Doesn't matter which sections were altered, the resulting binaries are, in my opinion, inferior. RomSplit got updated, and it seems the 2nd release exec for A1200 needs 152 bytes more in the ROM; IMHO a strange effect if only two strings were changed to be few bytes longer (or maybe AmigaOS require data/code sections to be aligned somehow? I must admit, I have no idea), and definitely not a nice one.
What's even more perplexing, exec from all the Modules ADF disks I got still contain old copyright strings - if these ones are OK, than why the hell the ROM image was changed??? Amiga ecosystem has several pieces of software depending on exact ROM locations (RomSplit, various softkickers, WHDLoad, and who knows what else) - why to do such change, which can only bring trouble?
