Just a short update here from my side. Today, I released version 14 of Ghosts, which reverts back to Frotz as an interpreter. So this should be resolved. I also edited the .BAT files and resaved them using CodePage 437. I am not 100% sure if that solves the issue with the .BAT file you had but I hope so. I am actually not sure what else I could do here since essentially, a .BAT file is just a text file and it just looks right. The encoding might have been it though (escape sequences and line breaks etc. might affect DOS being not able to read it properly).
