Can some of the vehicles still work because I want to transfer the Enviro 200 from experimental to standard if it is possible
They should work if you compile from the sources using the Standard version of makeobj.
Thanks for helping, but I know it may be a stupid question but why does Makeobj come with a black box and disappear in like 2 seconds
Makeobj is a console application. That means that you need to run it from the command line and pass command line parameters to it to tell it what to do. There should be some general documentation for makeobj somewhere on the forum.
