A multi-version ROBLOX client launcher built to allow the user to run LAN and Internet servers. · By Bitl Development Studio
I'm just wondering. Is it still possible to fix 2012 2013 or 2014? Probably not, sadly. Although I wish they could work again.
Yes, they are fixable, but getting them patched is another story.
I don't know how, there's no tutorial to begin with.
"S" you mean 2013s as in 2013 simulation?
it is possible though bitl has no plans to add them and as far as i know there are currently no extensions that add/support these clients
eczed's modpack added these
