So you have your Doom 95 CD-Rom and or ISO or heck even Master of Orion 2 or maybe some other game you liked playing from back in the days.
Now you install your beloved game only to get a DPLAY.dll error saying...
* "Dplay.dll Not Found"
* "This application failed to start because dplay.dll was not found. Re-installing the application may fix this problem."
* "Cannot find [PATH]\\dplay.dll"
* "The file dplay.dll is missing."
* "Cannot start [APPLICATION]. A required component is missing: dplay.dll. Please install [APPLICATION] again."
Well I figured I could down load it and got on google and came across this

Well I tried this and it failed only to find dpx.dll wich i copied and renamed dplay.dll only to fail some more. I pondered a bit and realized it's 64 bit so wow (Windows on Windows) might have something to do with it and to look into System instead. Just as I was about to go looking into System I saw SysWOW64 BINGO!!! I thought to my self. Sure enough there is was dplayx.dll so I made copy and renamed it dplay.dll. Now doom 95 was running great till i got garbled colors. I played with in the Resolution setting tab and found out leaving windowed mode checked runs it full screen but, in normal colors!
EDIT: It doesn't seem to matter if it is set to full or windowed. it seems to reset it's self ever time you run it. Apparently the funny colors go away after the first run.
So go to..
C:\\Windows\\SysWOW64
Find dplayx.dll copy it and rename it to dplay.dll and you should have some older games working now. Hopefully this is old news to most, if not I hope I helped some one.

FYI when you run doom it will re size windows like steam or your icons if you have a crap ton.
