Thanks! :-) Glad to be here. It seems like a great community. I actually did try running the SCSI drive on it's own a few times and still couldn't get it to work. I didn't restart the machine after removing the DT drive, but there was no trace of it in Daemon Tools or Device Manager. I ended up using Launch Before/After and actually prefer the increased control. It seems a bit quirky, however. If i use the 'start' command to launch my BAT file, which also uses 'start' to mount the image, it works as expected but leaves 2 command prompt windows open (mount/unmount.) If I add 'Exit' to the BATs, GameEx fails to launch the emulator (screen fades to black, image gets mounted, GameEx GUI becomes active again, emulator process isn't runnng.) I'm struggling to determine why. Other than that, it works quite well! I'm actually using GameEx in place of HyperSpin even after donating $45 to them. (No disrespect to HyperSpin - It's cool software, but GameEx is where it's at!)
