Hello icexuck,
But about integrating... I'm not so much into this topic, but I think it will be a no-go to include graphics files that are very much based on the original MAX graphics files into the maxr package. We have the free graphics set, that is created completely from scratch. The res-installer is only a tool, that gives owners of the original MAX the possibility to use the original graphics. But we don't deliver the original graphics. If you now changed the original pcx to enhanced png files, we probably won't be able to include these in any package downloadable from this website/project.

But what about this (wild) idea: You only make a layer on top of the original graphics, that probably will use transparency heavily. I think we could distribute these top-layer-png-files. For the free graphics set they won't be of any use, but for the players that use the original graphics, it could be a great enhancement (that could be turned on in the preferences for example).

What do you think? And beko, what do you think?
