That exactly is the problem with finding anything meaningful in it. You knew that, of course, because all disassembly somewhat looks like this. _071B:003E -įigure 1: The Disassembly looks like this.

Subsequent restructuring of the code in a more high-level style did not reveal any hidden secrets, at least not to me. I ported the assembly verbatim to C (think: uint16_t ax = 0x0 ), and I was done. One evening without consciously doing anything different than before, I "just knew" I was, finally, looking at the disassembly of the right function (Figure 1).

I don't even know what I did wrong over all that time. Over years I have revisited and left the problem again many times, Years with pauses of several months between shorts bursts of renewed interest, the latter often coinciding with updates in Krishty's "Extracting Ace Combat" Thread here. My moderate success was not due to some sudden spark of genius but due to more sleepless nights than I care to admit in which I banged my head at the disassembly. In the end this is not the tale of a great feat I would have hoped it would become. Long story short, I have managed to convert some of the assset files that come with "Sid Meier's Railroad Tycoon Deluxe" into a modern file format (png) and have a pretty good idea of what the other files are about.
