Neuer created topic a years ago on polish board “replay converting” ( ). Thanks for sharing your program! On polish forum I discussed about hash calculation, I could manipulate headers values, but I didn’t know, how are generate floors etc. If you are familiar with graphics programming, you can easily turn this replay_checker to a replay_player, or even write an Icy Tower like game, which is capable of saving compatible replays 🙂 The replay file format, the hash calculation method, and the Icy Tower physics (in fact it’s whole engine) – these are available to look at from inside.

So, what’s so special about it? It’s completely open source! This small console program does the following: loads a replay, checks it for validity (including the hash), and then silently plays the replay to verify it’s validity, just like the official itr checker. Also, the official forum is not as active as it was before. v1.4 mostly ruined the game – it became more static and ugly (no eye candy, images look stretched), harold’s got large ears and is not as cool as before, the game’s got lots of options, which makes it more complicated. Also, IMO, Icy Tower is history in general (at least the desktop game, can’t tell anything about mobile/facebook as I don’t really know what these are). Back then, v1.3.1 was the latest version of Icy Tower, and I’m sure that if I’d release it then, johanp would hate me as heck (remember how he reacted on Icy Tower Replay Editor?).

The stuff I’m going to release here is something I’ve worked on a year ago.
