Actually here and a while there's a thought to create RDTExplore2 I think there's already enough information about RE2 RDT's files to create a better tool than RDTExplore for RE1 is, but I can't seems to find enough motivation to start writing it and I don't want to start something that I may quit later on. So all I can tell right now is hopefully soon I'll eventually star writing it, can't say when exactly though.
Also are you aware of
THIS project?
