ScarAngel版本是StulleMule作者Stulle的一个MOD作品，基于Xtreme MOD修改。无论是CPU占用还是一些独特功能上来说，表现都相当地不俗。而这个Mephisto版本却是基于ScarAngel最新的2.5版本而来的。

Hi, this is the new official branch of the ScarAngel mod. I decided to make this a branch for the changes I had to do in order to get slotfocus are serious and very hard to make optionally. It will probably never get any further unique features but I still have some things about the Upload in my mind that might find their way into the mod at some point.

eMule v0.48a Mephisto v1.1: - 28.12.2007
based on eMule 0.48a ScarAngel 2.5 compiled with vs2003 SP1
Added: Transfer Multiple Chunks [Stulle]
Added: Adjust maximum upload time (1h-4h; default = 2h) [Stulle]
Added: Upload Tweak settings (be very careful! see documentation!) [Stulle]
Added: Veto new slot if one trickle is present [Stulle]
Added: Add new Slot if new slot is reacting too slow [Stulle]
Changed: Limitation kicks in when 1:2.9 reached instead of 1:3 [Stulle]
+ it worked but it was rather rough...
Changed: Allow PBF for Non-SUI only if state is NotAvailable [Stulle]
Changed: Accept new clients every 5 seconds instead of 10 [Stulle]
Changed: Accept new client when closing client uploads more than 1 KByte/s [Stulle]
Changed: Move PBF client down when he finished a chunk [Stulle]
Changed: Include Full/Trickle handling in slot opening process [Stulle]
+ does not effect bandwith spreading but represents it
Changed: Change between Full and Trickle only after a configured time [Stulle]
Changed: Move finishing clients down in upload [Stulle]
Changed: Calculation for the maximum to give [Stulle]
Fixed: New slot if no trickle (set wrong variable) [Stulle]

Transfer Multiple Chunks:
+ Mode 1: Do not transfer multiple Chunks (like disable the old function)
+ Mode 2: Xtreme Full Chunk (the old version of full chunk transfer)
+ Mode 3: Finish X chunks: Helps the other clients to finish x chunks (max X*PARTSIZE)
+ min 3 MB; max 9.28MB*x
+ Mode 4: Upload X Chunks: Transfers X*PARTSZIZE at the max
