Here's a quick WAD that replaces the sound effects with those of the PlayStation version. Some sound effects were being cut off too soon due to the sound ending immediately after the thing making it disappears. I included a DEHACKED lump that adds the final sprite of the multiplayer item respawn fog (IFOGE0) that has been made completely invisible at the end of some explosion animations so the sound effects can play to completion. Also included is the kickass brutal variety of the PSX Arch-Vile sound effects made by @Dexiaz   All sound effects are in the Doom sound format. Again a huge thanks to Dexiaz for the terrifying Arch-Vile sound effects!     PSXFXDEH.zip
