it's likely that these texture issues are specific to the game engine, and I doubt even having the original source code would allow us to fix them, although who knows.

It's not certain that the engine is to blame; psatkha mentioned somewhere that the graphics were downgraded in terms of capabilities so that the game would run even on the "calculators" of that time. If you compare the graphics in the alpha and the final version, the difference is only that the map became 3D and the shadows became worse.
