Since the last post, support has been added for more or less all the iff chunks in the game (with an exception for the BHAV and OBJD chunks).
I’ve added an analyzing feature to Iffinator, to aid me in rapidly supporting new chunks. The only major thing that is currently missing is decompression of SPR# sprites, which I’m currently working on. I’ll also eventually get back to 3D rendering, but mustering the motivation to do so is difficult. I really wish I had someone more experienced to help me with that. So if you’re reading this and you have experience with 3D rendering in C# and/or the XNA API, please do not hesitate to contact me!
As far as parsing SimAntics, I’ve implemented support for Sleep and Idle commands. More will be implemented over time, but progression will most likely speed up as more of the gameplay is implemented in the client.
