The Settlers II has strong Amiga roots and this is clearly visible in the file formats the game uses. The clearest example of this are the LBM files that are Amiga’s IFF picture files, although not in the Amiga’s native format but instead in the Deluxe Paint for DOS format.
What makes things easy for us is that the files are not encrypted in any way, which makes it far easier to reverse engineer the information contained in the files. However this is still a lot of work and this work is not yet complete. A better understanding of the file formats also gives a better image on how the original game works, thus making projects such as RttR a bit easier to develop as well as provide the most important base of information for modding purposes.
