While in Imp1 resources (graphics, texts and etc) are packed in .gob files which are opened by any archiver software, in Imp2 ther are packed in .rsrc format that is not opened so easily.

There are GitHub page with custom Imp2 unpacker but it seems that the main file is no more available.

Were any of Imp2 fans lucky to have had this tool before it was gone from the Internet? Or maybe somebody knows other tools to unpack Imp2 resources?

Answering my own question: Game Extractor software is the perfect tool for Imp2 resources (and for more than 4000 other PC games). Google it, check it, try it.
