Simple actually.
1) Download my .rar. Feel free to check the VirusTotal's, the few detects are from the packer I used, I assure you all the files are clean.
2) Extract /all/ the files to the S4League folder located at C:\AeriaGames\S4League.
3) Run the program "Alu's Inject.exe" (I created three different injectors, depending on the speed of your PC. I suggest starting with the normal one, and then if you crash or something, trying the other two to see what's up.)
3.5) Upon hitting server select calmly press the F9 key. Take a second or two to admire S4's wonderful UI, then again, calmly, press the F10 key. The F9 key loads effects, the F10 key loads Items.
4)Once you're in S4, it's quite simple. Equip all the items you want to use, press the "F12" key to save the ID's.
5) Unequip all the items you have equipped.
6) Press the "F11" key to restore the items. (To check, you can go to inventory then shop to make sure your items are back on.)
7) Enter any room. (Obviously, how else would you play?)
8) Press the "DELETE" to set your items to Zero. You can check by going in your inventory, all your items should be gone from your character.
9) Go in-game, and have fun.
