Thanks to everyone who has posted here over the years! You can’t imagine how much you’ve helped.
I’ve owned my #LOTR since 2004 and occasionally take a break from playing it. Like a GENIUS, I left the batteries in and of course, corroded the U212 RAM below it. Had the infamous open-the-door then, constant reboot errors when I decided to play it again.
After reading all 7700+ comments on this forum and following the terryb Guide to Repairing Alkaline Battery Damage step-by-step, I was able to get it working again. I immediately installed a NVRAM!
