Saveload is an interesting issue! It compares to alovolt, train levels and FPS limiter. Founder can keep although fair game is better for everybody. Since when Zweq has used it? Did DarMoeD spread it or mila programmed a new one? I have darmoed_Elma.zip from 2004-10-21 (haven't been in this deep directories for ages) but that's not the source I'm pretty sure.
Smibu published one in 2011-06-17 in Mopolauta but looks like the patch was used in style finding way before. The milatools.zip was used at least before 2011-04-01 and most likely several months before because driving those 32 tt times takes some time. FPS limiter was added to Belma in 2009-10-05 by Smibu but looks like Zweq have also had access to it before that (

So it looks like we a had a programmer-player superteam working together and referee Smibu trying to keep it fair. Apparently Russians had own team as well. Rules were not broken so it's ok. FM also had the secret foot pedal for alovolt in 2001
But since when? 2004? If I was asked to guess, I wouldn't be surprised if coding SL before EOL (2006) was more interesting

. The theoretical limit is the ultimate goal after all. At least the insane style finding spree since #255 (2007-01-06) would be better explained.
This piece of history is interesting because of the comparison to alovolt and train levels. Back then the community was much more viral and the unfair situations resolved faster than with SL (2002-2004, 2004-2011).
Did John use it?
