I want 1 map file for the Sega Naomi emulation. There are 4 files for the Sega Naomi on the site. But you can choose 1 map file. So that's why I want to merge the files. When I put the lines together, the file wouldn't load in gameex. But I worked now. With Wordpad it doesn't work. With Notepad it works.
Thanks for the hint.
