which version should I use for proffesional speedrun category? Plus I've seen how to hack terribly fast wifi, but unfortunately I can't pick up how it is done, if I could also get this explanation please. Thank you
You can hack WPA2 by first writing the crack command, but with an added 0 at the end after the channel. The game will tell you, that it's impossible, but keep doing this with as many networks as you want to be hacked. After that exit wpa2 and go over to wep, where you can cycle back up to the commands you've written earlier and directly crack them without an error message.
As for the versions it's probably one where you can do the door glitches, which could save a few seconds, but given that the Top3 all ran down the hallway normally, you should be able to be competitive with pretty much any version, as long as you're lucky enough with the best red spot.
and one more question... sometimes I get this glitch with the backspace where you redirect the key to another page using the backspace key so sometimes it bugs me and it doesn't work... is there any way to fix it mid run?
Not too sure about the backspace thing but that could be the alt tab bug, where you can't copy paste text and press backspace after you alt tab outside of the game. When that happens click anywhere inside the ingame browser and press the alt key a few times and that should fix it.
