I use this build because it doesn't include all the home console stuff etc. As for me it's about having the space on my hard drive but I can see why people want the console stuff. There is not many builds out there just for arcade only but there could be some kind of hide all console stuff so that people like me just have the arcade only stuff showing & not having to download all the other stuff too, but thinking of it when using clrmamepro there must be a tab for it to just include either arcade or console or you would still have it showing missing roms for either arcade or console.
IMHO Please keep this build Arcade only or make 2 builds to keep everyone happy.
