One of my favorite games of The Era, Captain Comic II, didn't want to run properly on Aemula Oldies after using Menneisyys winimage header. It runs fine with OS/X DOSBox, but would always generate 'packed file corrupt' messages. I tried copying a LOADFIX.COM binary to the image, but that would hang on execution. Rather than finding FILES or BUFFERS settings in config.sys or other DOS memory shuffling tricks, I found these utilities to uncompress the .EXE file: ftp://ftp.sac.sk/sac/pack/lzexe091.zip which gets around the ancient bug in the MS-DOS linker that caused this problem. The resulting .EXE is, of course, larger so it might affect other games that are on the 1.44MB image limit; however, for my purposes it worked great. Tip #2: There's no need to swap back to DOS when re-inserting the non-standard WinImage header. After stripping the first 512 bytes off with 'dd' you can use 'cat idosboot.dump stripped.ima > myGame.im1' to prepend the modified header. Cat works at the byte level, so it's cool.
