I've made minor updates to pretty much everything including pads, wallitems, generators, teleporters, doors, texts and mirror characters. However the major change (and the main reason why I dug the source code out in the first place!) is that you can now use DMute to export DM /. CSB dungeons into the <a href="http://www.ragingmole.com/RTC">Return To Chaos</a> (RTC) format.
One small caveat. The implementation of various items (especially mirror characters and triggers) is very different between DM / CSB and RTC (for example, DM / CSB targets every item on a given tile co-ordinate, where as RTC allows you to select individually which items to target, possibly on multiple different tiles) and so the conversion process isn't perfect. I've tried to get DMute to handle most of the frequent differences but it still requires a manual step to go through and make sure everything works as expected. Having said that, it gets over 99% of the original DM and CSB dungeons right first time, so it's not too bad

If you have any comments, spot a bug (surely not!) or have some suggestions for further improvements, please let me know. In the mean time, have fun!
