I'm trying to write a MAME guide and one of the topic is "rebuilding for an older set".
When I have converted my chd-file to V5 -> is there a way to convert it back to V4? Or must I convert it for example with two steps ? Like extracting it with chmdan V5 and creating a new chd file with chman.exe V4 again ...
Maybe someone can lead me into the right direction ;-)
