ripping some data from upx packed file

Hi,

I`ve got upx packed file that contains some graphic and music module. It`s a keygenerator from vengenace group. I used procdump32 to dump keygen process from memory and now file is 10 times bigger than original and still works fine so I suppose that file is now unpacked and descrambled (maybe I`m wrong, I don`t know). Then I used DOS multi ripper 3.0 and I found these bitmaps inside. It also found mxm file (probably it`s a gus music module format) but file is to big and has many unwanted informations about dll calls inside so I`m sure that file is incorrect. So my question is...would it be possible to ripp manualy music played by keygen ?? I know that some people did such thing so can you give my some clues ? I`d be gratefull for every suggestion

Best regards
Peter
