You could also look into forums or online communities dedicated to retro gaming, where enthusiasts often share tools and advice for working with old game files. If you're comfortable with some programming, there might be scripts available that others have created to do exactly this. Additionally, some retro game enthusiast sites may have already converted the maps and made them available for download, so a quick search could yield valuable results.
