Ha, that's an error report I know. I got it when I installed JSGME incorrectly in a subfolder (its own folder) rather than directly in the SH4 folder.
As far as mods are concerned, I am pretty much a noob (1/2 playing maybe?) and I enjoy the mods in my signature. For some reason installing the ship physics and optical corrections didn't work for me, but TMO and RSRDC are definitely a good combo.
Good hunting
