Double Dragon II (OCL crack decruncher)

Could anyone please tell me what the decruncher is for the 2nd file
in the startup-sequence ("dragon") from the following crack :-

Double Dragon II - The Revenge v3.84 (1989)(Virgin)[cr OCL][t +2 OCL]

..It doesn't appear to be recognised in xfddecrunch.

Thanks.

It will either be a variant of Bytekiller disguised or it will be Weetibix's own packer.

Can still be easily depacked if you need help, and then repacked with something else.

Doesn't look like bytekiller, but you can put breakpoint at $10110 (or $7f000) and dump uncompressed data from $1C200-$3057c (entry point is $30000) - in winuae:
S c:/temp/dragon.bin $1C200 $3057c-$1C200
.

Thanks Paraj. That's a bit beyond the scope of what I want but I appreciate the reply!

It's a modified Defjam packer binary.
