Wow that's a great response, and great theory, but how do you know it's true? I mean it makes great sense that they re-used the scripting while recreating the engine/"player" from scratch, but how did you know this? I'm just curious, I'm not questioning it however, since scripting should hold the test of time while an engine sounds like a nightmare to patch-up.
I've read/watched the behind the scenes stuff, but they just raise more questions than what they answer. What I'm trying to figure out is, was the remaster actually recompiled using the original source code, or was it just a reverse engineered or add-on (similar to how ResidualVM was able to make improvements without having the source code)?
