AMD CPU Support / SSE 4.1 pre-requisite removal patch
	for Earth Defense Force 4.1, release date version
	by Natrox (find me on Facepunch for questions)

===========================================================================
To check if you are applying the patch to the correct game version, check if at least the size of 'umbra_sandlot.dll' matches:
	umbra_sandlot.dll : 548,864 bytes
	EDF41.exe         : 13,893,120 bytes
I cannot guarantee that this patch works on any game version past the release version (July 19th, 2016).

~ The works ~

Hello,

This modified DLL allows the game to run on pre-Nov2011 AMD CPUs and other CPUs that lack the SSE4.1 instruction set. Note that your CPU will still require SSE2 and SSE3, so really old CPUs will still choke on this.

Essentially what this patch does is that it replaces the SSE 4.1 'DPPS' instructions with a equivalent larger set of instructions that work on older processors. 


~ Installation ~
Overwrite the DLL in your game directory. For most users, this should be something like:
C:\SteamLibrary\steamapps\common\Earth Defense Force 4.1


~ Is this a virus? ~
No, I wouldn't do that. If you're worried - do a binary diff and check the dissassembly, or let someone else do it for you. Other than that, I'd like to let you know that 'Craptasket' (Facepunch mod) vouches for my stuff being safe to use. But read onwards;


~ Warranties ~
I provide no warranties on this patch. I don't think this game has any anti-cheat, and I don't think the game would ban you for using this DLL - but if it does, don't blame me. If you have any questions however (technical or 'help there is a new version and the devs haven't fixed this themselves!'), feel free to contact me on Facepunch.
