I am playing this with Unseen Evil and I noticed something odd: if I load Unseen Evil first and your mod second, then the Spectre's EX sprite will be used as default even if set to 'Off' - which looks rather silly since it is much smaller than the Doom 64 Demon. However, if I load your mod first and Unseen Evil second, then I get the default Doom 64 Spectre. However, if I do the latter, your custom sound sets are replaced by Unseen Evil's Doom 64 ones.
