I love the GS a CPI OS.
I have made some minor tweeks to mine for it to fit my needs.
Unfortunatly, everytime I update the launcher, most of my personnal settings go away.
Exemple for MAME games, I changed action.config to launch FBA instead of MAME2003.
When I did the last launcher update, the action.config file was replaced by the original one.
Same for launcher menu as I changes the order of categories and moved some icones to subfolders.
It is not a big deal to do it again but it would be great not to do it every time.
