[Hi Briyeo! My best to the lad.]
I applied the Eye Patch to stock 1.5 and it worked, first time, but when I rebooted and tried again I had no eyes whatsoever, above *or* belowdeck.
Reading through the thread, however, I think the problem may be that I did not delete the original MARINE.DAT file but instead simply renamed it to originalMARINE.DAT and left it in the directory. I'll try re-renaming it to MARINE.THAT and see if that fixes the problem.
