never ending replay?

[sucre]

Hi guys!

I downloaded a few months ago some replay (don't remember address this site, sorry), which "never ended". This is link for this replay. How is it possible? Is it a bug? Are you know another interesting replays like this?

don't remember address this site, sorry

Icy.pl?

Not a bug, but rather a result of the modification of the replay.

_{I remember Jacob talking about this replay, but I cannot find the exact post.}

Welcome to the forum.

PS. Are you Polish?

[sucre]

no, it wasn't Icy.pl. This was some english site.

if is not a bug, so why this replay never end? can you explain me?

Icy Tower replays work on a principle of "playing the game again". There is information about the floors you have played on and the keys you have pressed saved in the replay.
The game starts the game on the same floors and moves the character by pressing exactly the same keys that are saved in the replay.

The author of this replay modified the keypresses in such manner that the character doesn't die when all the keypresses are replayed. Because the game has no more instructions, it doesn't move the character anymore.

Of course, you wouldn't be able to save such replay in natural way because the saving routine is only initiated after you die.

Thanks for all information! Last (i hope) question: how can i modify the keypresses like in this replay? hexditor or something else?

Hmm.

(i hope)

So, whether you'll ask more questions or not will depend on whether we'll manage to teach you to edit replays in our first reply, won't it?

Technically, a hex editor could work, but the replay would become invalid. The only reason why there's a valid replay that was edited is that the author also overcame the security measures. But we don't want to do that, because if somebody made a replay editor, it would ruin the game for everybody who played fair without cheats.

Ok, thanks guys for replies (especially John Beak). i opened some replays in hexeditor, but there are so many numbers, i don't know, what they mean. i thought, that replay editing is easy, but i was wrong

if somebody made a replay editor

Didn't Rammichael make a replay editor also?

That was for 1.3
We're talking about 1.4 here.

It feels nostalgic to remember how I played around with a hex editor until I decoded the replay format with just my own head. I could write replays almost from scratch back then. Johan added some security tricks as of 1.3 and it is (near) impossible to break those without reverse engineering.
