I understand the technical appeal of this effort, but wouldn't it be easier to try to obtain the original source code? Or has that been lost and all that's left is a blob?
Fundamentally, decompilation is not solving a technical problem most of the time (because the source already exists somewhere) but a social one (that the owner doesn't want to release it).
