if the time does not matter for you, i can write a pretty clean code in the next weeks (not longer than a month), as i'm implementing a resaving feature atm for my editor. Though at the moment i'm working on the wmp files, and not on mdl files ==> Will need ~2 weeks to start that. If you need it earlier, a small payment would be nice - otherwise without a timeframe - i'll release it open source - but again please don't held your breath - just remember me of this topic in ~2 weeks
