Method #1:
The first and easiest method is to use the blacknull parameter, to do this find Eudemon's shortcut on the desktop or the start menu programs and rightclick it>properties:
now add the word "blacknull" (not quotes) at the end of the path under "Target":
now all you have to do is click on the shortcut normally and the game will open right away.
Method #2:
If for whatever reason the first method does not work (using a cam that doesnt allow you to specify parameters) , you could use this method to bypass the play.exe
First you need ollydbg:

look to the left menu and download it from the link
after you extracted ollydbg, open it (OLLYDBG.EXE) and go to file>open then select soul.exe from your eduemons' directory and click "open":
now wait for the application to load unless it says "paused" at the buttom right and then rightclick in the middle of the program and choose "Search for">"All referenced text strings":
a new window will popup when search is completed, now rightclick in the middle and select "Search for text":
now type in "blacknull" (no qoutes), uncheck "Case sensitive" and check "Entire Scope" and click "OK". You will find one word that matches in all References, rightclick it and select "Follow in Disassembler":
now look down from "blacknull" in the new window and look for the value:
JNZ SHORT 00587392, thats the 2nd JNZ value from "blacknull". Now rightclick this value and select "Assemble":
change "JNZ" to "JE" (notice the space after JNZ or JE keep it!). Thus we have changed Jump if not equal to Jump if equal which is the opposite of what was originally (ie if u add blacknull at the end or try to open it with play.exe its gonna give you the message "please run Play.exe"!)
now close the assembling window by clicking "X" or "Cancel" then rightclick on the middle of the program and go to "Copy to Executable">"All Modifications" and select "Copy All" in the small window that appears:
a new window will appear with your modifications, now rightclick on the new window and select "Save to file":
now save the modified executable to eudemons' directory, usually as soul2.exe (do not overwrite the original!):
close ollydbg
now whenever you want to open eudemons quickly, without autopatch or you want to use a program that doesn't allow you to specify parameters for soul.exe, just open soul2.exe and it should open right way..
