I d/l and installed ePSXe 1.6.0 and a cumulative plugin pack suitable for several different emulators. The config wizard wasn't working saying that it wnaspi32.dll couldn't be found. The program, sat for a minute, then an error saying outofsync.bmp followed by a bunch of symbols appeared. Then the cdrom driver selection screen appeared. I went through a couple different aspi drivers to no avail. Whenever I would try to load a cdrom, the program shutdown. So I found the wnaspi.dll and put into the ePSXe folder, but it still doesn't work. Any suggestions?

You need aspi drivers. They should be included with epsxe. There's I think an aspi sub-folder where you can install it.

Use IOCTL options with P.E.Op.S CDR and you don't need an ASPI layer at all with Win2k/XP.
