Flymode was disabled because all the r16xx+ versions of ascent and newer versions of mangos detected and DC the user. Deva is currently working on a new way of doing flymode but at this time it was considered best to just disable it then get a resulting xx # of posts in the thread about it DCing you.
no Fall damage was re done to bypass the some simple checks that were seen in a lot of the current emu versions, so it should work fine.
If you are concerned about a keylogger etc then either download it from the
official source deathsoft.com or don't use it.
Also this thread should be moved to the Emu section. This hack was never made with any stealth code to hide its self from warden and therefore you risk instant ban using it on any official servers.
