricky, this one, I guess, as it first reads then launches the trainer in the middle of the disk, and launches the bootro afterwards .. . Tried to extract it without any success at all.
Help would be greatly appreciated on this one :)

If you send me the disk or a link to it, I'll send you back an annotated source (of the loader, not the intro :)
