Same here with the batt.dll you can test the 16-bit error by running cmd, and then type command in the opened DOS box. the problems only occur when using a "pre-patched" CD. Patching the files, replacing them in the original i386 dir and burn a cd. A post-patch (running it after installation) with either the UAE 1.2 or the "normal" 3.1 does not have these problems. (will double check this) The battery problem is only reproducable when doing an install on my laptop (it only seems to occur on laptops) the 16-bit problem is reproducable in a VM. (sorry for reopening, I posted, and then realized it was about the 1.1 version instead of the 1.2 , if you want we can make this a new thread)
