I switched computers from a slow computer (400mHz) to a fast one (2.0 gHz). I have Windows XP with the Service Pack 2. I could not play my favorite game "Resident Evil 2 Platinum Edition" on it because the gameplay was slow. I found this site by Googling "Resident Evil 2 won't play on XP".
I saw the post about running Windows Media Player while running the game, I tried that and the game ran smoothly! So before you start the game, open WMP first. Now, about the Loading the saved Game:
I tried the compatibility issue by switching it to '95. It worked but the screen was too small, so I hit F8 and changed the Screen Resolution and the saved game loads without a hitch!
All of this with Service Pack 2 installed! So now I can play the game at Normal speed, 640x480 screen resolution and load saved games without a problem!
I gave up playing my favorite game on my PC until I found NT Compatible! Thanks guys for all of your input!
