hehe
would be nice to see that file
(I still cannot download though )

anyway, I think this "decrypting" and "dumping" approach won't lead you anywhere.

there must be a table, based on which the morpher engine selects instruction(s) to replace the current one with, so the proper technique involves writing a 100% tracer routine and access to that table.
