I'm very sorry for posting in such an old thread but i really wanted to thank you,kentucky777 for the files you posted above.I downloaded them and put them in the bin folder of MGS2 and guess what? IT'S WORKING!!! 10 years ago i bought this game but i never managed to run it in any of my old computers,even with all the help from the net,always that black screen error.After all those years,i can finally play the game in all its glory! Dsound files fixed that for me,confirmed MGS2 running on Windows 10 Pro 64bit,Compatibility mode set to Windows XP SP2 and running as administrator.Thank you once again,kentucky777!
