When I arrived at work this morning I checked The Zone on EAB and found
this game uploaded there. Had a quick look and it was interesting enough
to create a patch. The disk format is standard Amiga DOS but each block
is encrypted, the patches for the DoIO and other OS calls are installed
in the bootblock in a quite nice TVD-like fashion. However, as interesting
as the disk format is as simple it was to defeat as it's clear that the
data is loaded using standard Amiga-OS system calls.
Creating the RawDIC imager was quickly done and patching the game didn't
take that long either, there were quite a few bugs to correct though!
Worst one is the copperlist trashing, coder stored the pointer to replayer
binary but only allocated a word for it which in turn meant the first word
of the copperlist was destroyed. Talk about lame code... This has been
fixed of course!
There are some strange bugs in the replayer, after spending quite some hours
to find the reason without any success I decided to release the patch as is!
The sound problems even occur on a standard 68000 Amiga so something must
be seriously broken. Should I find the reason I'll update the patch.
A funny thing concerning the protection was the actual protection track check,
it was performed in a fake "stack" command, very lame indeed (something similar
was done in the TV Sports Football "protection").
Anyway, enjoy the game from HD, it's not exactly great in my opinion which is
why I didn't bother to add any trainers at all.
Thanks to Nujack for the disk image!
