Now I uploaded both images (DOS German version and Windows Ger/Eng version) on FTP. I didn't made replacing of .GER files, so both games on German now. Windows version can be easy "Translated" to English as
songbird described. DOS-version somewhat more tricky, as it doesn't install language files on HDD. If anyone need ENG, whole image need to be re-cooked.
But I can do it, uploading third, English CD, if it is needed.
---edit---
Wow. Site in mess, it seems.
