Manhunt 2 Debug Menu & Modding Help

Hello everyone, I’ll cut to the chase:

I recently installed Manhunt 2 a little while ago and have enjoyed multiple playthroughs and seek to enhance it with modding. Most mods are really simple, but I have tried installing Ermaccer’s debug menu and have faced some trouble. When I download the ASI loader, there are no matching dlls to replace with d3d9. The only available dlls are d3dx9_35 and d3dx9x_35, and replacing either of them with the asi loader causes the game to fail to start. This is the first game I have been manually modding and I am very new to modding, so I understand this may be a stupid thing to ask help for. Does anyone know how to resolve this issue?
